  6. 6. ○ Change in power supply sources of (general and wholesale) power generation companies after the Earthquake ○ Fuel cost increase by termination of nuclear power plants * For FY2013, the influence to cost is calculated by correcting the exchange rate used for the estimation in FY2012 to the current value of 100 yen/dollar and assuming that the operation status of the nuclear power plants would not change in FY2013 from FY2012. ○ No operating nuclear power plants →About 30% loss of power supply, Tight balance between demand and supply ○ Due to stop of nuclear power plants, the fuel cost for thermal power generation is expected to increase by about 3.8 trillion yen in FY2013, which is about 20% of electricity prices ○ The cost would increase more if the oil price increases by a tense situation in Hormuz Composition of Power Generation after the Quake Disaster Power source Fuel cost (FY2012) Influence to cost Estimation in FY2012 Estimation in FY2013 (*) Nuclear power 1 yen/kWh - 0.3 trillion yen - 0.3 trillion yen Coal 4 yen/kWh + 0.1 trillion yen + 0.1 trillion yen LNG 11 yen/kWh + 1.4 trillion yen + 1.6 trillion yen Oil 16 yen/kWh + 1.9 trillion yen + 2.4 trillion yen Total - + 3.1 trillion yen + 3.8 trillion yen 20% 25% 26% 25% 20% 27% 26% 26% 24% 23% 38% 41% 42% 47% 50% 46% 48% 48% 49% 32% 5% 7% 13% 17% 16% 13% 16% 18% 13% 5% 28% 16% 10% 5% 1% 1% 3% 2% 3% 32% 9% 11% 8% 5% 12% 12% 7% 6% 11% 8% 63% 73% 81% 90% 87% 87% 90% 92% 86% 28% 16% 10% 5% 1% 1% 3% 2% 3% Apr 2011 Jul Oct Jan 2012 Apr Jul Oct Jan 2013 Apr FY2010 Coal thermal power generation LNG thermal power generation Oil thermal power generation Nuclear power generation hydro-electric power generation Thermal power generation Nuclear power generation 5
  7. 7. Change in Fuel Price ○ In comparison to crude oil and LNG, the change of the coal price has been stable at a low level. ○ As of April 2013, the crude oil price (7.36yen/1000kcal) is about 4.1 times higher and the LNG price (6.32/1000kcal) is about 3.5 times higher than the coal price (1.81 yen/1000kcal).

  15. 15. (1) Large Combustion Plant Directive (LCPD) ・ Target: Combustion plants (coal-fired power plants, etc.) with generating capacity of 50,000 kilowatts or more ・ Details: It sets emissions restrictions on both existing and new facilities with the aim of reducing air pollutant emissions (SO2, NOx, PM) in the EU. Although the power plants that were constructed before 1987 and did not meet the standard were to be decommissioned in 2007, by developing a plan for the decommissioning after 2016, each country can operate these plants within an operating time of 20,000 hours from 2008 to the end of 2015. Current regulations on Coal-fired Power Generations in Europe (1) Energy and Climate Change Package ・Target: EU ・Goal:・To reduce greenhouse gas (GHG) to 20% below 1990 levels by 2020. ・To boost the share of renewable energy in final consumption to 20% by 2020. ・To improve energy efficiency by 20% by 2020. (2) Restriction on emissions by new coal-fired power plants in the UK ・Target: UK ・Details: When a coal-fired power plant is established, it needs to have a standard for CO2 emissions of 450g-CO2/kWh and to apply CCS. Regulation concerning Air Pollution Prevention Regulation of Greenhouse Gas Emissions News Reports about Coal-fired Power Generations in Europe  Increased coal-fired power generation and an sluggish gas-fired power generation are accounted for by soaring natural gas prices and falling prices for CO2 emissions credits. <Snip> As a result, German policy of breaking with nuclear power generation promotes coal-fired power generation. On August 15, RWE has formally started operating a brown coal-fired power plant with power generation efficiency of 43% that introduced the latest technology near Korn in the midwest of Germany. Environment Minister Peter Altmaier praised this for "making significant contributions to successful energy conversion in addition to promoting CO2 emissions reductions". (Source: Bloomberg, August 21, 2012)  In the EU, the percentage of coal-fired power generation in electricity generation rose by as much as 7% year-on-year in 2012. The growth rate hit the highest level in the past 40 years. According to a chief economist at the International Energy Agency (IEA), "Coal has been plentiful in the US, where shale gas was found, and cheap coal that has no where to go has flowed into Europe. Far cheaper gas prices in North America than appropriate prices has boosted coal consumption." (Source: Nikkei Business, March 5, 2013)  On May 6, 2013, Germany Kreditanstalt fur Wiederaufbau announced that it would continue financial assistance to projects of coal-fired power plants. It will financially support the replacement of coal-fired power plants and the construction of highly-efficient thermal power plants, and promote the introduction and spread of sophisticated power-generating technologies.

  27. 27. Chapter 2. Section2. Position of each energy source and policy time frame (1) Renewable energy  Renewable energy has various challenges in terms of stable supply and cost at this moment, but it is a promising, multi-characteristic and important energy source which can contribute to energy security as it can be domestically produced free of greenhouse gas emissions. (2) Nuclear power  Nuclear power’s energy output per amount of fuel is overwhelmingly large and it can continue producing power for several years only with domestic fuel stockpile. Nuclear power is an important base-load power source as a low carbon and quasi-domestic energy source, contributing to stability of energy supply-demand structure, on the major premise of ensuring of its safety, because of the perspectives; 1) superiority in stability of energy supply and efficiency, 2) low and stable operational cost and 3) free from GHG emissions during operation. Description of "Strategic Energy Plan" (Excerpt) 26
  28. 28. (3) Coal  It is now being re-evaluated as an important base-load power supply. It is an energy source that we should use while reducing the environmental load through the utilization of highly efficient coal thermal power generation technology, etc. (4) Natural Gas  Natural gas plays the central role as an intermediate power source. Natural gas is an important energy source whose role is expected to expand. (5) Oil  It’s advantage lies in its wide applicability as fuel in the transportation, consumer, power supply sectors and also as materials for chemical and other products. Especially, the transportation sector relies heavily on oil. It will continue to be used as an important energy source. 27 Description of "Strategic Energy Plan" (Excerpt)

  31. 31. Position Though coal has a problem ― it emits a large amount of greenhouse gas ― it is now being re-evaluated as an important base-load power supply because it involves the lowest geopolitical risk and has the lowest price per unit of heat energy among fossil fuels. It is an energy source that we should use while reducing the environmental load through the utilization of highly efficient coal thermal power generation technology, etc. Policy Direction 30 Position of the coal in "Strategic Energy Plan" In addition to promoting the replacement of aging thermal power plants and introducing available leading-edge technology through the construction of new facilities and the expansion of existing ones, GOJ further promotes the development of technologies to drastically reduce greenhouse gas emissions per unit of generated power (e.g., IGCC) by largely improving the power generation efficiency. It is necessary to use coal while reducing the global environmental load by promoting the introduction of such high-efficiency technologies not only in Japan but also globally.
