Good morning. My name is Sylvie and I will be your conference operator today. At this time, I would like to welcome everyone to TransAlta Corporation’s Second Quarter 2021 Results Conference Call. [Operator Instructions] Thank you. I now would like to turn the conference over to Chiara Valentini, Managing Director of Strategic Finance and Investor Relations. Please go ahead.

Great, thank you Sylvie. Good morning everyone and welcome to TransAlta’s second quarter conference call. With me today are John Kousinioris, President and Chief Executive Officer; Todd Stack, EVP Finance and Chief Financial Officer; and Kerry OReilly Wilks, EVP, Legal, Commercial and External Affairs. Today’s call is being webcast and I invite those listening on the phone lines to view the supporting slides that are posted on our website. A replay of the call will be available later today and the transcript will be posted to our website shortly thereafter. All the information provided during this conference call is subject to the forward-looking statement qualification set out here on Slide 2, detailed further in our MD&A and incorporated for the purposes of today's call. All amounts referenced during the call are in Canadian currency unless otherwise stated. The non-IFRS terminology used, including comparable EBITDA, funds from operations and free cash flow are also reconciled in the MD&A for your reference. On today's call, John and Todd will provide an overview of the quarter's results, along with our expectations for balance of the year. After these remarks, we will open the call for questions. With that, let me turn the call over to John.

Thank you, Chiara. Good morning, everyone. And thank you for joining our second quarter call. As part of our commitment towards reconciliation I want to begin by acknowledging the TransAlta’s head office where I am today is located in the traditional territories of the Niitsitapi the people of the Treaty 7 region in Southern Alberta, which includes the Siksika, the Piikani, the Kainai, the Tsuut’ina and the Stoney Nakoda First Nations as well as the home of Metis Nation, Region 3. We've had another outstanding quarter. I'm extremely pleased with the performance of our company and the progress that we've made in advancing our priorities. In Q2, we delivered a 39% increase in comparable EBITDA, which has resulted in a 55% increase in free cash flow per share quarter-over-quarter. And year-to-date, we have generated a 40% increase in comparable EBITDA, which has resulted in a 38% increase in free cash flow per share year-over-year. Based on our strong year-to-date performance, along with our expectations for the balance of the year, we're pleased to increase our EBITDA and free cash flow guidance for 2021 by 13% and 22% respectively, at the midpoints compared to the original guidance we provided for 2021. Todd will provide more details on our revised guidance later in the call. Our access to liquidity remains strong, and we're able to fully fund our remaining conversion to gas and Keephills 3 as well as our growth pipeline, and we continue to achieve improve safety performance year-over-year. Our performance this quarter was driven by operational and optimization excellence across the fleet, which enabled us to capture the higher prices experienced in Alberta. The Alberta team has developed key operating strategies that ensure our fleet has high availability during periods of increased demand, so they're able to provide reliable power…

Thanks, John. We had an outstanding quarter, and our diversified fleet continued to deliver strong results $302 million of comparable EBITDA driven by robust results in our Alberta electricity portfolio, and our energy marketing business. Strong EBITDA results are reflected in our free cash flow numbers for Q2. In the quarter, we generated $138 million or $0.51 per share a free cash flow. On a year-to-date basis, the company has generated $612 million of EBITDA and $267 million of free cash flow. We are extremely pleased with our performance so far this year. With the expiry of the PPAs, both our Alberta Hydro and Alberta Thermal segments benefited from strong pricing in the Alberta market, as well as from the great work of our asset management and optimization teams. EBITDA from our hydro fleet continued to significantly outperform this quarter, realizing an over threefold increase from $29 million in 2020 to $96 million this year. EBITDA from the Alberta Thermal segment also significantly increased year-over-year from $30 million in 2020 to $85 million this year, although I note that realized cash flow at Alberta Thermal continues to be impacted by the plan sustaining capital expenditures related to our conversions to gas. Our energy marketing team delivered another strong quarter in line with excellent results delivered in Q2 of 2020. Production from our Wind and Solar segment was lower than 2020 due to lower wind resources across all regions. This impact of lower wind resource was partially offset by the addition of the Skookumchuck facility. Results from the North American gas segment were below expectations due to unexpected outages at our Sarnia facility. The decrease in EBITDA was partially offset by the addition of the Ada facility and higher realized pricing in Alberta at the Fort Saskatchewan plant. Centralia’s EBITDA decreased…

