Real Clear Energy: Wind Will Be Difficult to Integrate into the Grid

Wind Will Be Difficult to Integrate into the Grid

By Editors

The electrical grid is a high-wire act in which supply must be matched with demand on a minute-to-minute basis. If supply surges above demand, electrical equipment everywhere can be damaged. (That’s why you have a “surge protector” between your computer and the wall outlet.) If supply slumps below demand, brownouts and blackouts can occur.

Although windmills have great energy potential, they produce electricity that is not “dispatchable.” In other words, it cannot be called at will by the operator but comes and goes as the wind blows. As wind energy becomes a larger and larger part of the electrical grid, the problem of matching supply and demand will become ever more difficult.

To illustrate the problem, the PJM (Pennsylvania, New Jersey, Maryland) regional grid has produced a line graph matching showing how actual demand compares with the projected output of a grid powered 100 percent by windmills.

The horizontal axis represents the two factors over a period from December 18, 2008 to January 22, 2010. The red line represents grid demand, which varies between 50,000 and 100,000 megawatts (MW) on a seasonal basis. The blue line represents wind’s output over the same period. Output varies wildly, from highs of more than 300,000 MW to lows of nearly zero. It is important to remember that these are not necessarily seasonal or even daily variations. The output of a windmill can fall from full capacity to zero in a matter of hours.

In all those periods where output falls below demand, wind will have to be supplemented by other forms of generation, most likely natural gas. In periods where its output exceeds the demand, the surplus electricity will have to be dumped unless technologies for utility-sized electrical storage can be developed. Currently, the only technology is pumped hydroelectric storage, which requires a large reservoir in a mountainous area, a rare combination.

Unless new storage technologies can be developed, the addition of wind capacity to the electrical grid will not be able to do much in reducing the use of other fuels. The important thing is not gross output but the matching of supply and demand.

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/

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.
