How to Create an Intermittent and Costly
Electricity Supply Industry.
“Large wind farms are being built to take advantage of subsidies, mandated market shares, guaranteed prices and/or government contracts. But because the wind always supplies intermittent energy, everything else on the power grid is forced to also become intermittent. It happens this way:
“When the wind blows, the incremental cost of electricity produced is zero and wind power therefore forces other higher cost generators to temporarily close. They also become intermittent suppliers. This results in costly capital assets earning insufficient revenue to cover debt servicing and standby costs. Investors hesitate to build new facilities, so the supply industry itself risks becoming intermittent because of brownouts or blackouts.
“Once we have intermittent supply it must be matched by “intermittent demand” – some consumers will find their power rationed or shut off by smart meters. Welcome to the cold, dark, green world.”
Viv Forbes - I acknowledge Professor Dieter Helm, Professor of Energy Policy at Oxford University, for his insight on how wind power spreads its intermittency germ throughout the electricity supply industry. Reported in CCNet 17/9/2012.
