GRID-SCALE BATTERY SYSTEMS IN NEW ENGLAND TO COUNTERACT SHORTFALL OF ONE-DAY WIND/SOLAR LULL
Wind Systems Paired with Grid-Scale Battery SystemsGrid-scale battery systems are increasingly paired with wind systems to reduce the adverse effects on grid stability, due to the variability of wind output, MW. During gusty wind conditions, the output of a wind system has large variations, which could adversely impact the stability of frequency and voltage of the grid.
For example, a utility, or grid operator, may require a 30 MW wind system have an output variability not exceeding 2 MW/min, up or down, to maintain grid voltage and frequency variations within prescribed ranges. See URL.
The battery systems must be capable of charging and discharging to meet the utility-required ramp rates, while also not overheating the batteries.
Overheating would shorten the battery useful service life, and may cause fires, that burn at high temperatures and take a long time to extinguish.
NOTE: The same holds true regarding overheating of EV batteries, in case of 1) fast charging at a charging station, and 2) fast discharging during accelerating and going uphill, and 3) frequent “range driving”, such as make long trips every day, all of which would increase the likelihood of overheating/damage/fires, especially during hot summer days and cold winter days.
NOTE: This NREL report mentions above issues. NREL is a government, pro-wind entity, which tends to see wind through rosier glasses than private enterprise.

Solar Systems Paired with Grid-Scale Battery Systems
Variable clouds are the main reason for rapid changes of solar output, in addition to the normal daily cycle. See image
Solar output may decrease by 60% within a few seconds, due to a cloud passing over solar systems.
The time taken for the cloud to pass is dependent upon cloud height, sun elevation and wind speed.
These factors need to be considered regarding solar power output forecasting and integrating the variable output into the grid.
The graph shows solar output profiles for ZIP codes in California. The further north, the less solar.
For example, ZIP code 920 shows a downward spike from about 115 MW to 65 MW, or 50 MW in 10 seconds, or 300 MW/minute, at 1 pm, which would significantly affect frequency and voltage stability on the grid.
For at least a decade, California has been mandating utilities to install grid-scale battery systems on their distribution systems.The costs of such battery systems are not charged to solar system owners to perpetuate the fantasy “solar is competitive with fossil”

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT
******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********
(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?
We have the facts on our side. We have the truth on our side. All we need now is YOU.
