SRP Solar Plans Explained: Choosing the Right Rate for Your Home in 2026

Let's talk about the plan that scares most people away: the Average Demand plan. When I first heard the term "demand charge," I thought it sounded like a penalty for being a good customer. In a way, it is! SRP looks at your highest 30-minute window of usage during the peak hours (usually 2 PM to 8 PM in the summer) and charges you a fee based on that "spike." I once had a friend who accidentally ran her dryer, her oven, and her AC at the same time on a Tuesday afternoon, and that one 30-minute window set her "demand charge" for the entire month. It’s like being graded on a whole semester based on one pop quiz you weren't ready for!

But—and this is a big but—if you are a "power ninja" and you know how to manage your spikes, this plan can actually be the cheapest option. In 2026, with smart home tech and battery storage, the Average Demand plan is where the real savings live. A battery can "shave the peak" by providing power during those 30-minute windows so SRP never sees a spike. I’ve seen homeowners drop their monthly demand charge from $60 down to $12 just by using a small battery to smooth out the bumps. It’s a bit of a triumph when you realize you’re paying the lower "off-peak" rates for almost everything because you outsmarted the demand meter.

If the idea of monitoring your microwave usage makes you want to pull your hair out, the Customer Generation plan is probably your best friend. This is the "standard" solar plan for SRP customers in 2026. It doesn't have those scary demand charges, but in exchange, the per-kWh rates are a bit higher. It’s the "predictable" option. I tell my neighbors that this is the plan for people who want to go solar and then forget about it. You won't get the absolute maximum savings possible, but you also won't get a $200 surprise bill because you hosted a dinner party on a hot Thursday evening.

The key to the Customer Generation plan is "Solar Offset." Since you aren't worried about demand spikes, your goal is just to produce as much energy as possible during the day to cover your total usage. However, SRP still uses a net billing system, meaning they only give you a small credit for the power you send back. I learned this when I looked at a neighbor's bill—he was producing 110% of his power but still had a $60 bill! Why? Because he was exporting all his noon sun for cheap and buying expensive grid power at dinner time. Even on the "safe" plan, a small battery or some basic load-shifting (like running the pool pump at noon) is the secret sauce to making the ROI work.

In the old days, a battery was just for "emergencies" or "off-grid" enthusiasts. But in 2026, if you’re an SRP customer, a battery is basically a financial tool. I look at my battery now as a "Peak Shaver." On the Average Demand plan, my battery’s job is to make sure my house never pulls more than 2kW from the grid during peak hours. If I turn on the vacuum while the AC is running, the battery kicks in and covers the difference. SRP never even knows I’m using that extra power. It’s a bit of a tangent, but I honestly feel like I’m "stealing" my own sunshine back from the utility company, and it feels great!

For those on the Customer Generation plan, the battery’s job is different. It’s an "Energy Shifter." It stores the 12 PM sun and lets you use it at 7 PM when you’re making dinner. Without the battery, you’re selling that noon sun to SRP for about 3 or 4 cents and buying it back for 13 cents. With the battery, you’re "selling" it to yourself for the full retail price. When I did the math for a client in Gilbert, the battery paid for itself 30% faster on an SRP plan than it would have on a "standard" utility plan. SRP’s complex rates actually make batteries *more* valuable, which is a funny irony if you think about it.

I’ve been seeing a new trend in Mesa and Chandler lately: "Zero-Export" systems. These are systems designed to never send a single watt back to SRP. Why would you do that? Because SRP’s export credits have gotten so low that some people decide it’s not even worth the paperwork to sell it back. Instead, they size their solar array perfectly to their daytime needs and use a battery to catch any extra. It’s the ultimate "energy independence" move. You aren't just a customer; you're a closed-loop system.

Is it right for everyone? Probably not. It takes a lot of careful planning and a very high-quality battery setup. But for the homeowners who are really frustrated with SRP’s fees, it’s a way to take the power back—literally. I always tell people to look at their "base load"—the amount of power their house uses just to stay alive (fridge, internet, clocks). If you can cover that base load with solar and store the rest, you can get your SRP bill down to just the basic connection fee. In 2026, that connection fee is about $32. Imagine a summer in Arizona where your biggest electric bill is thirty-two bucks. That’s the dream, right?
