Japanese utilities wary over hedging in power futures

Japan's main power utilities remain cautious about using power futures contracts to hedge against the risk of decline in the country's wholesale electricity prices, even after the country experienced unexpectedly significant volatility in wholesale prices in January.

Only Tohoku Electric Power sells futures contracts through its group firm, while other nine utilities have never used the hedging tools, the recent survey by the Japan Electricity and Gas Market Surveillance Commission (EGC) under the trade and industry ministry (Meti) showed

The other utilities include Hokkaido Electric Power, Tokyo Electric Power Energy Partner (Tepco EP), Chubu Electric Power Miraiz, Jera, Hokuriku Electric Power, Kansai Electric Power, Chugoku Electric Power, Shikoku Electric Power and Kyushu Electric Power. Japanese auditors have not accepted hedge accounting for power futures contracts, said the utilities as a reason they do not use the hedging system. A lack of experts familiar with futures trades is another reason, they added.

The survey also found that six utilities, including Tohoku, Tepco EP, Miraizu, Jera, Kansai and Kyushu, offered electric power supplies on the country's forward market over January-May. But three firms only focused on selling a few weeks forward and did not cover the winter peak demand season.

Utilities that have not sold on the forward market preferred to sell through brokers and bilateral trading because of the flexibility in transaction terms.

The finding was part of the EGC's survey conducted in June, which aimed to ensure fair trades by main utilities against their retail power arms and other retailers.

The EGC in April conducted surveys with 253 power producers and retailers to analyse the extent of pervasiveness of the hedging mechanism in the country's power industry. The result showed that only 4pc of 26 power producers use the Tokyo Commodity Exchange's platform, while none use the German-based European Energy Exchange. But around 30pc of the power producers planned to participate in futures trading at both exchanges.

The lack of a selling hedge may cap further growth in liquidity of the futures and forward markets, while Meti has called for the effective use of such trading systems to offset the impact of large price fluctuation following a spike in wholesale power prices earlier this year. The sharp rise was caused by a series of factors, including extended icy weather, higher than expected demand, lower nuclear and solar output and a shortage of thermal generation fuels, especially LNG.
