Snapshot of Load Changes, California (CAISO) and New York City regions (NYISO NYC): an Addendum

LCG, April 6, 2020 -- Jeremy Platt, Palo Alto has made some additional observations of impact of COVID - 19 on electricity demand using the grid operators data published by LCG. This note extends the results reported on March 27, 2020. The magnitudes of load reduction are very different due to the different sizes of these regions, but the times and scales of sharp reductions of ~ 16% are remarkably similar

California PUC Targets Doubling Renewable Energy by 2030

LCG, March 27, 2020--The California Public Utilities Commission (CPUC) yesterday unanimously approved a new emissions target for its electric sector that would double California's clean energy capacity through 2030 and effectively block new natural gas-fired electric generating facilities.

Nuke Corrosion Costs Burden Ohio Plant

LCG, March 26, 2002-Investigations regarding regarding reactor corrosion may keep nuclear plants shut down.

Boric Acid in an Ohio nuclear plant corroded the cap of the reactor, forming a significant hole.

The Nuclear Regulatory Commission (NRC) ordered that 69 pressurized water reactors be inspected after the hole was found in the 25-year-old David-Besse plant. Special attention will be given to the six reactors sharing the same Babcock and Wilcox construction as the David-Besse reactor.

The damaged reactor will take three months to two years to repair, depending on whether or not a new reactor head will need to be constructed. In the meantime the plant will be forced to pay ten to fifteen million dollars monthly to buy power in order to sustain its 7 percent of company FirstEnergy's total energy. Repairs will cost at least $10 million and replacing the head would cost $20 million.

Midwest wholesale power prices for deliveries next summer increased by twelve percent last week, possibly caused by energy traders who fear limited energy supply.

Corrosion has been found in reactor nozzles of other plants, but none of the damage is nearly as serious as that at the David-Besse reactor. Plants and generators anxiously wait for inspectors from NRC to approve their reactors.

Officials say corrosion of this type poses no public risk.
