Pepco/Delmarva outline Loadseer forecasting, enhanced hosting‑capacity maps and conservative NWS screening
Summary
Pepco and Delmarva told the Commission they have implemented Loadseer (hourly forecasting), are rolling out power‑flow‑based hosting‑capacity maps, and currently screen non‑wires solutions for larger, longer projects; Pepco/Delmarva said many forecasted constraints were most cost‑effectively resolved by load transfers in their territories.
Pepco and Delmarva representatives described improvements in localized forecasting and hosting‑capacity analysis intended to support integrated electric system planning.
Dan O'Connor, Pepco senior manager for smart grid innovation, said Loadseer provides hourly 8,760‑hour forecasting and enables scenario comparisons for electrification assumptions. He said Pepco and Delmarva have begun transitioning hosting‑capacity outputs from feeder‑level calculations to power‑flow‑based nodal and sectional values and are publishing monthly updates for developers.
Abdul Rahman Kagbo and John Budd outlined PHI's non‑wires screening and planning criteria. Budd said Pepco and DPL identified 28 short‑term constraints but that load transfers, phase balancing and conventional upgrades were usually the most cost‑effective near‑term remedies. He told the Commission that, for the constraints identified in the current 10‑year forecast, "No non wire solutions pass screening criteria at Pepco and DPL for any of the grid constraints identified." PHI urged continued operational pilots (DERMS, VPPs, Drive) to capture measurement and dispatch experience before scaling NWS selections.
