What this figure does and does not include

Transcription notes recorded when this tariff was encoded, including anything deliberately left out.

• DELIVERY ONLY. Schedule R prices distribution; generation and transmission come from Rider 'SOS' - a separate tariff page with its own rates - or from a competitive supplier. The District's own availability clause says so, and the DC Commission stated it directly in Order No. 22869: 'The Commission only sets rates for the distribution portion of a customer's bill.'
• ONE EIA COMPANY, TWO REGULATORS. EIA files Potomac Electric Power Co as a single operating company across the District and Maryland, and coverage counts per company, so encoding one jurisdiction alone would have marked all 872,387 customers covered. Both are encoded, so there is no overstatement to declare - the same arrangement as Appalachian Power.
• THE ENCODED RATE IS THE DISTRIBUTION SERVICE CHARGE, NOT THE WHOLE DELIVERY LINE. Schedule R names 18 applicable riders and prices almost none of them: Pepco publishes their values on separate monthly and annual sheets, which is why its own summary sheet lists them as 'view monthly rate' instead of a number. Every one is listed in _provenance.excluded_riders. A real bill's delivery portion is HIGHER than this by whatever those sheets currently say, so treat this as a floor.
• WHY NOT FOLD IN THE FEW RIDERS THAT ARE PRICED IN THE BOOK. Because the result would be neither the tariff's distribution charge nor a bill's delivery charge, and no caller could tell which they had. All riders are out, uniformly, and enumerated.
• pepco.com IS A SOFT-200 CATCH-ALL and cannot be used to test whether a document exists. Every HTML path there - including deliberately bogus ones - returns the same empty shell with HTTP 200. The tariffs are on Contentstack behind a reverse proxy at pepco.com/cdn/assets/v3/... that looks first-party by hostname, and every URL is version-pinned: the versionless Contentstack handles return empty bodies, so there is no 'current' alias to follow.
• THE RIDER LISTS NEARLY MATCH IN PLACES, WHICH IS THE TRAP. Only four riders carry EXACTLY the same name in both jurisdictions - Standard Offer Service, Administrative Credit, Optional Meter Equipment Related Services and Bill Stabilization Adjustment. Three more are the same thing under names that differ by a word: the District's 'Delivery Tax' is Maryland's 'Delivery Tax Surcharge', 'Net Energy Metering Rider' is 'Net Energy Metering', and 'Residential Direct Load Control Rider' is 'Residential Direct Load Control'. Near-identical names on separately filed riders are how a value gets carried across and applied to the wrong jurisdiction.
• SEASONS ARE JUNE THROUGH OCTOBER AND NOVEMBER THROUGH MAY. Both tariffs define them identically, and each states them separately - checked against one another rather than carried across, since almost nothing else about these two jurisdictions matches.
• RATE YEAR 2 IS THE ONE IN FORCE, and the schedule prints both. Rate Year 1 ran 1 January to 31 December 2025 at $17.09 and 4.895c; Rate Year 2 runs 1 January to 31 December 2026 at $18.09 and 5.659c. Rate Year 1 is the LEFT-HAND column and is labelled with a year that has already begun, which makes it the easy thing to read by mistake.
• BLOCKED AT 400 kWh, and the first block does not vary by season - 1.982c in both summer and winter. Only the tail differs: 5.659c against 3.952c. So a District bill below 400 kWh is identical in January and July, and the season only bites above that.
• THE RATES ARE UNDER LEGAL CHALLENGE, WHICH DOES NOT MAKE THEM WRONG. DCPSC Order No. 22869 records that on 5 March 2026 the D.C. Court of Appeals vacated Order Nos. 22328 and 22358 - the Formal Case No. 1176 orders that set these two rate years - and remanded. Reporting indicates the rates remain in effect pending remand with no refunds ordered. They are what is billed today; they may not survive the proceeding.
• THE DC COMMISSION PUBLISHES A BILL CALCULATOR AND IT IS NOT USABLE AS A CHECK. dcpsc.org's calculator is headed 'Rates as of July 30, 2026' and computes its figures in JavaScript, so the rate values do not come through a fetch - only the line-item skeleton does. That skeleton is still worth something: it fixes the order of a District residential bill and shows a 'Mayor's Energy Surcharge Fund' line that Schedule R's own applicable-riders list does not name.
