Greenville is being eyed for Maine’s latest battery storage project

It is an example of Maine working toward its goal of expanding battery storage capacity despite President Donald Trump’s hard turn against many forms of alternative energy.
Officials in Greenville are considering a proposal to build a battery energy storage facility at a former steam plant.
The project, which was pitched to the town select board last week by the New York-based startup Ground Floor Energy, aims to stabilize the local energy grid. Selectmen allowed Ground Floor to go ahead with a pre-application for a grant from the Northern Border Regional Commission, a government agency that funds rural economic development projects.
The local green light is a first step for a major energy project. It is an example of Maine working toward its goal of expanding battery storage capacity despite President Donald Trump’s hard turn against many forms of alternative energy, including offshore wind technology that has been central to Gov. Janet Mills’ ambitious goals in this policy area.
Much remains unclear about the project, which is still in its earliest stages. There are already seven battery storage facilities that have more than 230 megawatts of capacity, approaching a state goal of 400 megawatts by 2030.
The proposed structure would be housed in Greenville’s former steam plant, which has since been turned into a biochar production facility owned by the local company Clean Maine Carbon. Biochar, a charcoal-like fertilizer made from burning wood material at high temperatures, is considered a green alternative to other fertilizers because it sequesters carbon.

Every wind and solar project in Maine should be paying for every battery installed in Maine as they are the only reason for the need of battery backup. Sudden flucuations in solar and wind outputs along with the sudden drop in solar output upon the approaching sunset stresses the grid that has to rapidly find nearly 1000 megawatts per hour to meet peak hour demand, up from 400 MW per hour. Instead our government will subsidize these batteiries even as the grid operators must pay premium prices to accelerate natural gas and pumped hydro storage and, now batteries to keep up with demand.
Government intervention into grid operations has no foundation of cause as carbon dioxide is no longer a gas that requires reduction. The planet craves more carbon dioxide. The government is designing a crash in plant growth. The government is evil.

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.
