Weekly Summary

Power: Mar 16-20: Power plant stoppages underpin prices

Wholesale electricity prices in Japan markets clawed back ground a touch in the short week ending March 20 owing to the national holiday of Mar 20, propped up by lower supply created by power center shutdowns, despite the weaker demand amid the non-seasonal warmth and sunny skies. Based on the Rim Power Index (Day ahead 24 hours), the weekday power prices in the eastern market, including the Hokkaido, Tohoku and Tokyo area, averaged out at 8.18 yen per kilowatt hour (kWh), up 0.78 yen/kWh or 10.5 % from the previous week, meanwhile prices in the western, made up of the Chubu, Hokuriku, Kansai, Chugoku, Shikoku and Kyushu area, at 5.69 yen/kWh, up 0.47 yen/kWh, or 9.0%.

 

A slew of thermal power plants went off for maintenance works both in east and west Japan, shedding supply capacity significantly.

The price disparity between Hokkaido and Tokyo grew to 2.49 yen/kWh from the prior week's 2.03 yen/kWh, with Hokkaido's average 10.50 yen/kWh (previous week's ave:9.33 yen) and Tokyo's 8.01 yen/kWh (7.30 yen), which are reckoned in conformity to data compiled by the Japan Electric Power Exchange (JEPX). Hokkaido prices often move at higher levels than other areas especially in the winter season. In the week, prices in Tohoku, where prices usually show a marked tendency to keep the same moves at the same levels as Tokyo, fell below the eastern neighbor in the week, with its average of 7.79 yen/kWh (6.91 yen/kWh).

Kansai's weekly average gained by 0.95 yen/kWh to 6.30 yen/kWh, and Kyushu's added 0.80 yen/kWh to 5.44 yen/kWh. The differential of two areas stood at 0.86 yen/kWh, compared with 0.71 yen/kWh observed in the prior week. Kansai area is the largest market in the western Japan, and Kyushu's prices are inclined to hover at less expensive levels alongside of other areas.

 

On JEPX, the weekday average of System Price (Day ahead 24 hours), which were figured based on the data of 9 areas, moved up by 0.55 yen/kWh to 6.66 yen/kWh from the previous week's 611 yen/kWh, with the average volume standing at 835,960 megawatt hour (MWh) compared to 844,929 MWh seen in the prior week.
