![]() If you take an average house using 10,000 kWh per year that has a 100% energy offset for the year and has 40% self-consumption, then 6,000 kWh will be exported to the grid. We’ve estimated that a PV system which offsets 100% of the homeowner’s energy usage will still end up exporting 50-70% of those kWh to the grid during the day, and the house will buy that energy back during the off hours. The yellow export section used to be valued at 9.2 cents per kWh, and now it’s down to 5.9 cents in the summer, 5.6 in the winter.Ĭustomers who export energy will see less credits for that portion of power, and therefore reduced bill savings. ![]() The green section is energy that the solar system produces during the day and offsets any energy being consumed at that time. From this we can subtract the credits they receive for any excess energy their solar panels produce (yellow). First is the sum of all the charges they accrue (blue). The biggest change to the net metering tariff in Rocky Mountain Power territory is that excess solar energy exported to the grid – shown in yellow in the chart below – receives lower compensation than before.Ī homeowner’s bill can be divided into three parts. What has Changed after the Rocky Mountain Power Credit Cut? Understanding your customer’s actual load profile and increasing self-consumption will give better outcomes. The low export rate makes selling excess PV energy less beneficial to the financial bottom line.This isn’t great for company bottom lines The best customer value may no longer be at 100% energy offset, but closer to 60%.Residential solar is still viable in Utah, but the value has been substantially reduced.In this blog post, we crunch the numbers to see if solar is still feasible in the beehive state. This change is applied to new customers going forward – those with existing systems will still continue to enjoy a fair export rate. This was a fair deal for a while as it was pretty close to the retail rate.Īt the end of October 2020, Utah’s Public Service Commission (PSC) granted a Rocky Mountain Power request to reduce that export credit from 9.2 cents per kWh down to 5.6-5.9 cents per kWh, seasonally adjusted. Rather than compensating solar production at the full retail rate (typically 8.8 – 11 cents per kWh for residential customers), owners would get paid a flat 9.2 cents per kWh for their exports. Rocky Mountain Power in Utah is one of the utilities that offers a NEM alternative in their transitional tariff. Recently, however, some utilities have begun removing or changing NEM policies, either by modifying the credits provided or by trying to remove net metering altogether. Net metering (NEM) policies, which provide customers with credits for excess electricity produced from their home’s solar panels, have been important in spurring the adoption of PV systems.
