California has Excess Power

Excess Power without Nuclear Chart

Excess power without nuclear

San Onofre is permanently shut down and California has excess power without San Onofre and Diablo Canyon nuclear power reactors, according to data from the California Public Utilities Commission (CPUC), the California Energy Commission (CEC) and the electricity grid operator, the California Independent System Operator (ISO).

San Diego Gas and Electric (SDG&E) announced they have adequate resources without San Onofre.

California historically imported significant amounts of electricity, since its wholesale power markets in the region are relatively open and generation from outside the state is often less expensive. Some power plants located in adjacent states are partially owned by California utility companies, and special agreements exist for exporting power to California. For instance, 18% of the Palo Verde Nuclear Power Plant, located in Tonopah, Arizona, is owned by California-based utilities.  See San Onofre nuclear outage contributes to Southern California’s changing generation profile – EIA November 2012.

Generation by Source 2011-12 No SONGS

Source: U.S. Energy Information Administration, EIA Forms 923 and 826.
Note: California’s electricity imports were estimated by subtracting total in-state generation from the EIA Form 826 from total in-state generation from the EIA Form 923. Renewable energy in the chart includes: wind, photovoltaic, geothermal, and biomass.

 

This 12-year California Power Mix Trend Chart shows a slow progression to renewable energy. The California Energy Commission (CEC) doesn’t count distributed solar (e.g., rooftop solar) and other power sources under 1MG. However, this chart shows major improvements are still needed in the area of renewable energy. Part of this web page includes information on problems with the implementation of renewable energy in California and recommended solutions.

California Power Mix Trend (12 years)

The ISO’s plan kept us in power for all of 2013 without San Onofre. This included electricity needed for peak load periods in the summer as well as voltage and grid stability. They stated “…the reliability risks to southern Orange and San Diego counties are “marginally more challenging” this summer, but still within planning standards.” See ISO 5/6/2013 News Release.

Bill Powers’ 9/21/2012 Quail Brush presentation shows SDG&E has a surplus of energy without San Onofre and does not need to build new gas plants to meet local needs. (Data based on ISO 2012 Summer Loads and Resources Assessment 3/15/2012).

      • State “reserve margin” requirement is 15% to 17%. Reserve margin means additional power supply available beyond what is needed to meet the typical weather year peak load.
      • Forecast 2012 peak reserve margin for Southern California (SoCal Edison + SDG&E) with San Onofre is 29%This is over 8,000 MW above projected peak load of 27,399 MW.
      • Forecast 2012 peak reserve margin for SoCal without San Onofre is 23%This is over 6,000 MW above projected peak load of 27,399 MW.

Federal Energy Regulatory Commission (FERC) Chairman Jon Wellinghoff says we’ll be in fine shape without San Onofre this summer

“…and there certainly may be the opportunity to retire certain types of resources like nuclear facilities if the state were to chose to do so,” the FERC chairman said. UT San Diego 06-04-2012

The FERC Summer 2012 Energy Market and Reliability Assessment supports this: 

Without the 2.3 GW from this [San Onofre] plant, NERC forecasts that projected reserve margins in California may be close to, but still be above, the regional target of 15.1 percent.

See NERC’s 2012 Summer Reliability Assessment (page 8 and 9).

The North American Electric Reliability Corporation’s (NERC) mission is to ensure the reliability of the North American bulk power system.

Southern California Edison says they have ample power without San Onofre – OC Register 02-02-2011

San Onofre’s two reactors have been shut down since January 31, 2011 due to critical equipment problems. There have been no resulting blackouts or brownouts in Southern California.  The electricity grid was able to compensate for this loss.

Rolling blackouts have not occurred with San Onofre offline

Nuclear Plant Owners Refuse to Provide Plans for Shutdown

      • California nuclear plant owners have not provided plans for alternate sources of energy to replace nuclear power.
      • Plans are needed in case of emergency shutdown and to prepare for license expiration of the plants.  Their plan is to continue relicensing these old plants.  The plants were originally designed for a lifespan of 40 years or less. San Onofre licenses expire in 2020.  Diablo Canyon licenses expire in 2024 and 2025.
      • The plant owners have refused to comply with state requests to provide their plan for an alternative energy source prior to relicensing.
      • Nuclear power is not a reliable source of power, as shown by the months of unplanned shutdown of San Onofre since January 2012.

Percent of power from San Onofre

There are numerous percentages quoted regarding how much electricity San Onofre provides.  However, the real question is not how much it provides, but how much it needs to provide.  However, for those interested in the percentages, here they are:

San Onofre is operated by Southern California Edison, which owns 78.21%. SDG&E owns 20% and Riverside Public Utilities owns 1.79%.

Diablo Canyon (located in San Luis Obispo), is owned and operated by Pacific Gas & Electric (PG&E)

    • Reactor Unit 1 provides up to 1073MW, in service since 1985.
    • Reactor Unit 2 provides up to 1087MW, in service since 1986.

Cost of Nuclear Power

Reports of nuclear power costing less than other sources of energy needs to be reevaluated in California, especially at San Onofre.  For example, the cost analysis to replace the San Onofre steam generators assumed high gas prices.  It also excluded the cost of storing tons of toxic radioactive waste for tens of thousands of years as well as numerous other costs. It excluded all energy efficiency alternatives, such as targeted and increased cost incentives to replace residential and commercial  inefficient air conditioners and load balancing in the Edison and SGD&E utility districts.

