BATTERY SYSTEM CAPITAL COSTS, OPERATING COSTS, ENERGY LOSSES, AND AGING

Grid-scale Battery System Owning and Operating Cost for Solar Bulge Control

 

Battery systems perform various functions during a day, including absorbing the heavily subsidized, midday solar output bulge, and discharging about 81% of it during the peak hours of late-afternoon/early-evening; the other 19% are system losses. See Part 4

 

Assume, in the morning, the batteries are charge at about 20% full, so they can absorb the bulge to about 80% full.

On many days, there is enough bulge to charge the batteries

In New England, panels are often covered with snow and ice in winter. 

On days, with little or no bulge, the batteries are charged with low-cost, night-time electricity

 

Assumptions for Analysis

 

- Bank loan 50%; Owner stake 50%.

State governments require investors to have a 50% stake in projects, i.e., “have skin in the game”

- Li-ion systems at $500/kWh for 2023. See Part 1  

- Capacity factor of 0.6

- Bank loan, 6%/y for 15 years

- Owner's return on investment, 9%/y for 15 years

- Cost of government subsidies at 50% of total costs

- System loss at 19%, HV AC to HV AC basis. See Parts 2 and 3 

- System aging at 1.5%/y is ignored. See Part 7

 

The 0.30 c/kWh of throughput is significantly understated, because it is based on a very high CF = 0.6, and excludes the cost of system aging

 

All project costs are paid by ratepayers, taxpayers, and added to government debts.

NOTE: Utilities of grid-scale battery systems have the real owning/operating numbers, which they do not make public, because they are “proprietary”

Do you actually believe that a political party that has no problem arresting its top opponent and his lawyers would have any problem stealing the election?

The people are going to find out that the 2020 election wasn't just stolen, but that these people worked with foreign governments to overthrow our government. When you have a puppet government in place, look what they do to the country, they destroy it.

Donald J. Trump - Truth Social post August 23, 2023

For the first time in three years, brave American Patriots will be able, in Court, to show how the Presidential Election of 2020 was RIGGED & STOLLEN. For those RINOS, Radical Left Democrats, Communists, Marxists, Fascists , & others who say, “Don’t Look Back, Look Forward,” they either do not want to reveal the answers because they “got away with murder,” or are FOOLS & COWARDS because we now know the answers to all of the Fraud, Irregularities, & Cheating, & WE CANNOT LET IT HAPPEN AGAIN!
