Another very big bill signed. SB-254 has short-term, medium-term and long-term measures to improve affordability of electricity. I don't know what is the "official name", I like California Electricity Modernization and Affordability Act #energysky leginfo.legislature.ca.gov/faces/billHi...

AB-825 (nee SB-540), the Independent Regional Organization - Expansion of Day Ahead Market was signed by Gov. Newsom Awesome! After so many attempts Western States together leginfo.legislature.ca.gov/faces/billHi... #energySky

RE+2025 happened last week and I tracked news on residential electrification I liked best ConnectDER IslandDER: a <$850 Meter Socket Adapter with a MID and CTs to integrate whole-house batteries. ConnectDER PR listed 4 vendors, including FranklinWH and EcoFlow, and they have 22 more... #energysky

These are the last days of the California Legislature An overview of key energy bills is at pelegri.substack.com/p/summer-rec... I just got mail from a group that should know better with misinformation about SB-540, the Extended Day Ahead Market. My take is at pelegri.substack.com/p/electrical...

Does anybody have pointers to / experience with Real Time Pricing tariffs in Spain? I'm looking into the proposals for California and I'd love to do a compare / contrast. I know what the rates are, what I'm looking for is customer feedback #energysky Compared to California's proposal...

The @californiapuc.bsky.social is discussing when & how to bring real-time pricing. The rates used in the PG&E Pilot show fairly low rates with narrow spikes & moderate peaks. A household can handle them with a residential battery to save money and help the grid pelegri.substack.com/p/the-shape-...

Want to know why it's so goddamn hard for utilities and battery project developers to do what might seem at first glance to be the relatively simple task of installing a battery to be a stand-in for grid upgrades? Check this out: www.latitudemedia.com/news/inside-... #energysky

California promised dynamic rates back in 2001 but they are not yet widely available even after spending $4.5B of ratepayers money in Smart Meters. New legislation AB-1117 wants to change this open.substack.com/pub/pelegri/... #energysky

Best practices for tracking changes to (energy-related) bills in the California Legislature: subscribe to the bills on leginfo, use Compare Versions, and read the bill analysis from the committees. A bill can change in any way at any time #energysky Today's change: AB-1273 now clarifies...

Money from California's Cap and Trade auctions are reimbursed to customers as Climate Credits. There are 3 bills in the legislature proposing changes to best benefit those customers that need the help the most Check pelegri.substack.com/p/your-elect... #energysky

Californians are tired enough of high electricity rates that SB-332, an investigation on whether we can switch OUT of Investor-Owned Utilities, keeps moving through the legislature leginfo.legislature.ca.gov/faces/billVo... It will be *very interesting* if it ends at Newsom's desk #energysky

Somehow I missed that California's AB-306 was subsumed into AB-130, which was approved and signed by our Governor on June 30th AB-306 was a moratorium on housing code changes, and AB-130 is an omnibus bill to encourage housing #energysky

A good, approachable, description of the financing issues behind our high rates. Here in California SB-254 is trying to fix several problems including financing and wildfire costs.

What city in the USA will be next to impose congestion pricing? Hopefully most of them and they'll have EV discounts so that we can transition away from this subsidy model that is NOT working well enough. 🔌💡

CPUC approved last week a decision on R.19-01-011 regarding service line upsizing, including non-isolating MSA (meter socket adapters) I just pushed out a note on the basics of a Voting Meeting and on how I used CoPilot to digest the decision #energysky pelegri.substack.com/p/meter-sock...

@californiapuc.bsky.social I support your efforts to encourage public participation in CPUC proceedings. It would help *A LOT* if you switched to a modern participation platform. At the least provide recordings on YouTube -- that gives transcript automatically. Ideally... #energysky

This proceeding supports Meter Socket Adapters, Watt Diet and other measures to help electrify buildings #energysky

Today we continued efforts toward meeting California's climate and equity goals by approving measures to accelerate the transition to all-electric buildings. Read more: docs.cpuc.ca.gov/PublishedDoc...

