Lessons: 1) Having an investor-owned utility with a shoulder at the wheel can get a lot done; 2) the anti-wind vibe might be weaker than it looks; 3) let's see what else we can do with the industrial capacity (the ship! the workers!) that Dominion has built with VA ratepayers' $$

Canary inbox: Coastal Virginia Offshore Wind (CVOW) is nearing completion off of Virginia Beach. That's 2.6 GW--the biggest offshore wind project in the country-- in the Southeast, projected to be online in the next 6 months. we likely have the tax credit sunset to thank for it!

Feels like market maturity didn't come a moment too soon for storage, which has become a serious player on some of our grids only in the last few years

Another shoe yet to drop: Data center load could really change the reliability dynamics for our systems, and AFAIK the big utilities (Southern/Duke) in the Southeast haven't re-run their reliability analyses with their shiny AI loads

Grateful to the FT for posting this. It shines an honest and unkind light on the rest of us.

When normal people read this graf, do they get a sniff of incoherence or hypocrisy? Or am I like way outta the mainstream consciousness on this?

Congrats to @wilson-energy.bsky.social and grid strategies on the 2024 data center load report--wanted to add add'l insight from looking at Georgia Power's quarterly large load forecast (s/o to Celia Tandon for putting this together!)

Derek Stenclik is smashing core paradigms of how we model the power system and fully demo-ing his results live on the zoom. He's just operating at a different level. Thanks to @gridlabenergy for bringing these insights to the world and derek for singlehandedly changing the game.

4/6 In PHIRA, we set out what we're calling "North Stars" for how utility plans can take advantage of the IRA, plus actions that regulators can take to make sure that ratepayers are actually getting the benefit of the legislation that we passed.

3/6 The challenge for us in the present is to effect that change. The IRA predominantly offers incentives, and it's up to us to ID the opportunities in the IRA and we take advantage of them. RMI worked with staff across the country to inform how we thought the IRA might show up:

Comparing UN Emissions Gap reports from 2023 and 2018 (2023 on the left). A few interesting things:
- Projected emissions for the most ambitious NDC case a little lower, but the gap to 2° still looms
- 2023 UNEP reports expects peak world net emissions in mid-2020s (!)
- Projected emissions for the most ambitious NDC case a little lower, but the gap to 2° still looms
- 2023 UNEP reports expects peak world net emissions in mid-2020s (!)

Last week, USDOE released their Liftoff report for VPPs and found that, by just 2030, 80-160 GW of VPPs could be online. For context , that's ~10-20% of the 2023 peak demand across the United States. In other words - VPPs will be a big deal. liftoff.energy.gov
