The article didn't include the actual power rates. I think the applicable tariff is $3.316/kW of demand + 16.82c/kWh. https://www.scc.virginia.gov/docketsearch/DOCS/89pc01!.PDF

Compared to my local utility (and most of Canada), the demand charge is low, but the per kWh charge is high. NSPower's general tariff is $9.089/kW + 15.738c/kWh for the first 200/mth, and 12.674c/kWh after that. Equivalent rates in Quebec and Manitoba are about half that. https://www.nspower.ca/your-business/save-money-energy/busin...

Current CAD/USD is 0.7, so subtract 30% for NSPower's rates in USD.
