Imagine my displeasure when I +started doing the math on some of my recent power bills. Where I live Pacific +Gas and Electric (PG&E) is the predominant utility company but fortunately I am +also able to purchase electricity from [Sonoma Clean +Power](https://sonomacleanpower.org/). Nevertheless, I still receive a bill +from PG&E which is the owner/operator of most if not all of the transmission +and generation capacity in the region. In Northern California there is no love +lost for PG&E, which has been found responsible for negligence leading to +numerous wildfires, gas pipeline leaks, and explosions. Much of this negligence +has been due to postponing of forfeiting maintenance in order to recognize +higher profits. To add insult to injury, it seems like they skim a healthy +margin off of residential producers/consumers as well. + +In 2019 I installed solar panels on my roof, and then waited for over six +months for "permission to operate" because the transformer the house connects +to was too old. That's another story, but a common one among a long list of +deferred upgrades by the company. Once we gained permission to operate, our +rate plan switched over to "time of use" with [Net Energy +Metering](https://news.energysage.com/net-metering-2-0-in-california-everything-you-need-to-know/). +In essence, I pay a variable energy price depending on pre-set off-peak and +peak energy rates, and my solar generation can offset the cost of non-solar +power used. + +This "time of use" type plan has [rates +defined](https://www.pge.com/en_US/residential/rate-plans/rate-plan-options/time-of-use-base-plan/time-of-use-plan.page?) +for winter and summer periods. The current summer rates for me result in **$0.35** +per kilowatt/hour (kWh) off-peak, and **$0.42** per kWh during the peak period from +4pm to 9pm. + +It is quite obvious why peak power costs more, there's a *lot* more demand in +the summer afternoon for air-conditioners, etc. I would hazard a guess that the +peak doesn't start earlier because of a surplus of solar power as the sun is +directly overhead from 12-2pm. + +The power generation prices that **I** am paid however for generation are +**$0.07** for off-peak and **$0.13** for peak generation per kWh. That means I +have to generate _three times more power_ during peak and _five times more +power_ during off-peak in order to break even. + +I am a retail consumer of electricity but a wholesale producer. + +--- + +In 2020 California's largest production of electricity was from natural gas +power plants [according to a California Energy Commission +report](https://www.energy.ca.gov/data-reports/energy-almanac/california-electricity-data/california-electrical-energy-generation). +photo-voltaic solar (panels) were the _second_ largest class of electricity but +only produced 1/3 as much energy. California imported almost as much from other +states as our own natural gas facilities produced, 81gWh compared to our 92gWh. + +In my opinion solar and wind production need to grow and the best way to +encourage that behavior is with better rates for clean energy production and +poorer rates for carbon-producing ones. The California Public Utilities +Commission has the power to influence this behavior, but who knows whether +they're willing to step up. diff --git a/tag/solar.md b/tag/solar.md new file mode 100644 index 0000000..7de7496 --- /dev/null +++ b/tag/solar.md @@ -0,0 +1,6 @@ +--- +layout: tag_page +title: "Tag: solar" +tag: solar +robots: noindex +---
