What the filing saysDelmarva Power (Maryland) -- large-load tariff under PSC Public Conference 72: The Utility Relief Act (signed May 12, 2026) requires every Maryland investor-owned electric utility and electric cooperative to file large-load rate schedules with the PSC. Sources conflict on the filing date: the bill record we read says January 1, 2027, while an October 2026 law-firm commentary says the September 1, 2026 filing deadline has passed and the dispute has moved to the filed tariff sheets (PSC Public Conference 72). The utilities' own tariff terms (minimum bills, contract terms, collateral) were NOT read, so treat contract terms as unknown and confirm with the utility.
