(2) The NSPL interval answer is derived: M-2 uses the same customer value (average load at the ComEd Five Peaks) in both the capacity and the transmission formula, and the FAQ confirms ComEd computes that value from individual hourly data; no document states it for NSPL directly. M-2 also says net metered load can produce a negative value.

I did not open a PUCO order confirming this directly (the PUCO docket site rejected automated requests), and the posted Ohio capacity manual is dated 1/1/2013 and only distinguishes hourly metered from monthly metered customers. So 'interval' rests on M-2 plus the stipulation commitment plus one secondary report of implementation.

Rule 5.1.2.B confirms NSPL is 1 CP and PLC is 5 CP. If Duquesne classifies a given AMI home as hourly metered, the answer flips to interval; confirm with the Supplier Service Center before relying on it. Also note an internal inconsistency in the manual: the NSPL text says one peak hour, while the NSPL table says 'five season peak hours for the DLCO Zone' (looks like boilerplate shared with FirstEnergy's manual); the tariff says 1 CP. 2018 supplier FAQ (https://www.customer-choice.com/public/Docs/FAQFeb2018.pdf) Q40: NSPL changes sent first business day of January, PLC changes first business day of June." } ], "source": "https://www.pjm.com/markets-and-operations/billing-settlements-and-credit/theo-plc-and-nspl.aspx" }, "timezone": "Eastern", "energyByKw": { "1": 75.77, "2": 151.54, "3": 227.31, "4": 303.08, "5": 378.85, "6": 454.62, "7": 530.36, "8": 606.09, "0.5": 37.89, "1.5": 113.66, "2.5": 189.43, "3.5": 265.2, "4.5": 340.97, "5.5": 416.74, "6.5": 492.51, "7.5": 568.21 }, "energyExportUsdPerYear": 518.46, "energyMonthly": [ { "month": "2025-10", "usd": 40.01 }, { "month": "2025-11", "usd": 15.53 }, { "month": "2025-12", "usd": 10.6 }, { "month": "2026-01", "usd": 35.34 }, { "month": "2026-02", "usd": 16.57 }, { "month": "2026-03", "usd": 11.46 }, { "month": "2026-04", "usd": 11.89 }, { "month": "2026-05", "usd": 7.07 }, { "month": "2026-06", "usd": 42.67 }, { "month": "2026-07", "usd": 140.1 }, { "month": "2026-08", "usd": 42.5 }, { "month": "2026-09", "usd": 144.72 } ], "energyTopTwoMonths": { "months": [ "2026-09", "2026-07" ], "share": 0.549 }, "peaks": { "zoneOneCP": { "date": "2026-07-02", "localStart": 16, "mw": 2732, "coveredByClock": false }, "zoneFiveCP": [ { "date": "2026-07-02", "localStart": 16, "mw": 2732, "coveredByClock": false }, { "date": "2026-07-01", "localStart": 17, "mw": 2728, "coveredByClock": true }, { "date": "2026-07-03", "localStart": 17, "mw": 2706, "coveredByClock": true }, { "date": "2026-07-15", "localStart": 17, "mw": 2705, "coveredByClock": true }, { "date": "2026-09-02", "localStart": 16, "mw": 2698, "coveredByClock": false } ], "rtoFiveCP": [ { "date": "2026-07-02", "localStart": 17, "mw": 162133, "coveredByClock": true }, { "date": "2026-07-01", "localStart": 17, "mw": 161440, "coveredByClock": true }, { "date": "2026-07-15", "localStart": 17, "mw": 158600, "coveredByClock": true }, { "date": "2026-07-03", "localStart": 17, "mw": 154345, "coveredByClock": true }, { "date": "2026-07-16", "localStart": 17, "mw": 153700, "coveredByClock": true } ] }, "maxRtUsdPerMwh": 3911.7, "hours": 8760, "avgRtUsdPerMwh": 53.43, "hourlyAvgRt": [ 41, 35.95, 32.54, 33.8, 33.09, 38.37, 51.57, 60.76, 42.74, 40.92, 44.57, 43.38, 46.14, 45.47, 47.93, 53.08, 62.54, 81.57, 100.28, 118.55, 82.3, 56.51, 48.15, 41.23 ] }, { "id": "AEP", "utility": "AEP (Ohio, Appalachian, Indiana Michigan, Kentucky, Wheeling)", "states": [ "OH", "VA", "WV", "IN", "MI", "KY" ], "choice": "partly", "choiceNote": "AEP Ohio only", "flags": [], "nitsUsdPerMwYear": 138848.55, "transmission": { "bypassable": false, "note": "The BTCR is charged to shopping and non-shopping customers alike, and AEP Ohio (not the CRES) is billed NITS by PJM for all load, so a supplier cannot keep savings from a lower residential NSPL.", "rider": "Basic Transmission Cost Rider (BTCR), P.U.C.O.