Thanks Todd. As I review our 2021 balance of the year priorities, we continue to focus on progressing our key goals, including securing a growth project in the United States, completing the construction of Windrise, completing the Keephills 3 coal to gas conversion, completing the recontracting of our Sarnia facility, advancing our organizational health and equity diversity and inclusion initiatives and delivering 2021 EBITDA and free cash flow on the basis of our revised guidance. I'd like to close by highlighting what I think makes TransAlta a highly attractive investment and a great value opportunity. First, our cash flows are resilient and supported by a high quality and highly diversified portfolio as evidenced by our year-to-date results. Our business is driven by our contracted wind portfolio, our unique, reliable, and perpetual hydro portfolio and our efficient thermal portfolio. All of which are complemented by our world-class asset optimization and energy marketing capabilities. Second, we're a clean electricity leader with a focus on tangible greenhouse gas emission reductions. Our de-carbonization journey has resulted in greenhouse gas reductions that represent close to 8% of Canada's 2030 target. In addition, our focus on removing systemic barriers through our commitment to equity, diversity and inclusion, as well as good governance places as well ahead as a leader in ESG. Third, we have an extensive and diversified set of growth opportunities, which includes a pipeline of advanced stage projects and a talented development team focused on realizing its value. Fourth, our company has a strong financial foundation. Our balance sheet is in great shape and has ample liquidity to pursue growth. Finally, our people are our greatest asset and I want to thank all our employees and contractors for the work that they have done to deliver our results this past quarter. We're committed to a company culture where everyone belongs and can bring their best and authentic selves to deliver great results for our company. TransAlta had an exciting time in its development and we are well positioned for the future, as a leader in low cost, reliable and clean electricity generation focused on serving and meeting the needs of our customers. As I mentioned in the last quarterly update call, we will be hosting our 2021 Virtual Investor Day on September 28. At that time, we'll explore with you our strategic plans for 2022 and beyond. With that, I'll turn the call back over to Chiara.

Thank you, John. Sylvie, would you please open the call up for questions from analysts?

Certainly. [Operator Instructions] And your first question will be from Mark Jarvi at CIBC Capital Markets. Please go ahead.

Thanks everyone. Just want to go to the Sun 5 repowering – this commentary about evaluating, just wanted to see what your sort of implying there around costs when you're out there, we are looking for again – at updated bids. Are you implying that the cost can go up from the 900 to 950? And then the second part would be, if you don't like where the costs are, and questions around supply demand, like what are the options? It seems like you've retired the asset effectively, so that can – maybe employer conversions or that simply just – or nothing in terms of the repowering for Sun 5?

Good morning, Mark. Thanks for the question. So, on Sundance 5, so there is a number of questions that you had in that. In terms of what we were signaling, in terms of the increase in costs we were seeing in the unit, we continue to be broadly aligned, there. We went out and did another tender process to make sure that we were getting the best possible that cost that we could for the project. We continue to evaluate going forward. We've made no decisions on finally proceeding with the project. We're for sure looking at kind of the evolution of supply in the province over the course of the coming decade. And thinking about everything on when it would make sense to bring the unit which might be exactly as currently planned. And also continuing to assess kind of the regulatory environment in terms of the implications of the federal government's approach to carbon pricing for new combined cycle gas plants. So that's all in the mix. And that remains live in terms of the assessment that we're doing for that project. In terms of the mothball, I think it was on July 28, we made the announcement to basically end the mothball. So, the unit will not be returning on November 1. Remember it hasn't been converted to a gas unit. It would have been required to run on coal-fired generation. And as you know, we're shutting down the mine at the end of the year. So really for us this is – it's almost an administrative kind of approach where we're parking the unit at this point in time. No plans to bring it back prior to making a decision on Sundance 5 and certainly not making any decision to bring it back on coal nor having made any decision to do a coal to gas conversion there either.

But just to be clear you still could go to a Plan B and do a simple conversion like you did for the Keephills Unit and Sun 6 if you so choose?

That would be possible to do there. Yes.

And with a timeline of the first half of 2024 to stick to that target completion date if that's what you intended, when would you have to make a formal decision on Sun 5 not to go ahead?

I think just going from memory, it would be sometime later this year, Mark.

