Settlement Reached Between Ontario, Coral

LCG, Feb. 24, 2003--Coral Energy has paid C$1.6 million ($1.07 million) to Ontario's Independent Electricity Market Operator (IMO), while making "no admission of a breach of the market rules," according to the IMO website.

The settlement marks the largest such voluntary payment by an energy trader to the IMO. Neither Coral Energy nor IMO spokesmen would provide any information about what transactions were related to the settlement. According to Jimmy Fox, a Houston-based spokesman for Coral, the company did not gain financially from its trades, and did not manipulate the market.

The IMO coordinates the balance of demand and supply based on its monitoring of trades. It has investigated 106 trades that failed before execution during last summer, and has ceased looking into 41 of them. At least double the number of trades being investigated failed shortly after Ontario's retail market was deregulated. Retail price caps were imposed following price increases under deregulation that brought political pressure to bear on the government. The caps are due to expire in three years.

Critics of the return to regulation say that the move discourages investment in new generation, and will lead to a supply shortage and the need for Ontario to buy imported electricity at higher prices. The CEO of Atco Power, Nancy Southern, said last year that strong transmission links to the United States could enable new Ontario-based plants to export power profitably across the border.
