Sad to see coal going up (?)

toomuchtodo•1h ago

> In 2025, coal composes just 15 percent of U.S. electricity generation, and while 190 gigawatts (GW) of coal capacity remain online, the fleet is down 43 percent from 340 GW at its peak in 2010. This change is largely due to the fact that coal power is simply more expensive than cleaner power sources like wind, solar, batteries, and natural gas.

> Electricity demand growth and new actions by the current U.S. presidential administration may slow this decline in the short-term, but with no proposals to build new coal plants anywhere in America and worsening economic competitiveness – particularly where policymakers are strengthening air and water standards to protect their constituents – its long-term share of U.S. electricity generation will continue to decrease

The chart defaults to ending at 2025. Move the right timeline marker all the way to the right (today).

Utah isn't a power grid.

They're on the western interconnect.

Combined solar and wind are about 25-30% of production there.

These articles about individual states are trash.

Utah is about half of the Pacificorp East balancing authority.

Nevada Power serves a substantial amount of western Utah.

Cool, that's still not a grid for stability purposes.

can you expand? I'm not sure I get it. isn't then having a wider interconnection better for stability and to handle solar? they can share cheap power in gluts and pull in other sources at night and so on.

> Balancing authority (electric): The responsible entity that integrates resource plans ahead of time, maintains load-interchange-generation balance within a Balancing Authority Area, and supports Interconnection frequency in real time.

> Definition & Scope: A BA is a NERC-certified entity responsible for matching electricity supply and demand in real-time within a specific geographic area. An ISO is an independent, non-profit corporate entity that manages regional transmission grids and runs competitive wholesale power markets.

A balancing authority is quite literally a federally certified entity for maintaining grid stability.

Also true for California for quite some time.

What's going to happen in the future is that May will be a month of extreme electricity abundance, with a good chunk of the electricity just not being collected at all because the grid doesn't need it, and it will be cheaper to have unused electricity in May than to have too little solar in December.