Energy Efficiency

The average household can cut their electricity bill by 50% through energy efficiency.

Household Energy Comsumption

    • See energy saving tips.
    • See available rebates.
    • Heating and cooling are almost half of energy consumption, yet rebates are limited or non-existent for heating and air conditioning systems (HVAC).
    • SCE and SDG&E are given billions of dollars of ratepayer money for energy efficiency programs. SCE currently has about half a billion dollars in energy efficiency funds that must be used by the end of 2012.
    • California’s concerns about peak energy demand in the summer and carbon emissions can more effectively be addressed with more aggressive incentives and programs for central air conditioner replacements — especially in the area served by the San Onofre nuclear power plant.
    • SCE and SDG&E offer residential customers no rebates to upgrade to more efficient central heating and cooling (HVAC) systems. They only offers rebates on installation costs for new air conditioning systems. The number of contractors to choose from is limited and there are other hurdles that make this program less attractive. The information is difficult to find on SDG&E’s website. They send you to a vendor website for information, without mentioning the amounts of rebates possible for installation.
    • SDG&E’s Energy Efficiency Business Rebates Product Catalog lists rebates available to business.  No central air conditioning systems are included.
    • SCE’s Business Solutions Directory contains the most complete and current list of eligible equipment (solutions) and qualification criteria for incentives available to customers through SCE’s 2010–2012 Energy Efficiency Program. It also includes a summary of Demand Response Technology Incentives available for customers installing qualified equipment that enables load-shifting strategies. For updates on program changes (due to funding availability or other other reasons), go to SCE Energy Management Online Application Tool. SCE has recently added  ice storage air conditioning installation rebates to their HVAC Optimization Program.

Southern California Edison stalls solar projects for years

Millions of dollars in renewable energy projects intended to provide power to facilities in California’s national parks and forests have been sitting idle for years because of Southern California Edison.

There’s 24-plus systems in the Southern California Edison area that have been installed in the last three years that we have not been able to negotiate an interconnection agreement on,” said Jack Williams, who retired this month as the National Park Service’s Oakland-based regional facilities manager. “We think we are close at times, but then nothing. We were successful with PG&E, but with Southern California Edison…. They have been a bit more difficult. We’ve raised the flag many times. It’s an issue for all federal agencies.”

Nuclear Power is no solution to Climate Change

See NIRS slide presentation explaining why nuclear power is no solution to climate change.

A Plan to Power 100 Percent of the Planet with Renewables

A 2009 Stanford University study ranked energy systems according to their impacts on global warming, pollution, water supply, land use, wildlife and other concerns. The very best options were wind, solar, geothermal, tidal and hydroelectric power—all of which are driven by wind, water or sunlight (referred to as WWS).

Nuclear power, coal with carbon capture, and ethanol were all poorer options, as were oil and natural gas. The study also found that battery-electric vehicles and hydrogen fuel-cell vehicles recharged by WWS options would largely eliminate pollution from the transportation sector.

To ensure that our system remains clean, they considered only technologies that have near-zero emissions of greenhouse gases and air pollutants over their entire life cycle, including construction, operation and decommissioning. For example, when burned in vehicles, even the most ecologically acceptable sources of ethanol create air pollution that will cause the same mortality level as when gasoline is burned. Nuclear power results in up to 25 times more carbon emissions than wind energy, when reactor construction and uranium refining and transport are considered.

Nuclear Power in France: Setting the Record Straight

France gets nearly 80% of its electricity from its 58 nuclear reactors. However, such a heavy reliance on nuclear power brings with it many major, unresolved problems most especially that of radioactive waste. As a result, France has a hugely complex and unsolved radioactive waste problems, as well as health, environmental, and financial problems.

Like the United States:

        • France has not solved its nuclear waste problem.
        • French nuclear power has been costly to taxpayers.
        • French reactor technology is aging and unsafe.
        • French reactors, and reactor construction projects, are unreliable.
        • The French do not all love their nuclear power.
        • France’s nuclear power has produced serious health and environmental problems.

Thorium Fuel: No Panacea for Nuclear Power

Thorium “fuel” has been proposed as an alternative to uranium fuel in nuclear reactors. There are not “thorium reactors,” but rather proposals to use thorium as a “fuel” in different types of reactors, including existing light-water reactors and various fast breeder reactor designs.  Contrary to the claims made or implied by thorium proponents, however, thorium doesn’t solve the proliferation, waste, safety, or cost problems of nuclear power, and it still faces major technical hurdles for commercialization.  See Fact Sheet by the Institute for Energy and Environmental Research and Physicians for Social Responsibility.

AP1000 Nuclear Reactor

 

The new AP1000 nuclear reactor has serious design flaws. On a 4 to 1 vote, the NRC Commissioners approved building this in Georgia, even though numerous problems exist with the design and lessons learned from Fukushima have not been implemented.  Vogtle nuclear plant now under construction in eastern Georgia.

    • For example, see Containment Leakage,  An Unreviewed Safety Issue, April 7, 2010, Arnie Gundersen, Fairewinds Associates.
    • The AP1000, as well as other new reactor designs, use high burnup fuel. High burnup fuel waste is so dangerous, the NRC will not approve a transportation container for it and will only approve 20 years of dry storage for it. More…
    • George ratepayers are required to pay for the construction of this plant before it’s even built, with no guarantees it will be successful.
