“Coal-fired power plants are closing, unable to meet EPA environmental guidelines. Nuclear plants are aging and beset by mounting losses, driven by negative pricing from subsidized wind systems. Without a return to sensible energy policies, prepare for higher prices and electrical grid failures.”

Americans take electricity for granted. Electricity powers our lights, our computers, our offices, and our industries. But misguided environmental policies are eroding the reliability of our power system.

A Close Call This Winter

Last winter, bitterly cold weather placed massive stress on the U.S. electrical system and the system almost broke. On January 7 in the midst of the polar vortex, PJM Interconnection, the Regional Transmission Organization serving the heart of America from New Jersey to Illinois, experienced a new all-time peak winter load of almost 142,000 megawatts.…

“It is well known that Texas is undergoing a major challenge in maintaining resource adequacy due to improper price signals; less well known is that a significant portion of the problem can be laid directly on the doorstep of subsidies for wind generation.”

The federal Production Tax Credit (PTC), which currently provides a $0.022/kWh subsidy to qualifying renewables, is set to expire at year-end. Just the prospect of expiration has dramatically slowed new construction of industrial wind capacity, despite a raft of other subsidies to politically correct energy. [1]

The Texas Public Policy Foundation has released a new paper looking at the effect of the production tax credit both on taxpayers and consumers. Bill Peacock and I found that PTC continuance puts the Texas electricity market at increased risk of price spikes and blackout by discouraging the construction of new reliable, on-peak generating capacity.…

On Wednesday morning, The Electric Reliability Council of Texas (ERCOT), operating the power grid for much of the state, called upon local distribution companies to cut power to blocks of consumers on a rotating basis.

The rolling outages produced hardship for millions, and even isolated instances of severe harm. Consumers and policymakers are dissecting what went wrong and what should be done about it. The following is a preliminary analysis based on public data and news reports. A subsequent post will present more details once more complete information becomes available.

In brief, extreme cold weather pushed power demand to very high winter levels.…

Losing electricity is no fun, whether it is momentary (sensitive equipment can get fried) or for days or weeks, as many of us Houstonians experienced in the wake of Hurricane Ike.

News accounts from Hawaii report that the vacationing President-elect Barack Obama was without power from the early evening until morning due to storms. The Washington Post reported: …
