The hidden costs of wind power in Alaska (and everywhere else!)

Here is a simple explanation why BigWind is BAD for our electrical grid AND why it is NOT GREEN.  Alaska does differ from our other united states, however, because they do use oil to generate power. Here, in Ohio, we predominantly use coal and natural gas as our backups for BigWind.  It is also noteworthy, the titles of this author, he’s no dummy…see last line.  Senator Cliff Hite, of Ohio, however, wants MORE BigWind on Ohio’s grid.  He is proposing shorter safety setbacks, so more industrial wind turbines can be placed on our rural lands.  Remember, not only will BigWind harm our grid, but it will raise our electrical prices and BigWind evades taxes by insisting on county PILOTS (payments in lieu of taxes).  It’s time for Senator Hite to take a hike!…..

Most people assume wind power is the cheapest, greenest power Golden Valley Electric Association generates. But if wind power is not carefully balanced with other power sources, it can drive up your electric bill — as well as greenhouse gas emissions.

GVEA’s board has been very cautious about adding more wind. Here’s an anecdote that explains why more wind could lead to higher emissions and higher bills.

 Let’s suppose it’s a nice, windy day north of Healy, and the Eva Creek Wind Farm is producing power. Then the wind dies off. Suddenly, 25 megawatts of generation disappears. To prevent a power outage, GVEA must have an oil-fired power plant available to pick up the generation that was lost. As the wind fluctuates, the plant must be regulated — revved up or down — in sync with the wind.

Therefore, every megawatt of wind power the Eva Creek Wind Farm generates requires an oil-fired power plant to be running in the background. Our oil-fired units are the only ones that can react fast enough to match the changing output of the wind turbines. Coal-fired plants and purchased natural-gas power are not able to assist in regulating wind-generated power. Our coal-fired power plants are the least expensive source of power and are operated at full load; this is called a base load plant. Gas-fired generation from Anchorage is scheduled a day in advance, thus not making it available for regulation.

Oil is more expensive than coal and natural gas. But burning oil is one of the least-considered costs (both from economic and environmental standpoints) associated with operating the Eva Creek Wind Farm.

In December, GVEA received a request for interconnection from Delta Wind Farm Inc. for a proposed 13.5-megawatt wind generating facility. After GVEA carefully considered the benefits and costs associated with the project, we filed a Notice of Denial of Interconnection with the Regulatory Commission of Alaska.

An independent, third-party analysis showed that Delta Wind Farm would increase fuel costs for our members, as well as plant maintenance costs. It also had the potential to increase emissions of greenhouse gases. While our power plants have scrubbers and produce less than 5 percent of the emissions that contribute to the PM 2.5 issues in North Pole, any increase of pollutants in sensitive areas needs careful consideration. GVEA’s own Eva Creek Wind Farm (25 MW) is specifically sized for GVEA’s system. There are times, especially in the summer months, when we can’t even use all the available power from Eva Creek because our oil-fired plants are operating at their lowest levels….
