Electricity Supply and Demand this Winter
November 06, 2012
Chubu Electric Power Co.,Inc.
On November 2, the Electric Power Supply and Demand Review Association and the Energy and Environment Council (collectively termed "the national government" below) decided on electric power supply and demand measures for this winter. This announcement concerns Chubu Electric Power's electric power supply and demand outlook this winter as well as energy conservation in the Chubu Electric Power service area based on those measures.
1. Outlook for Electricity Supply and Demand this Winter
Chubu Electric Power reported this winter's supply and demand outlook on October 12 at the request of the Ministry of Economy, Trade and Industry. (This was previously announced on October 12, 2012.) The content of our report was verified by the national government's Supply and Demand Verification Committee before being reported to and confirmed by the Energy and Environment Council on November 2.
[Overview of requested report]
[Peak load (generating end)]
We reported the point peak demand in January 2013 (calculated based on the assumption of severe cold similar to FY2011) as 23,670 MW.
Assuming energy conservation of around 650 MW based on factors including the efforts of our customers the previous summer, we projected an average demand of 22,810 MW for the three days of peak demand. This figure was then corrected for the effects of factors including severe cold.
[Supply capacity (generating end)]
Assuming a supply capacity of 24,800 MW for our service area in January 2013,* we reported a reserve margin of 4.8% in relation to peak demand.
*Including increased output from thermal power stations in case of emergency.
With regard to supply capacity, we project the commencement of commercial operation of Joetsu Thermal Power Station Units 1 and 2 (output: 595 MW) in January 2013; in addition we will provide around 450 MW during the day on weekdays upon request to another electric utility predicting shortfalls in supply.
Our reserve margin in relation to average demand on the three days of peak demand is 8.3%, and we therefore predict that we will be able to maintain stable supply.
2. Provision of power to other companies
Upon request, we will provide a maximum of 450 MW during the day on weekdays to Kyushu Electric Power.
3. Energy conservation in the Chubu Electric Power service area
(1) Details of government request for energy conservation
For this winter, the national government has also reviewed electric power supply and demand measures for the country based on the supply and demand outlooks reported by each of the electric power companies. As a result, the government has requested normal energy conservation measures* without numerical targets throughout the country (with the exception of the service area of Okinawa Electric Power).
*The government has indicated a goal of a reduction of 2.8% against maximum output in winter FY2010 (corresponding to 650 MW) for the Chubu Electric Power service area.
(Period and times for energy conservation as requested by the government)
Weekdays from 09:00-21:00; December 03, 2012 (Mon) – March 29, 2013 (Fri)
*Excepting December 31 and January 02 - 04.
(2) To customers in the Chubu Electric Power service area
With regard to the status of power supply and demand in the Chubu Electric Power service area this winter, we have projected energy conservation of 650 MW assuming that our customers will continue their energy-saving efforts this winter, and we predict that we will have a reserve margin of 8%, the benchmark for stable supply, in relation to average demand for the three days of maximum demand.
We would like to express our sincere gratitude to all of our customers who have assisted us in conserving energy over an extended period since last summer, and we request that you continue efforts of a similar type this winter, to an extent that does not cause any inconvenience.
Chubu Electric Power, for its part, will conduct intensive and focused inspection and maintenance of power stations and transmission and conversion facilities in order to ensure the provision of a stable supply of power to its customers.
