Enviro policies spike CA electricity prices 70 percent

Californians are starting to pay for the cost of the state's Draconian environmental laws.

San Onofre electricity station, wikimediaWholesale electricity market prices spiked about 70 percent over last year.  So reports the Independent System Operator that manages California’s electric transmission and distribution line grids.  The reasons given by the ISO are:

  • Natural gas prices rose about 50 percent over the unusually low gas prices of 2012.
  • Most of the remainder of the increase in electricity market prices was attributed by the ISO to the implementation of the state’s greenhouse gas cap-and-trade program.
  • A decline of about 25 percent in hydroelectric generation also modestly increased electricity prices.

Some experts believe that 2012’s low natural gas prices were due to the increase in supply created from hydraulic fracturing or “fracking.”  But others believe the reason that natural gas prices have risen so high in 2013 is the Obama administration’s mandate to shut down coal-fired power plants and shift to natural-gas-fueled power plants. The electricity price discount from fracking is being wiped out by the shift from coal power to natural-gas-fired power plants.

Cap and trade accounts for nearly all of the other half of the increase in natural gas prices in the second quarter of 2013.

Cap and trade is a policy whereby excess polluters have to pay the California Air Resources Board to buy permits to pollute over a certain emissions cap.  The ISO reports that forward purchases in the wholesale electricity market in the second quarter of 2013 were about $6 per megawatt hour higher due to the implementation of the program.  That reflects about 15 percent of the wholesale price of electricity. The ISO report states the higher natural gas price is “highly consistent with the additional emissions costs for gas units typically setting prices in the ISO market.”

Imported power increasing

Another consequence of the heightened demand for natural gas reported by the ISO is that imports of electricity have not decreased due to the cap-and-trade program.

The ISO report states that both “cleared imports and import bid quantities increased in the first half of 2013 compared to the first half of 2012 by 7 and 13 percent, respectively.”  So California’s plan to wean itself from dependence on imported power is backfiring as a result of cap and trade.

California imports about 25 percent of its electricity from out of state. But these imports are responsible for roughly half of the greenhouse gas emissions from power providers.  CARB suspended its “anti-shuffling” rule in 2012 that required importers to send only low emission power into the state.

Cap and trade wiping out gains from green power

Of possibly greater concern to environmentalists is that the combined effects of mothballing coal power plants outside of California and California’s cap-and-trade program reportedly ate up a $5 per megawatt price decrease from wind and solar power during peak hours during early 2013.

This is because the number of peak hours in the first quarter of 2013 was only 30 to 40 hours due to mild temperatures.  Peak hours are considered from noon to 6 p.m.  High-priced green power can only compete against peak hour prices.  Green power was only competitive for about 1.85 percent of the total hours in the first quarter of 2013.

Back to 2001 in Southern California

Transmission congestion has also raised its ugly head again in Southern California.  Californians learned about grid congestion after the infamous California Electricity Crisis of 2000-01.  Congestion is being mostly experienced in the Southern California Edison service area due to the retirement of the San Onofre Nuclear Generating Station.

The ISO reports congestion is increasing electricity prices in the Edison and San Diego Gas and Electric service territories. Conversely, the ISO reports that this often decreases prices in Northern California in the Pacific Gas and Electric service area.  No explanation was offered in the ISO report for this phenomenon.

Cost of cleaner skies: 70 percent higher electric bill?

The increase in wholesale power prices may not be easily noticeable in electricity bills yet.  An increase of $6 per megawatt hour in the wholesale market is the equivalent to 6 cents per kilowatt-hour at the retail level.  The average price for electricity in California is about 15.2 cents per kilowatt-hour.  Consumers would eventually feel the increase in both higher electricity and natural gas prices.

The average customer, not knowing where the price hike is coming from, may be likely to blame greedy oil and gas companies.  But Californians have been persuaded that they want clean air. The price for that is just starting to show up in customer’s electricity and gas bills.
