As Power Use Peaked, GMP Ordered To Cut Lowell Wind Output
Last week, when electricity demand hit a near all time high in New England, the operator of the regional electric grid ordered the Lowell, Vt. wind project to cut its power output.
The move baffles the utility and wind developers. They question why a renewable energy project was scaled back when polluting power plants everywhere in the region were told to run full blast.

But it issued a contrary order to Green Mountain Power. The utility was told to cut power output from its 21 turbine wind project in Lowell. GMP spokeswoman Dorothy Schnure said utility executives were perplexed by the order since ISO also wanted GMP to put its rarely used fossil-fuel generators on line.
Last week, the ISO actually was telling people to use less power at the same time that it was telling us to turn on our diesel fuel units and limiting what we could generate at our wind plant, she said.
Schnure said the utility was asked to curtail output from the Lowell project by 15 to 30 megawatts. Lowell has a maximum capacity of 63 megawatts. She said GMP asked ISO New England for a reason for the cut-back order, but has not been given one.

(6,905 posts)without being specific about why. The operator of Lowell is going to install a synchronous condenser near the Lowell plant. Apparently this would be used to correct the line power factor and increase it's capacity. The correction would only be on the line between the generators and the condenser.

(6,905 posts)I just can't imagine not using available wind power.

(114,904 posts)But David Blittersdorf, a wind energy developer, said last weeks cutbacks on Lowell dont make sense since the demand for electricity was high both region-wide and in the Northeast Kingdom.
The idea behind the curtailment on Lowell is that they have this system problem and a weak grid. But if your loads right there, that doesnt matter, he said. You want to supply it with the generation thats right there. Its not going hundreds of miles away, which a weak grid would have a problem with. So I consider what theyre doing really bizarre.

(48,121 posts)If they are reaching max output other sources are not as easy to shut down and restart (turbines also have less staff generally that would be idled in such a case).
We had a lot of controls in place to monitor usage and shut down windmills automatically given certain conditions (and based on a maintenance schedule which tied into rotations/etc).
In hydro/coal vs wind it takes a lot less work to shut down a few turbines.
Just my experience.

(19,429 posts)you do not want sources which vary with wind speed which would cause other generators to have to throttle up and down to compensate for wind variability.
