Graded Moderate and steady on how it connects a new large load. 15 states, 5 actions with sources, reviewed 10 October 2026.
The HILL process, FERC-approved January 14, 2026, is a formal study for loads of 50 MW or more with forecast, disconnect and ride-through requirements.
The HILL rules (January 2026) impose equipment and forecast duties but no collateral or minimum term is described in the file.
CHILLS (effective July 1, 2026) lets a load connect early on curtailable service, and HILL loads must have remote disconnect capability.
The HILLGA study (January 2026) gives paired generation within two substations a defined 150-day review, so co-location is allowed and relatively simple.
SPP's July 20, 2026 report shows a 7.06 percent summer 2026 accredited reserve margin; loads connect early only on curtailable CHILLS service (July 1, 2026).
Scored on rules in force, 1 to 5. 5 is the most regulated. Pending rules set the arrow.
SPP publishes no running HILL queue total. Stakeholders submitted ~30 GW of new large loads for the 2026 ITP (11 GW in 2025 ITP); cumulative 100 MW+ requests since 2020 ~26.4 GW with ~7 GW in executed service agreements. HILL process FERC-approved Jan 2026. SPP 2026 ITP futures: peak 91 GW (Future 1) to 110 GW (Future 2) by 2035 vs 56 GW record peak (Aug 2023); SPP Oct 2025 slide shows 75 GW base and 105 GW including spot loads modoenergy.com Pace: Not found. SPP Aug 2026 status update to MO PSC gives HILL requests (11 requests, 3,871 MW; 568 MW added to service agreements) and no energized figure; SPP blog and Modo give pipeline only.
SPP is the only grid operator with FERC-approved large-load rules already operating: a defined study process for loads of 50 MW or more, a 150-day study for generation built next to them, and a curtailable service that lets a load connect before firm upgrades are finished. FERC used SPP's 50 MW definition as the model for its national show-cause orders. SPP has told FERC its existing framework largely answers the order. The summer of 2026 still brought federal emergency orders for the region.
SPP plans to file a price-responsive load product on or before 16 November 2026 and is refining curtailment rules for its interim service. FERC must still decide whether SPP's existing rules satisfy the show-cause order.

5 items: each is a law, order, tariff, ruling, utility action or local decision that changes what a data center must do, pay or disclose, or where it may be built. Failed and pending measures are marked. Each links to its source.
Orders 202-26-36 and 202-26-37 (20 July to 10 August 2026) authorized SPP to dispatch units beyond normal limits and call on backup generation as a last resort during summer heat.
Source: energy.govEffective 1 July 2026. A large load can take curtailable transmission service and connect on available capacity while firm upgrades are built. Refinements to commitment sequencing and curtailment ramp rates are in development.
Source: climatesolutionslaw.comSPP told FERC in July 2026 that its existing framework already covers large-load resource adequacy and that no immediate overhaul is needed. It is developing a Price Adaptive Load product with a FERC filing targeted on or before 16 November 2026.

A HILL is a new or expanded load of 50 MW or more above 69 kV, or 10 MW or more at 69 kV or below; it must provide added forecasts, remote disconnect capability, phasor measurement units and ride-through. The optional HILLGA study takes 150 days for generation within two substations of the load, which must be in commercial operation within five years.
