摘要

1. Day-ahead spot electricity prices on the Japan Electric Power Exchange tend to be linked to fuel costs for oil-fired power generation positioned as marginal supply capacity. In line with oil price hikes in 2018, the average day-ahead spot electricity price remained around 10 yen/kWh. As oil-fired power generation has shrunk, however, regions and time slots where spot electricity prices depend on variable costs for gas-fired and coal-fired power generation have been emerging. This trend is likely to be enhanced. Electricity trading volume has been increasing rapidly as gross bidding in which traditional electric utilities release some electricity for intragroup transactions to the market has been introduced along with indirect auctioning that subjects bilateral trading through grid interconnection lines to trading via the exchange.
