Could this happen in Colorado? Maybe…
A Wall Street Journal article reports what some in Colorado’s energy industry know, too much reliance on wind and solar can make an electric grid unstable and lead to power outages.
California regulators and energy companies met last week out of fear that the state’s electric grid is so unstable due to heavy dependence on wind and solar that rolling blackouts will begin as early as 2015. The WSJ reports:
Regulators and energy companies met Tuesday, hoping to hash out a solution to the peculiar stresses placed on the state’s network by sharp increases in wind and solar energy. Power production from renewable sources fluctuates wildly, depending on wind speeds and weather.
California has encouraged growth in solar and wind power to help reduce greenhouse-gas emissions. At the same time, the state is running low on conventional plants, such as those fueled by natural gas, that can adjust their output to keep the electric system stable. The amount of electricity being put on the grid must precisely match the amount being consumed or voltages sag, which could result in rolling blackouts.
At Tuesday’s meeting, experts cautioned that the state could begin seeing problems with reliability as soon as 2015.
California, which has a 33 percent renewable mandate, has plenty of power but…
Even though California has a lot of plants, it doesn’t have the right mix: Many of the solar and wind sources added in recent years have actually made the system more fragile, because they provide power intermittently.
This story should serve as a warning to all, such as Rep. Max Tyler (D-Lakewood) and former Governor Bill Ritter, who think that government mandating electricity generated from wind and solar is as simple as passing legislation while ignoring science and technology.
In a March 2010 press release Tyler bragged about his bill increasing Colorado’s renewable mandate to 30 percent:
The sun will always shine for free, the winds will always blow for free, and our energy production will be cleaner. Renewable energy, green jobs, and a cleaner future — what’s not to like?
What’s not to like? How about an unstable grid that leads to blackouts. Get your generators now.
