What Will Data Centers Do To Your Electric Bill? The threat of increased rates is real, but good policy can bring lower prices as demand grows. Electricity has recently replaced eggs, beef, and gasoline as the inflation concern du jour. Reporters…

My EI blog post today on how data center demand growth may drive up elec prices in near term, but managed well, should help lower retail price. Regulators must assure data centers reduce demand when grid is strained and pay fair share of system fixed costs.

Utility Regulation Really Sucks Podcast Episode Β· Shift Key with Robinson Meyer and Jesse Jenkins Β· 09/10/2025 Β· 1h 7m

Outstanding episode of Shift Key. Jesse Jenkins & Rob Meyer explain transmission & distribution remain regulated monopolies and challenges regulating them. Only quibble with idea incentive regulation substantially improves outcomes. It creates its own distortions.

Reining in California’s Runaway Electricity Rates We’ve led the nation in rate hikes. Now we’re test-driving some affordability fixes. National headlines are warning of an energy affordability crisis, with electricity rates cast as a primary culpr…

In the Energy Institute blog, Meredith Fowlie is out today with an important analysis of California's legislative accomplishments on electricity affordability as the session wrapped up last week.

Column | Can’t put solar panels on your roof? Plug-in β€˜balcony solar’ may be for you. Balcony solar promises to cut energy costs and grid reliance for renters and apartment-dwellers. I did a trial run at my home.

Lots of balcony solar discussion these days. Interesting idea but price in US is still much higher than grid scale. At 3% discount rate and 15% cap fac, the 200W system mentioned has LCOE of $0.13 if it last 25 years, $0.22 if it lasts 10 years.

Northwest U.S. natural gas prices remain historically low in 2025 - U.S. Energy Information Administration (EIA)

I've been asking questions about the low natural gas prices in the Pacific Northwest. Today, EIA has a great piece with many answers. It's the imports from Western Canada, where prices are even lower. Gotta love those benefits of international trade...while they last.

EI resident energy effic label expert, Lucas Davis, has great post today on fuel effic labels for EVs. I think he is too easy on them: annual cost estimate is based on US avg elec price, but they vary far more across states (3x+) than gas prices do.

CPUC Approves Guidelines for Large IOUs’ Dynamic Rate Designs The California Public Utilities Commission (CPUC) approved guidelines for utilities to use to design dynamic electricity rates.

Two useful RTO Insider articles on dynamic pricing in California. The CPUC wants IOUs to step up commitment to it, but the biggest municipal utilities are backing away from it.

Trump pardons Silk Road creator Ross Ulbricht Trump said he had called Ulbricht's mother to let her know he had granted her son a full pardon.

Given the trump administrations killing of 11 alleged Venezuelan drug dealers at sea today, now might be a good time to recall his pardon of a American drug dealer actually convicted of running a large drug operation and soliciting murders for higher.

Isn't it time for a constitutional amendment eliminating presidential pardons? In theory, they could be used to the benefit of society, but in practice they are a giant open door to corruption and authoritarianism.

If I am reading correctly the California Energy Commission's agenda for Friday's meeting, it looks like they are officially backing off the idea of a refinery margin penalty/tax. A wise move. It is impractical and doesn't target the true downstream problem.

Very interesting extended piece on the increasing flexing of France's nuc power to accommodate renewables', primarily solar, output variation. Sounds like can flex much faster than people generally acknowledge in US, but "thermal stress and corrosion remain concerns".

EIA data lag BLS on electricity, but through May 2025 not much sign of residential affordability crisis outside of CA in EIA data, CPI-adjusted. Many recent reports of rate increases and capacity price increases, so that could change, but non-CA May 2025 real elec price lower than 2014.πŸ’‘πŸ”Œ

The Puzzle of Low Data Center Utilization Rates Contrary to popular belief, data centers aren't maxed out around the clock - and this has real consequences for power system planning

@tnorris.bsky.social is one of the most insightful and creative people thinking about the impact of data centers on the grid these days. His work suggests that this is a very solvable problem, primarily through demand flexibility.

AI demand drives record electricity supply costs in largest US market Blow for Donald Trump’s vow of lower prices as grid operator PJM forced to pay 10% more to meet soaring energy needs

Data centers are driving up wholesale electricity prices. But surprisingly little coverage of potentially offsetting impact: spreading T&D and other system fixed costs over more kWh could lower retail prices. Wondering about net outcome from these two effects. πŸ’‘πŸ”Œ

Could California prevent more blackouts by joining a Western power market? The state built a clean grid. Now lawmakers are eyeing opening its market to states that rely on coal. Critics say it’s a risky bet.

Despite the tilted opening, this is actually a pretty balanced and informative piece on the state of California's legislation towards western electricity market regional cooperation.

The Netherlands seems to be becoming a cautionary tale for issues that can arise when electrification policy is not accompanied by sufficient supply planning or demand flexibility. Would love to see the low duration curve. Wonder if real crunch is < 40 hours per year.
