Net Metering 3.0 Rules Create Chaos In Rooftop Solar Market In California

The issue with insurance policies is that they will change. For years, California has had a coverage in impact that required utility corporations to compensate householders and small enterprise house owners for any electrical energy they exported again to the grid from their rooftop solar systems. However there’s such a factor as an excessive amount of of a very good factor. California has been a pacesetter within the clear vitality vitality revolution for many years, however as we speak it has a lot solar energy out there — particularly within the late afternoon when the solar is the strongest — that a lot of it’s wasted. It’s both given away to those that will take it or despatched to floor.

Most CleanTechnica readers are conscious that the utility trade has been overtly hostile to rooftop photo voltaic ever because it first turned out there. For one factor, it disrupts how {the electrical} grid is structured — one or two central producing stations that feed electrons out to the group by way of a collection of substations. It was by no means meant to be a two-way avenue, and accepting electrical energy from the margins of the grid precipitated structural points that utilities would relatively keep away from.

However there’s extra to it than that. For greater than 100 years, most utility corporations have been investor-owned, for-profit enterprises that had been granted unique rights to offer electrical energy inside a specified territory. It annoys them to no finish when others attempt to horn in on the monopoly. Their common perspective is “We have the exclusive right to provide electricity in this market and we will do everything we can to keep from sharing our rights with any interlopers!”

The factor about photo voltaic panels is that anybody can set up them and make their very own electrical energy. How dare they! It was by no means doable for particular person householders to construct their very own thermal producing station or nuclear energy plant. Rooftop solar results in the democratization of electrical energy and that’s anathema to the utility trade. Why, earlier than it, one individual could get the wild concept to share a few of that rooftop photo voltaic electrical energy with a neighbor after which the place will we be?

Web metering is the engine that has pushed the rooftop photo voltaic trade since its inception. Placing photo voltaic panels on the roof isn’t low cost, even with varied federal and state incentives. The cash the utility corporations needed to pay pursuant to numerous internet metering schemes went a great distance towards making rooftop photo voltaic reasonably priced for a lot of, particularly low-income households for whom the month-to-month electrical invoice was a big a part of their family finances.

An Earthquake In Rooftop Photo voltaic

Final 12 months, the California Public Utilities Fee (CPUC), with the energetic assist of the state’s largest investor-owned utilities, eviscerated the prevailing internet metering laws. The new planoften called NEM 3.0, slashes the quantity the utilities must pay their rooftop photo voltaic prospects by 75 %. Ouch! In consequence, purposes for brand new rooftop photo voltaic programs skyrocketed, as folks sought to get in on the gravy earlier than the brand new guidelines went into impact. After NEM 3.0, purposes fell by about 50 %. Since then, a number of massive rooftop photo voltaic corporations have gone bankrupt.

The CPUC justified the change by saying the state wanted extra batteries to take in electrons in the course of the day and ship them again to the grid within the night and actually the variety of residential batteries put in in California has jumped. However batteries are costly and add fairly a big quantity to the overall price of a rooftop photo voltaic system. The quantity the utilities now must pay to entry that saved electrical energy is hardly sufficient to justify the added expense, however it could actually decrease utility payments if self-consumed by the home-owner.

In keeping with CNET, NEM 3.0 created vital challenges for photo voltaic companies. Photo voltaic Insure, a photo voltaic insurance coverage firm, says that 32 photo voltaic companies in California closed their doorways in 2023 and 2024. Amongst these had been well-known prime photo voltaic corporations like ADT Photo voltaic. These closures had ripple results. The California Photo voltaic and Storage Affiliation reported a 22% decline of photo voltaic jobs in California, equating to 17,000 fewer positions by the top of 2023.

Rooftop Photo voltaic Plus Battery Storage

The affect on residential storage batteries has been dramatic, nonetheless. Berkeley Lab experiences there was a 50 % improve in battery storage attachments — the coupling of a storage battery with a rooftop photo voltaic system — since NEM 3.0 went into impact. Vincent Ambrose, chief industrial officer of photo voltaic battery producer FranklinWH, mentioned the affect could also be extra dramatic than that. His firm’s knowledge signifies attachment charges have been 90% to 100% since NEM 3.0 began. “This increase is not only a good thing for battery companies — it’s good for the energy grid and homeowners wanting to secure their energy resiliency,” Ambrose mentioned.

Carina Brockl, chief income officer at Aurora Photo voltaic, mentioned NEM 3.0 initiated a steep studying curve for installers to successfully design and market photo voltaic plus storage programs. “Although battery costs are decreasing — making them increasingly beneficial — the industry had previously considered the economic viability of combining solar and storage to be several years away. NEM 3.0 has expedited the feasibility of battery technology in the market.”

Whereas battery costs could also be happening, rising rates of interest precipitated home-owner curiosity in photo voltaic plus storage to drop as contract costs elevated considerably, Ambrose mentioned. “This, along with the rising interest rates and installer bankruptcies forced financing companies to tighten lending guidelines. As a result, solar installers faced liquidity problems, leading to bankruptcies.”

Lawrence Berkeley National Lab has been trying on the knowledge since NEM 3.0 went into impact, and whereas it confirms that extra photo voltaic plus battery installations are happening, it says the common price of these programs have spiked by 17 % over final 12 months. It’s the outdated provide and demand conundrum. Immediately everybody needs a battery with their rooftop photo voltaic system however there aren’t sufficient batteries or skilled installers to fulfill the demand. Due to this fact, costs have gone up, one thing the CPUC appears to not have taken into consideration.

Microgrids and Digital Energy Crops

The upshot of the brand new guidelines is that fewer prospects are sending electrical energy again to the grid as a result of the financial incentives to take action are merely not there. California wants a strong system of digital energy vegetation just like what Green Mountain Power is doing in Vermont, however the brand new guidelines don’t do sufficient to encourage VPPs, says Canary Media. That’s one other factor the CPUC did not adequately take into consideration.

As well as, the state and the utilities appear to have completely ignored the chances of vehicle-to-home (V2H) know-how. California has extra electrical automobiles per capita than every other state. The batteries in these automobiles may simply kind the premise of a wider microgrid that will enable utilities to retailer extra solar energy in the course of the day. As an alternative of these corporations shopping for grid-scale batteries, they might lease some portion of all these batteries and mix them into microgrids that function demand response methods to kind a lot of native microgrids.

Any CleanTechnica reader could be completely satisfied to advise the utilities and the CPUC methods to devise a complete plan that focuses on the long run relatively than insurance policies that had been out of date years in the past. What the CPUC has completed is create chaos. The residents of California deserve higher.
