Yes, sure. This is Brannen. I think as Wes said, and I think actually the slide -- I mean, in my view, actually lays it out well, even from a modeling standpoint, if you kind of just start with the basics for what we have today, which is 25 TBtu going into San Juan 5 and 6, and then you look at the temp power that has now really been converted to permanent power, which all in is 425 megawatts that exists today. And then if you look at the existing assets that are in Palo Seco and then you look at the opportunity, for example, in Mayagüez, and to add supplemental power depending on the month you want to pick, and depending on how you want to kind of model that in, the way I kind of think about it is you're likely to get there certainly by the end of the year.
And then on a ramp rate that starts off at 20 plus 30, so it's 50, going to 80 over the next 1.5 quarters but depending on how you want to kind of think about that. I think the drivers of timing that you -- on our side, we're obviously racing to settle quickly are a little bit of infrastructure, a little bit of logistics around asset movement and then, of course, finalizing permits and permissions that you might need to increase utilization at some of these sites. But all of these are things that are in progress. I would say they're just very ordinary course events from a development perspective. And if you look at our history in Puerto Rico, we've obviously been highly successful in getting those things done in the past.
We've never not done it. Not to say there won't be bumps in the road going in the future, but we're very confident that we'll be able to do that. And then even beyond the 80, I think as Wes indicated, I mean there's incremental opportunity that we're working on at the same time. So I don't think our view, certainly, my view is I don't view 80 as a ceiling. I view it kind of as a start and then we want to see what we can do from there. It's very clear that the mega trend there is all the oil-fired and HFO stuff is going to be retired. On the Genera platform, we're in charge of those retirements.
That's certainly driving that schedule. And so we're highly motivated to have that happen, not only because it is the right thing to do but the island desperately wants to get to a scenario where they are gas-fired plus solar and battery. But I think that's how we kind of see it towards the end of the year and certainly going into next year. But the trend is sort of, in my view, kind of up and to the right.
