Nuclear Reactors 191 – Japan Changes Rules For Grid Access for Renewable Energy
Following the Fukushima nuclear disaster in Japan in March of 2011, Japan shut down all of it nuclear power plants. Abe, the new Prime Minister of Japan has targeted the domestic nuclear industry as being critical to the economic expansion of Japan, both internally and as a source exportable technology. Despite widespread public opposition, Abe has pushed forward to restart Japan’s idle nuclear power reactors. Draconian laws have been passed to prevent the media from departing from the official government line on the need for and safety of nuclear power in Japan.
In mid 2012, a feed-in tariff system was enacted which requires Japan’s ten utilities to purchase electricity made from solar, wind, geothermal, mini-hydro and biomass sources from private firms. Many companies rushed to take advantage of the guaranteed fixed price per kilowatt hour provided by the feed-in tariff. There were many more applications under the program than anticipated by the central government. The national government has approved almost a million and a half projects under the new system. Around half of these projects focus on small rooftop solar projects that produce less than ten kilowatts of electricity. Over a thousand projects have been approved that produce more than two megawatts of power.
Last September, Kyushu Electric Power Company (KEPC) announced that they would “no longer sign contracts with most companies that were supplying renewable energy.” The reason given was that the KEPC transmission network could not handle the estimated load if KEPC actually purchased electricity from all the renewable energy providers that it had contractual arrangements with. Four more of the ten utilities in Japan quickly announced the same policy that KEPC adopted. This action by the utilities caused many supporters of renewable energy to complain that this would reduce Japan’s move to renewable energy sources.
Recently, in response to the feed-in tariff situation, an agency of the Ministry of Economy, Trade and Industry issued a revision of the feed-in tariff system rules for the national electrical grid. Supporters of the revisions say that government intervention will ” ensure safe and stable supply of all forms of electricity by helping to prevent renewable energy from overloading the grid and causing blackouts.” Critics of the new rules say that the real reason for the revisions is to limit the production of renewable energy so that when the nuclear power plants are brought back online, there will sufficient grid capacity to accept the power that they generate.
Under the original feed-in tariff system, companies could sign contracts to supply electricity to the utility grids but they did not have a deadline set for construction. Obviously, some firms opted to delay construction in hopes that the cost of construction would fall and they would make a greater profit. The new rules call for the setting of deadlines for construction. If a company misses the deadline, it might lose the right to access the utility transmission network. Originally, the feed-in tariff system limited output of renewable energy sources to a maximum of thirty days a year. The new rules call for limits that are calculated by the hour. This will provide flexibility and insure that there is sufficient grid capacity to accept available energy.
The government has said that it wants to reduce Japan’s reliance on nuclear power but the new feed-in tariff rules are based on the assumption that Japan’s idle nuclear power plants will be brought back on-line and need grid capacity that could be supplied by renewables.

Wishing Everyone a Happy New Year!
I don’t have any predictions or resolutions. I do hope that in the year ahead, there is not a major nuclear accident or the detonation of a nuclear bomb anywhere in the world. I also hope that the public and investors continue to abandon nuclear power in favor of efficiency, conservation and renewables.

Nuclear Reactors 190 – Entergy Closes the Vermont Yankee Nuclear Power Plant
The supporters of nuclear power are trying to crank up public support and investors for a variety of nuclear power projects. Unfortunately for them, energy efficiency and conservation are estimated to cost one fourth of the price of a new nuclear power plant. Wind power and cheap natural gas are estimated to be about half the cost of nuclear power. Reactors that are currently under construction in the U.S. and Europe are over budget and behind schedule. While the cost of building a nuclear reactors are well understood, there is less appreciation for escalating operating costs. As reactors age, they become more and more expensive to repair. At some point, it is no longer economically feasible to keep repairing an old reactor. Nuclear power has strong political support and is fighting to prevent renewable energy sources from being exploited but, hopefully, it is losing the battle.
Entergy is closing the Vermont Yankee power plant in Vernon, Vermont. The company is being forced to close the plant because it is no longer profitable. Electricity demand is down, cheap natural gas is abundant and nuclear power is not being given the special “consideration” (tax breaks, loan guarantees, guaranteed electricity prices, etc.) its supporters think it is entitled to. Critics of the closing predicted that the bills of New England ratepayers would increase by forty percent this winter because the power plant is being closed.
Last year, N.E. energy prices were about thirty six percent above the average electricity cost in the U.S. In 2004, N.E. electricity cost thirty six percent above the average electricity cost in the U.S. Now it is estimated that N.E. electricity costs will rise by about three percent in the next year as compared to a rise of about two and a half percent for U.S. in general. It does not seem as if having the Vermont Yankee power plant operating did much to lower the cost of electricity in N.E. Supporters of the closing say that removing Vermont Yankee from the grid in N.E. will not have much impact on the cost of electricity for the region.
The Maine Public Utility Commission recently conducted a study of the N.E. power supply system. The Commission presented what it considered to be the optimal mix of energy sources for N.E. Their projection included consideration of price risks and carbon emissions. They did not include nuclear power in the mix. Natural gas was only about one sixth of the mixture of desirable energy sources. Many financial analysts with big institutions have projected that improving energy efficiency, stepping up conservation and implementing renewable energy sources should be able to supply electricity demand for the next several decades. One of the problems that they highlight is the fact that huge centralized power generation is too big and too inflexible to meet the energy needs of the future.
Many studies have shown that nuclear power cannot compete with available alternatives in terms of either construction costs or operating costs. A great deal of work is being done to develop practical battery systems to back up intermittent power sources like wind and solar. When these new battery systems go into operation in the near future, one more excuse for continuing to use nuclear power will be gone. Let us hope that policy makers pay attention and refuse to be seduced by empty promises of the nuclear industry.