Okay. And then, can you guys provide a bit more context on the thorny issues with the steam interruption in terms of whether or not there's any costs still to bear and liquidated damages or essentially what we saw as a hit to the Q2 numbers is all gone and there's no forward impact?

Yes, Mark. I – so we had three very unusual for us very typical. I think as Todd said in his comments, we had three outages in – I think Todd it was over the course of about three weeks. It was very unusual in terms of steam interruptions there. The plant is up and running. We're not expecting any sort of significant sort of sustaining capital or other capital costs associated with the outages. The liquidated damages are effectively as shown in the financial statements, so effectively the event which was unusual is contained from our perspective and we're really proud of the way that we were able to work with our customers in Sarnia to kind of bring them through the channels that we were facing and be as responsive as we could to their needs.

Okay. That's good to hear. And last question and it is for Todd. Just in terms of the hybrid solar project in Australia, the economics that you guys have shown from the CapEx and EBITDA projections, I assume is sort of like TransAlta core. How would we adjust those numbers, I think through in terms of what that might look like at the TransAlta Renewables level in terms of either development premium or associated costs in terms of bringing that outside online? Just in terms of what that could look like on in terms of EBITDA lack of TransAlta renewals?

Yes, Mark. I would say in any development, if it is modest, those economics effectively rollup to a TransAlta Renewables.

Okay, great. Thanks. That's all I had.

Thanks.

Thank you. Next question will be from Dariusz Lozny at Bank of America. Please go ahead. Please go ahead, Dariusz.

Hi, good morning. Thanks for taking my question. Just wanted to touch on the unplanned outage and Todd, can you just speak to that in a little a little bit more detail, please. I know the queue kind of reference that there were three separate events. So just curious if you could give a little bit more clarity as far as how those went?

We had, I'm not sure that there is a lot more that I can give you Dariusz. We had sort of three technical issues which occurred, I think two of them occurred pretty, pretty proximate to each other and then we had a third one that recurred – that occurred subsequently. They weren't related events. They were very much sort of standalone events and the facility is back up and running at this point in time. Todd, over to you.

Yes. Maybe I'll start a bit more color. Steam interruptions are extremely infrequent and rare in these facilities as you know the co-gen facility especially Sarnia's designed with a lot of N minus 1 duplication reliability in order to maintain that steam supply to customers. In this particular case, the first outage occurred and while they were in the process, they did restore steam supply, but not fully restore all of the redundancies in the plant and while they were in that process another event that normally would have been covered through redundancy and unfortunately all of the redundant systems were not back up and running which triggered another outage. And so, they were just into a bit of a catch-up game of trying to get the plant fully restored to all of its N minus 1 reliability which is why a couple of these events triggered. But as John mentioned they were unrelated and it is extremely rare event and it's just unfortunate that all of the redundancies weren't actually available for the second and third events.

Okay. Thank you for that added detail. And one more just on the RNW updated guidance if I could, just you've referenced some lower-than-average wind performance for the first half of the year. Can you speak to sort of what's embedded in your expectations for the balance of the year at the wind assets and also broadly across the portfolio?

Yes. Unfortunately, in wind, you can't say that the first half was at 90% and the second half will be at 110%. So also, our balance of year forecast is based on a P50 results. So basically, an average second half wind result. Again, we did see a lot of heat in July. So, July as well was a weak wind resource. But the back half of the forecast is based on sort of average production.

Yes. I think 92% in the first half.

In the first half. Yes.

Yes. Okay, great. I'll leave it there. Thank you very much.

Thanks, Dariusz.

Thank you. Next question will be from Rob Hope at Scotiabank. Please go ahead.

Hello, everyone. I want to circle back on Sun 5 and kind of the evaluation of that project. One point of clarification, the off-take block with Shell from the Connecticut turbines. If you were not to proceed with Sun 5, could you put those over to your other portfolio?

Yes Rob, that's a great question. So, we do not view the arrangement with Shell as being contingent on any specific unit. So, our view is that we would be able to allocate them to other areas of the portfolio of generation in the province.

And then I guess just more fulsome in terms of kind of a capital allocation question. Sun 5 if it costs further increased was quite a bit of a capital spend for a good amount of merchant capacity there. When you take a look at the suite of projects that you have under the umbrella, are we increasingly seeing better opportunities on the renewable side and Sun 5 doesn't go forward, could we see increased investment in renewables, as well as a potential acceleration of the share buyback?

