California leads the nation in rooftop solar installations but has fallen short in creating a viable community solar market. Last year, Assembly Bill 2316 (AB 2316) unlocked the potential for California to lead the nation in community solar over the coming years by finally creating legislation that will tell the utilities to create a program that will credit customer’s accounts for renewable electricity produced elsewhere and set a compensation for the bill credit. Now, the utilities are attempting to derail a new proposed program called the Net Value Billing Tariff (NVBT).  

‍

The NVBT would finally allow California renters, nearly 17 million people, and low-income households to take advantage of bill savings while using clean energy. There are a couple of things that make the NVBT different from failed community solar programs in California. The first is that it would require the installation of batteries with community solar projects, to alleviate the strain on the grid during peak hours (currently 4-9 p.m.), once demand is higher and solar energy being exported to the grid is dropping off as the sun sets. The second is that AB 2316 requires that low-and-moderate income households make up a majority of subscribers, ensuring that this program will benefit those who are paying a disproportionate amount of income towards skyrocketing electricity rates. Finally, this program has no caps on capacity, meaning the doors are truly open for developers that want to build these projects.

One of the biggest advantages of community solar is that the solar power systems can be placed on rooftops and in parking lots, and the systems don’t require large plots of land like utility scale solar does. Community solar can also support local clean jobs and stimulate the regional economy. With the state’s target to procure 85 gigawatts of clean energy by 2035, there is already a large amount of projects in the desert trying to connect to the grid, however community solar projects can be a lot closer to the customers they serve, meaning they are able to connect to the lower voltage grid, eliminating the need for more costly and fire-causing transmission and distribution lines.    

‍

It is no surprise that the only arguments against a program that could potentially replace dangerous peaker plants comes from the state’s three investor-owned utilities. The main argument coming from the utilities is that community solar should be treated like large-scale generators that have a different set of rules and guidelines than other distributed energy resources like rooftop solar. 

‍

The California Public Utilities Commission proceedings tend to move pretty slowly, so there isn’t a definitive date for when we can expect the NVBT to be voted on by the commissioners. California has now passed the September 26 deadline for states to apply to $7 billion in federal funding as part of the Solar For All grants and having a community solar program in place would have made California’s application a lot more competitive.

While the utilities have successfully blocked attempts to make solar more accessible, including the decision to slash the state’s net energy metering program last year, hopefully the state can get it right on this one.
