Net Efficiency of Maine's Wind Farms

I am interested in knowing the efficiency of Maine's installed wind farm industry.

On an annual basis:

Power generated

(less) Power consumed in operations

___________________________________

Net Power generated

Are these stats published?

Thanks,

This is a little old, but a good document showing the numbers for Maine wind projects. Bingham info is incomplete because 2016 was its first year of operation.

Penny,

Wind turbine owners like to produce as much as possible to spread their costs over many MWh.

Sometimes replacing an entire rotor may provide enough efficiency improvement to make it pay within a reasonable time.

Dartmouth College initially planned to replace its existing central fuel oil heating plant with a tree burning (biomass) heating plant to provide hot water for building heating, but likely will decide to adopt distributed electrical heating systems, such as ground source heat pumps, as have other progressive universities. The electricity would be largely come from remote wind, solar and hydro systems under power purchase agreements, PPAs.

Forestland and Meadowland “Making Room” for Expensive Wind and Solar Electricity

Building access roads to ridgelines (several miles long), and installing wind turbines in various places (on ridge lines at about 3 miles for 60 MW of wind turbines), likely required several thousand acres of forest to be removed.

Near my house, about 6 acres of forest were removed on a slope to install a solar system.

That means no biomass would be grown, and no CO2 would be absorbed at about 1.0 metric ton of CO2/acre/y, due to the clearcutting, etc. See Appendix.

 

- Without cost shifting and without subsidies, the electricity prices to utilities of NE wind and NE solar would be about 18.8 c/kWh and 23.5 c/kWh, respectively.

- With cost shifting and with subsidies, the prices are about 9.0 c/kWh and 11.8 c/kWh, respectively.

- That variable, intermittent electricity could not even exist on the grid without the other generators (mostly gas turbines) performing the peaking, filling-in and balancing, 24/7/365.

Can data be rigged?  If monthly outputs fall short of promised production, what happens then?  What happens when turbines go on the fritz?  The one that burned up at Kibby was listed as an oil leak.  Who really oversees all this?

The NE wind capacity factor is about 0.29, about thé same as Maine.

The US wind CF is about 0.33, largely due to the good winds in Texas and the Great Plains

Penny,

The wind turbine system connected to the grid have to report their monthly outputs, MWh, to the EIA, which is part of the US Department of Energy.

With some googling you may be able to find the spreadsheets.

Where is that information pulled from?  Who tracks and logs it?

Bob, this is a 75day recording across the entire state of Maine that I did last winter through spring. 

The average in Maine never made it to 30% -- This is from 2 samplings per day. I have yet to find a way to automate the entries from my source links.

Hannah Pingree on the Maine expedited wind law

Hannah Pingree - Director of Maine's Office of Innovation and the Future

"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."

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/