Yes. Rob, that's a great question. So, when we look at sort of Sun 5, and we look at sort of the development pipeline that we have. We tend to look at them kind of an equivalent level in terms of, how they compete for capital allocation in the company. So, when we look at our renewables fleet, which to your point would be more bite sized pieces more contrasted. Probably, in some respects, lower risk, it just factors into the way that we're looking at the capital allocation between the two. And in the event that we want to proceed with Sun 5, or it ends up being developed in a different kind of manner, there would potentially be more capital to accelerate kind of the renewable side of the equation. In terms of share buybacks, I mean, Todd, you can comment about that, too. But, you know, we're very much focused on doing that, when we think it makes sense to base on the trading price of the of the shares. And, you know, we've typically bought them at prices, sort of at a sub $10 level. And given where we're trading right now, the share buybacks aren't I don't want to put words into Todd's mouth kind of a priority for us.

Actually, I think that's a fair characterization that we see a lot of good opportunities to deploy capital. Certainly, our capacity to buy back shares is there to you know, support the stock and buy it back at and opportunistic prices.

Okay. And then just one follow-up question the Hedland settlement that was struck in May any updates there in terms of progress and well as potential uplift in EBITDA?

Sure, I might Rob, I might turn that over to Kerry. Hopefully you can hear her here.

Hi, Rob, nice to hear from you. We're still in the process of finalizing the settlement. And we should do so in the imminent in the coming weeks.

Thank you.

Thanks, Rob.

Thank you. Next question will be from Maurice Choy at RBC Capital Markets. Please go ahead.

Thanks very much and good morning. My first question is just also another follow-up on Sundance 5, it sounds like everything is, remains on the table, including a boiler conversion like Sun 6. But within your list of options that are in front of you, is there any contemplation to repower the project using newer and efficient technology instead of the ones, instead of turbines from Kineticor and to that end? How marketable is it to sell the Kineticor turbines that you bought back in 2019?

Yes, Maurice good morning. Thanks for that. Look, we are looking at Sundance 5, including sort of the competitiveness of the unit in light of the new bill that is being proposed to be to be added to the province over the course of the next seven or eight years or so, which is pretty significant. We're still in an evaluation phase, I wouldn't say that we've made any kind of decisions in terms of, replacing the class of turbines that we have. For example, different class of turbine or turbines that would have a dual fuel capability, for example so I don't want to speculate in terms of, where that would land. And at this point in time, wouldn't comment on not proceeding with the project and what we'd be able to recoup for the existing there.

Fair enough. And not that I want to tee up the September 20 event, but is it likely that we will hear more about that on that day in terms of decision making or is it more like end of year type of decision?

We're working hard to be able to provide more clarity, certainly by Investor Day Maurice.

Great. And just to finish off, I wanted to just come back to energy marketing. Obviously, the guidance has been improved to $170 million to $200 million. And that represents an upward trend from $120 million back in 2018, $140 million in 2019. I recognize that some of the strongest performances are more circumstantial, sometimes based on different years. But is there a sign of a more permanent change in the profitability of this segment moving forward?

I'm going to turn that over to my friend Todd, who oversees the group.

Yes, good morning I'm not sure like, certainly the floor is well positioned to take advantage of opportunities that present themselves in the market. And really the regions we're talking about here are the Western and Eastern U.S. markets as well as natural gas across North America. And really what it takes there is market opportunity. And so, volatility is one of the key things that they look for, price dislocations, and really the opportunity to source power to source energy in one jurisdiction, and move it to another and that's predominantly how the team looks to generate profits. And that's something that we've seen, whether it's from heat waves in certain areas or cold periods in other parts of – times of the year. Even quite frankly, forest fires and other disruptions of transmission and et cetera gives the team's opportunity to look for margin by moving power around and arranging transport and transmission. So, I would say volatility is what creates the opportunity. And renewables is a big part of that volatility as well. So, I would say we are seeing, structural changes that that could see an upward shift in that number.

Yes, and I just think, I think Todd with the increasing heat that we've seen over time in that part of the world, and increasing demand, the change of the generation mix, certainly volatility is increased, and the fourth thrives on that.

Yes.

Fair enough. Thank you very much.

Thank you.

Thank you. Your next question will be from John Mould at TD Securities. Please go ahead, John.

