Yes. Nick, it's Kevin. There's a couple of things in that -- in your question. Let me first start with, as you heard in my opening comments there, our team has and continues to stay very attuned to and keep affordability at the top of the mind and focused on how we can help. You heard the things that our customer service organization, our customer advocacy team are doing with outreach to energy assistance organizations, trying to find funds, get customers connected to that, find ways we can communicate proactively with customers. For example, during the last winter period, we sent out, think about 1.5 million notices, whether those were phone calls, where those were text, whether those were e-mails, those sort of things, trying to alert customers to pending colder than normal situations moving into the area.
We're also sending them through those various channels, including social media as well, information on weather tips, energy efficiency, conservation, gas cost pricing, all those sort of things. So we're trying to stay very active with our customers, very up-to-date with our customers on the cost, but also find ways where we can help through our energy assistance LIHEAP programs, point them to the locations where they can receive assistance. But also, as you know, we're a very efficient operator. We work very hard at that.
You've seen the things we've done over the last couple of years through Uri. Those sort of things will continue those efforts as we monitor the gas price over the next few months, and we'll continue to communicate with our customers where we can.
And to the second part of your question there, I think where you were heading regarding our capital investment program over the 5-year horizon, I think as you can see in our slide deck right now, we run somewhere between 85% to 90% of our capital investments focused on safety and reliability. That needs to continue and will continue as we continue our strategy to modernize our system for safe delivery of natural gas as well as, as you just heard me mention that growth out there to support that high growth rate, particularly when we're adding 12 months ending March, 57,000 new customers out there and 15 new industrials.
So we've got to continue to meet that growing positive and strong demand for natural gas across our service territory that we anticipate will continue going forward, as we talk to builders and developers out there. Even with interest rates at 5% right now, they're continuing to see strong demand as well. So that's what we're going to focus on, how we help the customer, how we can connect the customer to the right assistance organization, maintain our focus on O&M where we can and then continue to invest in our system.
