The New York State Public Service Commission has authorized National Grid to provide its customers with a $32 million temporary credit to offset an increase in electric supply costs.

The surge, expected in February, would result in bill spikes for upstate residential and small business customers.

The PSC says without taking immediate action, some of National Grid's customers would have seen above average increases in the month ahead.

Electricity prices could increase by as much as 27% in February.
