Long🧵on the provisions of #BuildBackBetter on all things #electricity & #grid. The act starts w/ ~3bn in loans for electric co-ops @NRECANews, incl. projects w/ #batteries. Co-ops have been very involved in @ENERGY-funded R&D & are now enabled to bring results to practice! 1/
It is funny that in my postdoc work @CMU_ECE & @NRECANews w/ @eeregov funding, we actually studied the added value of #battery to #photovoltaics for residential customers' energy cost savings: energy.gov/eere/solar/pro… & [1],[3], [4] here panay1ot1s.com/publications-s… 2/
Another ~10bn to co-ops for loans until 2031 to improve #resilience & #reliability w/ investments in #renewables & #transmission . Co-ops 'own' transmission lines & this money can motivate adjacent upgrades. Also critical that #renewables & #transmission appear together here! 3/
This comes from TX gov's letter to the local PUC in light of a stressed electrical #grid & it is so scientifically uninformed! A 🧵on #reliability in the #electricity sector... -1/n
Reliability is the behavior of an asset according to what is built to do w/o "breaking". Wind turbines & photovoltaics (WT+PV) are reliable when they generate according to blowing wind & shining sun. They are unreliable when a WT blade breaks or PV get hot-spots. -2/n
In other words WT+PV #volatility has nothing to do w/ reliability. Pushing the "volatility=reliability" narrative is unscientific, if not plain bad use of the language we all agree upon to communicate w/. -3/n
