THE market operator of the Wholesale Electricity Spot Market (WESM) is expecting spot prices of electricity to increase in May, as demand is also projected to gradually rise soon after the enhanced community quarantine (ECQ) is lifted on April 30. In a market report released Thursday, the Independent Electricity Market Operator of the Philippines (IEMOP) said spot prices are projected to average of P6.68 per kilowatt-hour (kWh) in May, while generation capacity is deemed adequate.