If you are considering adding a residential battery, or just interested in the topic, I just published a note covering six vendors. pelegri.substack.com/p/modern-res... I now see a battery system as the core of a house microgrid #energysky

This can be a big session for energy here in California. Another good bill is moving forward. Sen Beckers, Wahab et al) SB-254 If it passes the Assembly and its signed by Newsom it can deliver short-term, medium-term, and long-term affordability benefits #energysky

More amendments to SB-540, the California bill creating an extended day ahead market (EDAM). Next is the Senate Floor. We need EDAM for affordability, resilience and renewables #energysky Earlier post pelegri.substack.com/p/electrical... Changes leginfo.legislature.ca.gov/faces/billVe...

AB-942 (California Assembly) is a bill debating NEM in California. I'll skip on the debate on "True Value of Solar" but... it just went through Appropriations with a label of "no budget implications" BUT! #energysky if AB-942 passes it will mean that the @californiapuc.bsky.social will have...

I felt I needed to learn more about the California PUC as they play a key role in California's Energy Transition. My first "Regulation" post collects what I learnt about the CPUC Proceedings pelegri.substack.com/p/intro-to-c... #energysky

@californiapuc.bsky.social Nice to see you here I see you posted news of the RCPPP workshop at both FB and LinkedIn but I can't find the announcement here. BlueSky is better because it is time-ordered and it is easier to follow I missed the workshop but I'll catch up in the video #energysky

Peeling the onion... The more I understand the California Electrical landscape the more nuances I see. Now tracking SB-326 (California Wildfire Mitigation Strategic Planning Act) b/c most of our rates are from Transmission and Distribution, and Wildfires are a big part of that #energysky

BPA, the Bonneville Power Administration, is the administrator of 31 hydroelectric plants in the NorthEast (~22.4 GW). BPA is currently part of the real-time WEIM market, run by CAISO. BPA just confirmed its intention to join Markets+ Day Ahead market from SPP instead of EDAM... 1/2 #energysky

Implementing a Distributed Capacity Procurement that installs solar&storage on distribution circuits to dramatically increase capacity on existing circuits at 1/10th the cost. Their customer subscription model is an interesting way to reduce friction. www.prnewswire.com/news-release...

Georgia Power signed a big contract with LineVision to deploy dynamic line rating to their entire footprint. www.linevisioninc.com/news/linevis...

During today's AB-942 bill, the proponents repeatedly said that NBT compensation is 76-82% of NEM 2.0. Anybody has any idea where that came from? Because my numbers are very different. #energysky docs.google.com/spreadsheets...

Ha! I had no idea that Meter Collars had been around for a long time. Just bumped into this from Marwell Corp from 1979. marwellcorp.com Marwell manufactures the Renewable Meter Adaptor for SDGE. I am writing a blog post on collars. It's fun content #energysky

I'm attending (remotely) my first CPUC workshop. This is on scenarios for High DER adoption. Current presenter is from Minnesota PUC on their own plans (Xcell dominated). Good experience attending so far. Unravelling the collection of proceedings at CPUC site was hardest part

The California Senate Energy, Utilities and Communications Committee has hearings today. Bills covered include SB-540 (Regional Day Ahead Market in the West), SB-541 (Load Shifting), SB-332 (IOU Accountability), SB-836 (Transmission planning and permitting) and mroe #energysky

I just noticed that Enphase has started making noises about new products: a new battery 10C with more storage and fewer microinverters, a new combiner and a new meter collar. They are beginning to look competitive in the storage space, and their batteries are made in the US... #energysky

In case it wasn't already clear: new US nuclear is highly unlikely to scale in time to meaningfully support AI load growth over next 10yrs, from large or small reactors. I wish it wasn't the case, but this is reality. If all goes well, we'll have ~handful of SMRs online by 2035.

I finished a first pass through a list of Energy-related bills in the California 2025-2026 Legislature. Let me know if you think I missed an important bill. Caveats - the bills can change a lot, and can do at any time. pelegri.substack.com/p/energy-bil... #energysky