Hi, morning everybody. Maybe just to circle back to Sun 5 again, looking back at your Q1 disclosures, you had referenced issuing full notice to perceive later this year, so obviously that vein which has been pulled back a little bit, I guess, what’s changed since May in your broader outlook for the project either in the power markets, regulatory outlook be at there may be CCS requirement down the road, or build cost picture that’s just may be take a bit of step back this quarter?

John, I think it’s a great question. I think it’s a lot of things. When you look at the project, I mean, we’re very much looking at, I’ll just give you an example, carbon pricing going to $170 seeing the federal government signal that the performance standard for new gas like Sun 5 would actually decline to zero by 2030 time period in terms of just directionally where they are going and seeing that being fully exposed to the carbon price as it’s increased over the coming years, we’re very mindful of load growth in the province and looking at the increase in the amount of proposed generation, both on the gas side and on the gas side and on the renewable side and working to understand the implications of that for generation in the province as we go forward. So, it isn't any one thing, John, it's a confluence of things that, I think, we're prudently looking at in the context of making the right decision for our shareholders.

Okay, great. Thanks for that. Go ahead.

I would just add that CCS is also a pretty big uncertainty. I mean, it is expensive technology, our assessment would have the cost of CCS CCUS be at least equal to the cost of the actual repowering of the project. And it isn't necessarily the case that the technology associated with that is a fait accompli. So, I wanted to just sort of give you a bit of a complete picture.

Okay. Thanks for that. And then starting turning to Sarnia and the re-contracting outlook there, just wonder about your thoughts on how the re-contracting outlook there has been informed at all by the recent annual acquisition report that the AESPO published?

Yes, it's a great question. So, for us, there's really three elements to Sarnia and I can turn it over to Kerry to add any color if I omit anything. One is, we do have the Blue Water Energy Park there, and we're working hard to actually expand off-takers on the facility and we're having some success in doing that. Certainly, over the course of the quarter, we're expecting some of the crypto miners to be interested in that. And we're seeing some success in terms of supplementing the cash flows there. Two, as we indicated in the quarter, we are focused on re-contracting with our four major off-takers there, we have completed one, discussions are advancing well with the other three. And it's kind of good just to have one of them done and creating kind of a good template and sort of a benchmark in terms of pricing for the facility as we go forward. And we're pleased with how that has gone and is going. And then finally, it's – the ongoing discussions with the AESO, we're actually pretty optimistic, about our ability to recontract a chunk of that plant with the ISO it is located in a part of the province that we understand does have a power need, it's important in terms of backstopping the needs of industry in that particular region. And the size of the off-take that at least we understand the AESO was looking at is sufficiently large given what would be available to participate that we think it creates a good opportunity for us to be competitive in that and actually secure something that underpins the plant going forward. Kerry, I don't know if there's anything else you'd add to that.

No, I would just note that we're very pleased that they've released the guidance. We appreciate that it's still in the design phase. We're also confident given that amount of megawatts that we'll be able to be fit into the process is limited to the to providers that will be coming off contract at the same time as Sarnia. And we're working closely hand-in-hand as we always do with the Ontario government, with the goal that we provide them with the energy that they need and that we are obviously able to contract this facility to provide our shareholders with those returns as well.

Okay, great. Thanks for that. And maybe just one last one on your growth pipeline, just looking beyond the Oklahoma projects, which I understand you're advancing offtake discussions there. Where are you seeing among your mid stage pipeline, the best opportunities to secure potential offtake agreements and move those projects forward?

Yes, thank you for that. So, we think it really falls into three areas. We do think that there continue to be opportunities to grow in a similar fashion to what we've seen serving our customers in Australia and our development team there continues to work to land that. And I think that might be a little bit of gas, but also potentially additional solar that we're able to do there, and even potentially wind to be honest in Australia. In Canada, we're pretty excited about the ongoing demand from industry, institutions, commercial entities, for renewables here. We're working hard to advance our wind farms that are under development in the province here. And I'm thinking of Riplinger and Willow Creek, would be just an example of some of the wind farms there. We’re also in the early stages of developing solar in the province, both near Highvale and also in the southeastern part of the province, which we also think is something that we could bring forward. And in U.S. we continue to see a lot of opportunity in Illinois with our Prairie Violet project. And the team is doing a really good of increasing our opportunity set in PJM, where we continue to see really strong, PPA off-take demand. So, it's really John all three jurisdictions. And I'm really pleased with the fact that we now have defined and identifiable projects that we can specifically kind of feather in the medium term.

