Net Energy Metering 2.0, or NEM 2.0 for short, is now the law of the land, at least in SCE territory. So what does that really mean for potential solar clients? Here's the scoop...
NEM 2.0 brings three changes to how new solar clients will be treated by SCE (customers of PWP, LADWP, or any other muni utility are unaffected). Let's take a quick run through each one:
- A one-time application fee - new solar clients will be charged $75 as part of the interconnection application process. (In the past there was no charge.) Not a big deal, just another annoyance from SCE.
- Switch to Time of Use rates - this is a much bigger deal. Most residential customers are on a two-tiered rate structure with a "penalty" tier for users who exceed 4x baseline allocation. Under that rate structure the maximum cost for energy is 31.224¢/kWh.
Going forward, new solar customers will be charged based on when they use energy, not how much energy they use, with a Summer, on-peak energy cost of 44.665¢/kWh! Ouch! Peak hours are weekdays (holidays excepted) from 2-8 p.m.
- Non-Bypassable Charges - Under the old rules, energy that was imported from the grid could be entirely offset by energy exported onto the grid. Now, for every kilowatt hour imported, regardless of exports, the customer will pay a small (for now) non-bypassable charge of 2.25¢/kWh. Again, the utilities were pressing for this to be a much higher number, but for now this is a relatively minor surcharge.
So what does this all mean? The answer is, it varies. For some clients, particularly those with west-facing roofs, they may actually do better under TOU rates than they would have staying on the old, tiered rate plan. But to answer that question requires a proper analysis, and this is where potential solar clients need to do their homework and look closely at their solar bids.
Here's what to look for. Your potential installer should be requesting that you provide them with SCE's "interval data" for your home. This hour-by-hour data for the entire year allows for a proper analysis of your usage, and makes it possible to compare that historical usage with the modeled output of your proposed PV system. If they aren't asking for interval data, they are taking shortcuts with their savings analysis - likely in ways that inflate your potential savings on paper, only to result in disappointment down the road.
