How Do DERs Provide Backup Power?

Rooftop solar. Backup batteries. Smart EV chargers. Distributed energy resources (DERs) are changing the way electricity is generated, managed, and used in Ontario. In this thinkenergy short, Trevor Freeman breaks down how DERs can reduce your carbon footprint, provide backup power during outages, and help you manage your energy costs. Listen in for how net metering, load displacement, and evolving tech partnerships are reshaping the future of the grid and giving you more control over your energy.

Transcript:

Welcome to a think energy short hosted by me, Trevor Freeman. This is a bite sized episode designed to be a quick summary of a specific topic or idea related to the world of energy. This is meant to round out our collective understanding of the energy sector, and will complement our normal guest interview episodes. Thanks for joining and happy listening. Hi everyone, and welcome back. Today on think energy, I'm going to talk about distributed energy resources, or DERs. Now, if you've been listening to the show for a long time or even a short time, you will have heard us talk about DERs many times before, and for good reason. DERs are an important and growing part of our energy lives. About a year ago, I did an episode diving into what DERs are, and I encourage you to go back and listen to that one. But today I thought I do a quick refresh and talk about some of the most common ways that DERs are used. So, let's dive right in. First the refresh. DERs or distributed energy resources, are simply pieces of equipment that can generate or store power, generally on the smaller scale size of things, and spread throughout the grid. So, we're not talking about large scale, centralized generation plants here, but that small to medium scale, kind of think rooftop solar or batteries that are sized for home or facility use. And generally, when we're talking about DERs, we're focused on renewable technology like solar panels or batteries, and in some cases, you know, smaller wind turbines. For the most part on this show, that's what we're focused on. However, there are sort of non-renewable DERs as well, and we'll actually touch on that a little bit later. So, let's dive into what some of the reasons are why someone would want a der there's a couple of different reasons. The first is for backup during an outage. So, using solar panels, especially if paired with a battery, can give you some backup if there's an outage from the grid, whether that's a storm or an accident or something like that, that backup power can be focused on your key devices or systems or appliances, or if your storage is big enough, or your system is big enough, it may be used to power your whole home for a period of Time. Of course, if you're using one of those nonrenewable sources that I mentioned, like a fossil fuel power generator, for example, then your backup supply can last longer, really, as long as you've got fuel, but it's not clean, so you will be producing carbon emissions. One emerging technology that we'll likely see more of in the future is using an electric vehicle for this purpose. So, while there's only a few different models that allow this right now, the Ford f1 50 is one of them, and there are some safety and regulatory considerations before you go ahead and do this, we can expect to see more of this in the future as the technology advances and it becomes a bit more widespread. Another reason for DERs is financial. Installing a der can actually help you save money every month, whether that's just by reducing what you consume from the grid or by pushing back unused generation to the grid for credits. And I'll touch on this a little bit more shortly. Finally, if we're talking about those renewable DERs, they produce clean energy. So that's carbon, free emissions, free energy. And if you are concerned about your carbon footprint, you're trying to decarbonize and reduce the amount of emissions that you cause. DERs, renewable DERs are a great way to do that. You can lower your carbon footprint by reducing how much you draw from the electricity grid and any carbon emissions that are associated with that. Okay, so let's go back to the financial use case for a minute and talk about the different ways that that's possible. I'll be speaking about the Ontario context here. So, if you're listening from outside of Ontario, you'll have to do a little bit of your own research to figure out what options exist where you live. One option to set up your der for financial reasons is net metering, which I kind of alluded to earlier. Net metering is a setup for renewable generation sources only that allows you to use as much of your generation as you can to power your home when you're using it, and then push back whatever you don't use to the grid. Whatever you push back to the grid, will give you a credit on your bill that you can use to offset the electricity charge portion of your bill. Another option would be load displacement. With this arrangement, you can generate electricity exclusively for your own use, so you will reduce the amount that you pull from the grid, and that will save you money, but you don't push anything back to the grid, and therefore you don't earn any credits. And finally, there are standalone generation setups. This arrangement involves pushing all of your generation back to the grid for some agreed upon compensation. While there used to be programs for small scale standalone generation so you might be familiar and on. Ontario with the fit or the MicroFit programs that existed about 10 years ago. These programs are closed today, and generally only large generators have a standalone arrangement. Now, like any technology, DERs are not free to install. In fact, they can be quite pricey in some cases, but because they provide benefit to the grid. There are incentive programs out there to help reduce the upfront costs. Here in Ontario, the ISOs save on energy programs provide an incentive to any customer type, from residential all the way up to large commercial to install rooftop solar, and homeowners can access additional funding to install the battery along with their solar. If you're interested in doing this, or you want to learn a little bit more, you can reach out to your LDC, visit our website. If you're in hydro Ottawa's territory, or visit save on energy.ca. In the near future, you will also likely see more utilities wanting to partner with der owners. I talked about this a little bit in my last episode with Andrea Nusser About grid modernization here at hydro Ottawa, we are working on a technology project that will be launched next year that will enable der owners to leverage their devices for an incentive to help manage the grid in targeted areas. It's pretty exciting stuff, and it's really the next wave of distributed energy resources on our grid and how we're going to interact with them. It's pretty exciting. So, there you have it. That's a quick summary of the different ways that DERs are used. If you're looking at installing a der in your home, whether that's solar or battery or anything else, or for your business for that matter, have a look at our website. Make sure you fill out the application forms and reach out to us so that we can help get you set up and get you using your der thanks for tuning in to another think energy short and look forward to chatting with you next time.