Okay, great. I'll leave it there. Thanks very much.

Thanks, John.

Thank you. Next question will be from Andrew Kuske at Credit Suisse. Please go ahead.

Thanks. Good morning. I think at the MD&A there's a comment that in Alberta, if you were fully converted in your fleet, your carbon compliance costs would be $15 million to $20 million lower. So, I guess the question is more of a broad one on how do you think about the tension in the market of lower carbon compliance costs for some like yourselves in the conversion process versus escalating carbon prices that are happening on a legislative basis? And where do you think clearing prices wind up? Is there an upward bias over time because of the carbon prices increasing, but there's also a generation mix that's changing in the province?

Yes, it's a great question Andrew. Maybe I'll try to answer it this way. So, we do think that maybe I'll try to answer it this way, so in general, from a trend perspective, the carbon intensity of the provinces has declined and I think is going to continue to decline. So, for sure, I think, over time we will continue to see that happen. The decline though is happening at a rate that is a bit lower than the carbon prices increasing. So, we do think that when you get to the sort of the mid and back half of the decade, for sure that will continue to be an increase in carbon pricing, that'll be impacted and showing itself in the price over time. And in part that's, because we're – at least our company is presently expecting to see that performance standard for new gas decline over time. So, we do see a more muted impact, I think, the near term, but over time, I think, it becomes more and more significant as you get into the certainly 2028, 2029, 2020 – 2030, and kind of the bigger numbers are there. And it kind of bites into the emissions profile from whatever natural gas generation exists at that time. I don't know if that answers your question, but…

It does. It's helpful color. And then maybe flipping to just another part of your portfolio in Alberta, what opportunities do you see for really structured power deals on a renewable basis, and being able to capture premium pricing for some 24x7 kind of green power deals. We've seen them in some other jurisdictions, very few players can offer them, does you need a portfolio of assets across the ecosystem to do it? But you seem to have all those things. So, what are you seeing on that front?

So, we actually think it's one of the biggest opportunity sets that we actually see Andrew. I'm glad you raised this. I'm not sure that our off takers at least today are quite there in demanding, that product in Alberta that might change, over time. And we're actually seeing a greater focus on that with the mining community in Western Australia, where they're very much interested in reducing their emissions, but also having an element of reliability. And I think in part that's just the remote nature of their operations. So, they are not tied into the grid. And as a result, it's more of an acute issue with them. But I do think that it will become more important over time. And I think you're right between our existing wind fleet and certainly our hydro fleet, we do have the ability to shape, and we're actually looking at some of the opportunities to add a pretty meaningful amount of storage, potentially tied to existing, renewable assets in the province. And that's not just wind, but potentially our hydro fleet that can also help some of that shaping in addition to maybe helping meet some of the ancillary services needed the province might have in the future as the renewables build out continues. So hopefully that gives you a bit of a sense.

That does, thank you very much.

Thanks, Andrew.

Thank you. Next question will be from Naji Baydoun at IA Capital Markets. Please go ahead.

Hi, good morning. I know you touched on this earlier, but I just wanted to go back to corporate partnerships. So, far this year you've got Garden Plain with Pembina Goldfields with BHP, it sounds like there's another project or more coming from the us. Do you really see corporate partnerships becoming the path forward for growing your renewable portfolio? And if so, what are some of the resources or investments seem to make today to capture those opportunities?

Yes, Naji, great question. So, when we think of our renewables’ growth and frankly, the way we're approaching growth, it is very much customer centered. So, our goal is to actually have our development team. And I think this is where we do best to actually be essentially embedded with our customers or prospective customers, helping them come up with solutions to meet their needs. So, do I expect our renewable build out to be largely contracted? I do. Do we expect to see more, partnerships along the lines of what we have seen? I think we do. And it's something that we talk about explicitly and are spending a lot of time at the company, making sure that our whole approach to dealing with customers is top of mind. It's actually a real focus internally and that's everything from the way we interact with customers to the way that we try to standardize our approaches to make it easier for our teams as we integrate our growth going forward.

Okay. That's so helpful. And maybe just another question on your development pipeline, still mostly consists of one opportunity today, but do you believe you need to maybe diversify or add to your development teams to try to get in a bit more into solar and storage? And if that's the case, how do you view solar storage in terms of risk, return, trade off versus wind?

