Consumers Energy Company, M.P.S.C. No. 14 - Electric. Encoded from the Michigan Public Service Commission's CURRENT rate book files, not the utility's own copy and not the '_canceled_' files the commission publishes alongside them. Michigan rate books carry cancelled sheets in the same series as live ones.
Priced sheets are Ninth and Tenth Revised, issued April 24 2026, effective for service on and after May 1 2026, under MPSC Case No. U-21870.
THE PSCR FACTOR IS ADDED, NOT INCLUDED. The rate sheets say the rate 'is subject to the Power Supply Cost Recovery (PSCR) Factor shown on Sheet No. D-6.00'. Consumers' own explanation: costs above a base amount already inside the energy charge 'are recovered through a Power Supply Cost Recovery (PSCR) factor that may vary from month to month'. $0.01456/kWh is used here, the latest published ACTUAL factor (July 2026). June 2026 was $0.01337 and August was not published in either the rate book or the commission's PSCR summary when this was encoded.
PSCR IS A MONTHLY NUMBER AND THIS ENGINE HOLDS ONE VALUE. A single factor is an approximation of something that moves every month by roughly a tenth of a cent. It is about 6% of the marginal price, so omitting it would be the larger error.
Seven per-kWh surcharges apply on top of energy and distribution, totalling 1.4184 c/kWh: energy efficiency, demand response, investment recovery, financial compensation, rate case deferral, and TWO separate securitization charges - Power Plant (U-17473) and Karn 1 and 2 (U-20889).
THE KARN SECURITIZATION CHARGE EXPIRES. $0.004049/kWh, filed for the October 2025 through September 2026 billing months. It is 29% of the surcharge stack and it lapses within weeks of this encoding.
THE LOW-INCOME ENERGY ASSISTANCE FUND CHARGE IS MID-TRANSITION. Sheet D-3.00 files $1.25 per billing meter for September 2025 through August 2026 and $1.50 beginning the September 2026 billing month. The current $1.25 is encoded; it changes within weeks.
Summer is June 1 through September 30 and winter is October 1 through May 31, stated as SERVICE DATES rather than billing months. Several tariffs in this catalogue use billing months for the same-looking split.
The Renewable Energy Plan Surcharge is filed at $0.00 per billing meter for residential rates and is included at zero rather than omitted, so that it becomes visible if it ever moves.
TRANSCRIBED FROM THE MPSC, WATCHED AT THE UTILITY. michigan.gov answers the monitor's user agent with HTTP 403, so the commission's files cannot be part of the watch list without reporting a permanent failure. The figures here were read from the MPSC's dated, versioned section files - which is why the revision numbers and case numbers above are exact - and the utility's own copy of the same rate book is what the monitor fetches. It carries Sheet D-6.00, so a PSCR change is still detected.
RECONCILED. Energy plus distribution reproduces all three of Consumers' published headline rates - $0.245 on-peak summer, $0.197 off-peak summer, $0.176 winter - which the utility qualifies as excluding PSCR, system access and surcharges. Every energy rate is also summed from its filed Non-Capacity and Capacity components and checked against the Total the rate book prints on the same row.
EXCLUDED: the Income Assistance Credit (-$8.00/month), Low Income Assistance Credit (-$42.00/meter/month) and Senior Citizen Credit (-$4.00/month), all eligibility-restricted, and Michigan state and local taxes.
CAUTION on Consumers' own Summer Rate page: its FAQ quotes off-peak summer as $0.104/kWh, which is the bare energy charge with distribution omitted, contradicting the $0.197 in the body of the same page. The embedded chart images are staler still. The body text is the one that reconciles.
THE STANDARD RESIDENTIAL RATE. Consumers' published explanation: 'Residential Summer On-Peak Basic Rate (RSP) became the standard residential rate beginning January 1, 2020.' The rate book itself never says 'default'; the designation rests on that statement plus rate code 1001, which appears on both the tariff sheet and the customer's bill.
TIME-OF-USE IN SUMMER ONLY. There is an on-peak price between June 1 and September 30 and a single flat energy charge from October 1 to May 31. Treating this as a year-round TOU rate would invent a winter peak that does not exist.
On-peak is Monday to Friday, 2:00 PM to 7:00 PM. Weekends are off-peak.
HOLIDAYS ARE NOT EXEMPT, and the sheet says so: the schedule applies 'Monday through Friday, June 1 through September 30, INCLUDING weekday holidays when applicable'. This engine has no holiday concept, which for once matches the tariff exactly.
Distribution is $0.093333/kWh flat - no tiers, no seasons. Only the energy charge moves.
The summer on-peak energy charge is 1.46x the summer off-peak one, and both sit above the winter flat charge.
NOT ENCODED: Rate RPM, Residential Nighttime Savers (Sheet D-40.00, rate code 1050). Its prices were read, but its Schedule of Hours sits past the point where the rate book fetch truncated, and the only period definitions available came from a marketing page. Encoding a three-period time-of-use rate on hours that were not read from the filed sheet is exactly the mistake this catalogue avoids.
NOT ENCODED: Rate RSM, Residential Service Secondary Non-Transmitting Meter (Sheet D-44.10, rate code 1000). The fetch truncated inside D-44.00, so no verbatim prices were read at all. It also has a summer inclining block at 600 kWh, unlike every other residential rate here.
