NYT on the importance of transmission, with a quote and cite to me: https://t.co/Um062UtwgQ

The current system makes it hard to build the long-distance power lines needed to transport wind and solar nationwide.

New reports coming out next week: Energy & ancillary market reforms are needed in MISO and PJM to level the playing field and allow wind, solar, and battery storage to fairly compete and utilize their full capabilities. Link to register: https://t.co/TORPHwa9t3

Great article discussing the game-changing provisions in legislation being proposed today to facilitate paying for and permitting electricity transmission, which Grid Strategies estimates will reduce CO2 emissions by hundreds of millions of tons per year. https://t.co/YBvQpaXfOa

Power lines are crucial to expanding renewables. America could finally—finally!—be about to build more of them.

Pass that Motion to Proceed to a bright future on a livable planet! PS, happy to give the Veep a ride if she needs one. Not a problem, her house is right on the way there for me.

@AlexEpstein Wind provides 32% of the electricity for the grid operator in Oklahoma, Nebraska, Kansas, and neighboring states, and power prices there are low and getting lower. Add solar, and our existing nuclear and hydro, and 80% is easy.

Southwest Power Pool South Hub power prices increased 8.8% year on year in December, following rising gas prices on colder weather, as wind powered generation became the lead fuel source for 2020, a f

#transmission planning is SO important and we KNOW how to do it but it isn't happening? Reasons? Read this report. Solutions? Read this report. Want action? Send a comment in to @FERC in docket RM21-17 by Tuesday. Thread. 1/8

With better transmission interconnections to neighboring states, Texas could have saved around a billion dollars in winter storm Uri in Feb. 2021. Similar findings in other regions: more transmission = millions in savings through bad weather. https://t.co/7HR2w6vl6B

Expanded inter-regional #transmission is essential for delivering a lot of energy across large parts of the country, especially during many difficult-to-predict situations. Read @RobGramlichDC's piece in @UtilityDive here:

“Extreme weather poses risks to the grid that require smart and urgent investments to reduce blackouts and brownouts. Together, we must build back better an electric grid that’s cheaper, cleaner and more reliable.”
All Americans are watching the situation in Texas and throughout the heartlands with great sadness. We must come to the aid of those suffering without power and water, and we grieve with the families who have lost loved ones to this disaster.

Transmission aggregates diverse sources of electricity supply and allows imports when extreme weather takes local generation offline. For the same reason, we can decarbonize reliably and cost-effectively using transmission to access diverse wind and solar. https://t.co/VAKNB8JsfP

Modeling correlated outages would show the value of generation diversity. If your power system is half gas capacity, like ERCOT's, adding more gas provides diminishing returns for reliability. All energy sources can be disrupted, so being too dependent on any one isn't wise.

For more on accounting for correlated outages in reliability and generation investment planning, researchers analyzed 2 million outages and found “correlated failures represent a significant resource adequacy risk” in most regions. https://t.co/9FA1zpJGhj

It sounds like around half of the gas fleet in ERCOT is also offline, leading to the rolling blackouts there. Probabilistic generation planning tools can account for correlated outages. We use them to account for correlated output profiles of wind or solar, but not fossil.
Confidential info from a market participant in ERCOT: As of ~10 AM Eastern time, the system has ~30 GW of capacity offline, ~26 GW of thermal -- mostly natural gas which cant get fuel deliveries which are being priorities for heating loads -- and ~4 GW of wind due to icing.

Now over 50% of SPP’s gas capacity is offline, leading to rolling blackouts. When utilities try to justify building gas plants they don’t account for these correlated outages, despite nearly a dozen events like this over the last decade. If they did new gas wouldn’t look good.

This weekend 30-50% of gas capacity in Southwest Power Pool, or 10-15 GW, has been on forced outage. Luckily wind has been providing 15-25% of total electricity, with only 15% of the wind fleet on outage. A few GW of coal and diesel are also offline. https://t.co/CRi9dHob6E
There is a well-documented history of gas plants experiencing simultaneous outages during winter storms, both because of supply disruptions and freezing equipment. Our expert @gogginmichael laid it out.
