In leaflets given to consumers, Panelco III said the excess amount would be converted into rebates that would be reflected in the June and July billings.
But it was not clear yet how much the power distribution utility would return to its consumers. Panelco III has some 200,000 consumers in 16 eastern Pangasinan towns and in Urdaneta City.
Jeline Sales, head of Panelco III’s institutional services department, said the adjustment was being computed by the Philippine Electricity Market Corp. (PEMC), operator of the Wholesale Electricity Spot Market.
On March 11, the Energy Regulatory Commission voided the electricity spot market prices implemented in December 2013 and January this year. It ordered PEMC to recompute the generation charges that distribution utilities had passed on to their consumers.
Sales said about 30 to 40 percent of the generation cost would be refunded for the December billing and about 25 to 30 percent for the January billing.
In December, Panelco III increased its power rate by P5.6 per kilowatt-hour, raising its residential rate from P9.8 per kWh to P15.4 per kWh. The following month, the rate was reduced by only more than P1 per kWh.
Board Member Ranjit Shahani, a Panelco III consumer, said he was happy with the refund but noted that Panelco III might have also miscalculated previous generation costs.
Shahani and his mother, former Sen. Leticia Ramos-Shahani, had asked a local court to issue a temporary restraining order and a preliminary injunction to stop Panelco III from implementing the power rate increase while the petition was being heard.
“This is just a partial refund. They (Panelco III) will refund more in the future,” Shahani said by telephone.