Yes, so we do have storage in our portfolio and are actually in the process now of developing incremental storage not just in Australia with what we've just done with BHP, but frankly in Alberta. As we go forward, we think the return equation for storage is becoming better all of the time. And the work that we did with our wind charger opportunity really helped, I think, de-risk our own understanding of what we can do with storage in the province and how the economics work. So, frankly, we're pretty positive about storage, notwithstanding the fact that the cost of storage remains on the high, it's a little bit higher than we'd like to see it. But it will trend down. On solar, look, it is a highly competitive space, the returns tend to be compressed, certainly compared to the opportunities that we see from a wind perspective. We are though focused on developing our own solar and also canvassing potential acquisition opportunities. On the solar side we think it's an important technology for our company to have a skill set in and that remains our focus. It's pretty disruptive candidly in some parts of the world. And I think as we are looking at the energy transition taking place it's important that a company like ours has some silver capabilities. So, I think you'll see more of a focus than we've traditionally had on solar in our company.

Okay. That's great detail. Thank you.

Thanks, Naji.

Thank you. [Operator Instructions] The next question is from Patrick Kenny at National Bank. Please go

Thank you. Yes, good morning guys. Just a couple of follow-ups here. So back on the Alberta Hydro results and the healthy realized price achieved relative to spot. I think he touched on it, but can you just clarify how much of a factor that heat wave late in the quarter might've played into elevating the strong performance there, or did everything play out as expected and that 30% or so realized pricing premium over the fall market is what we should expect from the portfolio going forward, especially as it relates to the seasonally strong second quarter?

Yes, I would say Patrick, first of all, good morning. I would say that I'll try to answer the question maybe in reverse the kind of premium that we're talking about, realizing on the energy side to just sort of the spot price from hydro is I would say Todd broadly where we would expect our hydro to come in on the energy side. So, we would expect it to be broadly having a premium to spot in terms of kind of the prices that we saw over the quarter, for sure they were in part due to the high temperatures that we experienced. But there were issues with the inter tie, there were outages that were pretty significant, load has come back pretty dramatically, in the province. So, it was a confluence of a number of events that resulted in [indiscernible] strengthened supply and demand kind of fundamentals over the quarter. Todd, I don’t know if you want.

So, I would say nobody expected the really high temperatures that we saw in Alberta in June, it was abnormal. As far as the premiums on the hydro, it is somewhat correlated to how volatile the power prices are if typically, in shoulder months that we would see in like April, May, we would see as more softer prices…

More compression.

More compression, which doesn't give you as much opportunity to realize the peak pricing and the super peak pricing in hydro. But certainly, as John mentioned, there was outages, there were [indiscernible] outages and then driven by demand because of the heat presented all of those opportunities. But we typically do see it in the winter months where we can realize the premiums and then also in the warm summer months of July and August, for sure.

Yes.

Okay. That's helpful. Thank you. And then just back to Sun 5, so say it does not proceed. Can you maybe just help us square up your gas supply commitments on Pioneer and NGTL, I believe it's 400 plus million a day starting in 2023. Just square up that commitment with your internal gas consumption forecast under a boiler conversion only scenario across your Sundance and Keephills units. Just want to make sure that you won't be offside with your commitments if Sun 5 does stay on the shelf for a little while.

Yes, and I wouldn't say that we would be offside any of our commitments. I mean, look, Patrick, it's a great question, but I'd be speculating right now in terms of how much gas we would need depending on the decisions that we ended up making with Sundance 5, which could result in it proceeding or not proceeding or proceeding in a different way than we've currently sort of anticipated. In general, we've got more than apple sort of gas supply going forward as we begin our assessment and evaluation of the plan, we do look at the gas supply equation, and the team looks at to the extent we have excess supply, what does it mean in terms of us being able to market a remarket those commitments going forward. But hopefully that gives you a little bit of a flavor Todd, I don't know if you want to add anything.

Yes look, I think, there's work to be done. But again, like Sun 5 is part of that equation as well. But remember, I mean, we procure gas as well to make sure that we have firm supply for all of the peak days as well. So, that does mean by nature there are going to be days where you're not actually using the entire firm commitment. So, I don't see it as a big mismatch or anything at this point in time. And again, no decision has been made on Sun 5.

That’s right.

Okay. That's great. Appreciate the color guys.

Thanks a lot.
