Tullow described MISO’s role as an independent, not‑for‑profit regional transmission organization that dispatches generation based on short‑run marginal cost and manages a wholesale market that resets every five minutes. He emphasized that MISO does not own generation or distribution assets; member utilities retain ownership and must still complete state permitting and siting for transmission projects assigned to them after MISO’s regional planning approvals.

Key points Tullow presented:

- MISO’s footprint covers roughly 15–20% of U.S. load and includes multiple states; it recorded a new wind output record of about 10.5 gigawatts during a recent cold, clear day.
- Long‑range transmission planning: MISO approved an earlier portfolio (Tranche 1) of regional projects (about $10 billion) and in December its board approved a larger portfolio (Tranche 2.1) with an estimated price tag near $20 billion; MISO projects a benefit‑to‑cost ratio in the range of about 2–3 for that work.
- Interconnection queue backlog: developers have requested very large amounts of capacity (Tullow cited queue volumes in the hundreds of gigawatts), and many projects are waiting for transmission upgrades before they can be interconnected. MISO’s transmission tranches aim to unlock access for those projects.
- Data‑center demand: data centers present new 24/7 loads that can be large and sited in parts of the grid that are thin on transmission; Tullow said adding generation and transmission faster than ever will be necessary to accommodate fast‑moving load additions while protecting consumers. He said data centers generally resist interruptions and sometimes bring onsite backup generation; MISO encourages grid‑connected backup and any flexibility on the load side.
- Market dispatch and costs: MISO conducts an economic dispatch that considers short‑run marginal costs only; renewables and nuclear typically set low marginal costs (renewables often near zero), while gas and coal frequently determine marginal prices depending on commodity markets and pipeline constraints.
- Reliability scenarios: Tullow highlighted multi‑day and multi‑hour “wind droughts” (periods with little wind generation) as planning scenarios that require dispatchable or long‑duration resources and reserves.
- Cybersecurity and geomagnetic risk: MISO devotes substantial staff resources to cybersecurity and monitors space weather to prepare for geomagnetic disturbances; Tullow said the organization has been successful to date in defending systems but described geomagnetic events and EMPs as high‑impact risks that require monitoring and preparedness.
- Tools and alternatives: Tullow supported non‑transmission options such as demand response, virtual power plants, batteries and grid‑enhancing technologies as useful pieces of the overall solution, but said most transmission owners must evaluate and implement those options locally.

Committee members asked about congestion costs, how MISO accounts for environmental externalities (Tullow said MISO’s dispatch does not incorporate externalities, only short‑run marginal cost), how interconnection queue management differs from other regions (ERCOT’s single‑state model differs materially), and where value from RTO membership accrues to consumers (MISO estimates billions in benefits and reserve sharing advantages). Tullow also pointed committee members to MISO’s public data on misoenergy.org.

The briefing underscored tensions between rapid load growth in parts of the footprint, long lead times for high‑voltage transmission projects, and the need to maintain reliability via a diversified portfolio, market design adjustments and grid upgrades. Members requested further briefings and indicated bills on related topics may follow.","mediaType","Video","parentTitle","House Energy Finance and Policy Committee 2/18/25","oneSentenceSummary","Brian Tullow, Midcontinent Independent System Operator executive director for the North Region, briefed the Minnesota House Committee on Energy Finance and Policy on regional grid operations, multi‑billion‑dollar transmission plans, an interconnection backlog of generator requests, and challenges posed by large, continuous loads such as data centers.","taxTitle","2025 Legislature MN, Minnesota","taxId",77817,"location","Minnesota","headline","","shortSummary",{"_33":77,"_35":36,"_37":38,"_39":78,"_41":79,"_43":80,"_45":81,"_47":82,"_49":83,"_51":84,"_53":85,"_55":56,"_57":58,"_59":86,"_61":62,"_63":64,"_65":87,"_67":68,"_69":70,"_71":72,"_73":74,"_75":74},6325027,"House committee advances bill to allow large hydro to count toward renewable energy credits",816,55595,871945,"/Search/View?dp=1&key=2335133-b0c24844c632bb1b3bac213f446f0009&start=55&end=871","https://assets.pipeline.soar.com/2335133-b0c24844c632bb1b3bac213f446f0009/thumbnail_55595.jpg","/articles/6325027/Minnesota/House-committee-advances-bill-to-allow-large-hydro-to-count-toward-renewable-energy-credits","https://secure.pipeline.soar.com/6325027-6b59dd8c37e48beaba1fa7201132d08c/orig.mp4?Expires=1770991073&Signature=gIVGsI6WkAH0~9llCIJkgZhzcHIx7OOr-EhJjPZlw5vO05w6aC6WwgY0RdbNDkuiLSTLlGsbZ27A0G6vt6MgGsS8ohD5Ob-55MPEKh~JQjKWcmZ3SgswcajwweoIUIZfnKW2d3gHgpeEakS9AsPminly5PzMXQgQGXlu-GOCrGKX66OJwpwOSth~30eUhTdvkKniDknr40gpOgLYty~FN8VStxIEDQv9GEp28ZI0JWJC5cSJKpQ5ARqCEzI6in0SizRkim845mKBNqu34EwNaJhdJirnLqeKkEUv~qkAUokyBBCAolziQUmVOrAK3w-K-m2PFfxCNeFzT0jcmaoP9w__&Key-Pair-Id=KUT5TJCACFTXG","The Minnesota House Committee on Energy Finance and Policy voted to refer House File 75 to the General Register, advancing a proposal that would remove statutory language preventing hydroelectric projects larger than 100 megawatts from counting toward the state’s renewable energy system.

Representative Anderson moved the referral and the motion carried after a voice vote. The bill’s author said the proposal would allow policymakers and developers to consider larger hydro facilities as a potential source of carbon‑free baseload generation and to let those projects be evaluated for eligibility under the state’s renewable energy framework.

Supporters said the change is procedural and would not permit any specific projects without the normal permitting and licensing processes. Joe Hoppe of Otter Tail Power Company told the committee his utility operates five small hydro plants near Fergus Falls that together generate a little more than 3.5 megawatts (about 1% of Otter Tail’s generation), and said Otter Tail currently has no plans for hydro projects over 100 MW. Rachel Stuckey, executive director of the Minnesota Conservative Energy Forum, said modern hydro can provide dependable carbon‑free baseload power and that any new or modified hydro facility would still undergo federal and state regulatory reviews, including Federal Energy Regulatory Commission licensing when applicable.

Opponents and some committee members questioned whether there are any actual proposals that would use the change. Representative Jones and Representative Acum noted they were not aware of any planned Minnesota projects exceeding the 100 MW threshold and described the bill as allowing discussion rather than authorizing construction. Representative Acum asked that the measure be considered by the House Environment Committee because of potential environmental impacts; Representative Anderson said the bill does not change environmental statutes and agreed to speak with the environment committee chair if re‑referral were requested.

Representative Anderson renewed his motion to send House File 75 to the General Register; the chair called the voice vote and announced that the ayes prevailed. The committee did not adopt any amendments on the floor.

The bill will appear on the General Register, where it may be re‑referred to another committee for additional review. The committee made no formal findings about environmental impacts or the existence of any concrete >100 MW hydro proposals during the hearing.","The Minnesota House Committee on Energy Finance and Policy voted to send House File 75 to the General Register after a debate on whether to lift an existing 100-megawatt size limit that prevents larger hydroelectric projects from qualifying for renewable energy credits.","actionData","errors"]
