The CPUC insists it wants people to add batteries to solar systems to help the grid. But it just cut the compensation that households can earn by doing it.
Seriously, leaving that part out defeats the purpose of the article. News media is so up their own ass (and by extension, their republiQan overlords’ asses) that they refuse to speak the words that matter.
Rates were rising for low-income people who would never have been able to avail themselves of these incentives partially as a result of some of the incentives. Requiring utilities to buy the electricity at the same rate they sell it at, rather than the commercial rate, was never going to be sustainable in the long-run without causing massive cost increases for those who can afford them the least.
Yes, but this is about an additional cut - for the few hours per year when having additional power from peoples' batteries means that no new generation capacity is needed. Avoiding those costs benefits everybody, and deciding not to compensate folks for it isn't a good move.
I write this from a place where electricity is provided by a crown corporation (government ran corp - SaskPower) and also have a net-zero rooftop solar system, and small scale solar like this is quite inefficient compared to grid-scale stations. I very much agree that there is some sovereignty in producing one's own power, however, grid-scale generation is much more effective, both in cost and generation efficiency.
SaskPower has really had no recent incentives for rooftop solar and they only pay about half price for power returned to the grid, effectively discouraging widespread development of rooftop solar.
They have instead proposed an interesting alternative where a homeowner could purchase a portion of a larger scale facility and be credited for the electricity that portion generates. Crowd-funded electricity generation, essentially. This is, of course, much more attractive when the provider is essentially a company owned by the public, not a private, profit seeking entity. But, I think it could be a promising alternative to enable homeowners to offset their electricity bills while being a better option for the overall grid.
Larger scale is cheaper, but rooftop avoids the need for long-distance transmission [in short supply right now in California] and limits the need to convert farmland into solar
That's true. The system can be far more robust if its decentralized. Even living in a place with cheap electricity I still plan on getting panels in the future.
A couple things to add to sonori's reply, the system efficiency also goes up when you can use higher capacity inverters. Essentially, one grid-scale facility (say, 100 MW) will have far fewer inverters than 100 MW of rooftop systems, meaning less efficiency loss.
While larger facilities can be optimized for azimuth and sun angle or with tracking, rooftops are often not optimally aligned, leading to a decrease in capacity. Sure, you could add tracking to your residential system, but that's a significant cost that many homeowners won't see the benefit of. There might also be obstacles that shade a residential system, which is often addressed when selecting sites for larger systems.
it should be illegal to generate power on residential or commercial parcels. California is doing the right thing by disincentivizing it. Large, privately owned, power providers can self-regulate which then regulates all production
it's good for everyone except the rich and greedy who can afford their own rooftop array
You're confusing upper-middle class with rich. Also, many middle class people finance their rooftop solar and these incentives make it more affordable.
