Paper mill in Concord getting charged PSNH's Stranded Cost Recovery Charge on full contract demand of 2,400kW. But plant only runs 16 hours/day weekdays so actual demand much lower. Should surcharge be based on actual or contract demand?
PSNH large customer surcharge error
Alaska has similar stranded cost charges on industrial accounts. Usually based on actual billing demand, not contract demand. Check New Hampshire PUC tariff language carefully.
PSNH's SCRC should be based on actual monthly billing demand, not contract capacity. If they're charging on contract demand that's an error. File complaint with NH PUC.
Connecticut had similar issues with Eversource. Utilities sometimes default to contract demand for ancillary charges when they should use actual demand. Usually easy fix once identified.
Document actual vs contract demand for past 12 months. Calculate overcharge amount. PSNH should correct billing going forward and refund past overcharges. Kentucky utilities do this automatically when errors found.
Check if other surcharges have same issue - transmission, distribution, renewable energy charges. Often when one ancillary charge is wrong, others might be too.
Update from similar case - Arizona utility corrected stranded cost billing after we filed complaint. Refund was $28,000 over 18 months. Worth pursuing if numbers are significant.
