Minneapolis-area gas capacity: the main utility states a 3.0% reserve margin for 2026-27

By Sam Strong, Vice President of Business Development, Discovery Energy. Technical review by Tara Dugger, Chief Operating Officer. Published November 2, 2026.

Metro used: the Minneapolis-St. Paul-Bloomington, MN-WI metropolitan statistical area as the federal government defined it on July 21, 2023.²⁶ This page covers Minneapolis and the 161 places that only CenterPoint Energy Resources Corp. (CenterPoint) names in its gas tariff. St. Paul and the 79 places that only Northern States Power Company (Xcel) names are on St. Paul and the Xcel area, and Minnesota Energy Resources Corporation (MERC) is covered there too. Places named by more than one tariff are listed on both pages; the page does not say which utility serves them.¹ The rating rests on CenterPoint's record for its whole Minnesota system.

Key takeaways

Who serves the Minneapolis area?

Places named only in CenterPoint's tariff, by county, for the metro's 13 Minnesota counties. A name on the list does not say which part of the place is served.²⁸

Minneapolis, the largest of these places, is named only by CenterPoint's tariff.⁹ Xcel's own information sheet marks Minneapolis as electricity only.¹⁰ 22 places are named by none of the three tariffs.⁸ The two Wisconsin counties are not covered by the Minnesota tariffs, and we did not read any record of the Wisconsin utilities.¹¹

Served by more than one gas utility; which one depends on the address.

Some places are named by more than one gas tariff, so confirm which utility serves your address. That is 63 entries in the Census place list, and a place that crosses a county line counts once for each county.⁸ The tariffs list places, not streets, and Xcel's tariff also names whole counties. The table shows the twelve largest of the 63 places named by two or three tariffs.²⁹

The twelve largest places named by two or three tariffs. Xcel's sheets are effective 2014; MERC's are Sheets 2.00 and 2.01. A name on a list does not say which part of the place is served.¹²

The other 51 entries are listed in the notes.¹³

Has Minneapolis had gas supply problems since 2020?

The CenterPoint records we checked describe no supply event in the last five heating seasons.¹⁴ The Department's October 2026 comments concern CenterPoint's 2026-27 reserve margin and design day, not an event.⁶ Winter Storm Uri in February 2021 came before that window. We did not check any federal or state event report or pipeline critical-notice archive for the metro.¹⁴

How much spare gas capacity does Minneapolis have on the coldest day?

The margin is thin: CenterPoint's net supply of 1,584,790 dekatherms per day (a dekatherm is a unit of gas energy) exceeds its calculated design day of 1,539,000 by 45,790, or 3.0%.² CenterPoint also holds a physical reserve of 36,000 dekatherms. If that reserve is treated as a requirement, net supply less total requirements is 9,790, or 0.62% by our calculation, and the Department's own table shows 2.98%.⁴ The Department's October 1, 2026 comments conclude CenterPoint has sufficient capacity to ensure firm reliability on a peak day and recommend approving the margin; they are staff conclusions, not Commission findings.⁶ The table sets the margin CenterPoint states beside one recomputed from its capacity and design day figures.²⁷

CenterPoint's forecast reserve margin for its whole Minnesota system, as filed on May 29, 2026. The first row, labeled 2027 in the filing, is the 2026-27 heating season. Source: CenterPoint's design day filing.³

The forecast margin rises in 2027-28 because listed capacity grows: transportation is 1,343,790 dekatherms per day against 1,308,790 in 2026-27, and LNG (liquefied natural gas stored for the coldest days) is 90,000 against 72,000.¹⁵ CenterPoint's exhibit shows two heavy dependencies, and we worked out both shares from the same table. Peak-shaving capacity (LNG, propane and storage) of 276,000 dekatherms per day is 17.4% of total capacity, and Northern Natural Gas winter demand of 1,315,096 is 83.0% of the same 1,584,790 total.⁴

What is driving new natural gas demand?

We found no new large gas load in the records we checked, although several sources could not be read. CenterPoint's planned design day has risen every year since 2017-18 except 2026-27, when it fell by 5,100 dekatherms per day (-0.3%).⁶ We checked EIA's September 2026 generator inventory (the EIA-860M Planned sheet) and found no planned natural gas-fired generator in the metro's 15 counties; it lists only 8 planned rows there, none natural gas-fired.⁷ We also searched Federal Register notices of the Federal Energy Regulatory Commission since January 1, 2025 that name a metro county with a pipeline docket and found none.¹⁶ Data centers: As of October 28, 2026, the official records we searched show no gas-fired plant, pipeline lateral or special gas contract serving a data center on CenterPoint's system.¹⁷ One electric item is separate: on May 18, 2026 the Commission approved safeguards for how Xcel Energy may serve very large electricity customers, which concerns electric service, not CenterPoint's gas system.¹⁸ Nearby: EIA's inventory lists 3 natural gas-fired planned rows elsewhere in Minnesota, not in the metro's 15 counties; this page does not tie them to CenterPoint's system.⁷

Are upgrades arriving in time?

Not yet, on the public record: the added capacity behind the 2027-28 forecast depends on CenterPoint's Northern Lights 2027 election on Northern Natural Gas.⁵ CenterPoint said the election will be included in rate base, with further discussion in its 2026 rate case, and the size of the election is excised as a trade secret. No budget or Commission approval for it appears in the public text. The 2026-27 margin comes before that added capacity.²

Who gets gas first in a shortage?

The public record we read doesn't show CenterPoint's order of curtailment (the order in which gas service is cut back) or its penalties, because we did not read the tariff's interruption terms.¹⁹

Winter and market context

Nationwide. On October 15, 2026, NOAA's Climate Prediction Center put the highest odds of warmer than normal conditions over the upper Mississippi Valley and Great Lakes, among other areas.^B1 EIA's October 2026 Short-Term Energy Outlook says prolonged periods of cold weather could increase withdrawals beyond its forecast.^A2 EIA expects U.S. inventories to enter winter above the five-year average.^A1 Other national figures, on storage, exports and spot prices, are in the notes.³⁰ Around the metro. The metro spans Minnesota and Wisconsin, both in EIA's Midwest storage region, where EIA lists working gas at 1,065 billion cubic feet for the week ending October 16, 2026; we did not read the five-year comparison EIA states.^C1 EIA's citygate tables (prices where pipelines deliver gas to a local utility) list 5.43 dollars per thousand cubic feet for Minnesota and 5.22 for Wisconsin for July 2026, the latest month in the saved tables.^C2 Commodity prices measure cost, not delivery capacity, so they are never evidence of a constraint.^C3 Northern Natural Gas's saved critical notices page shows none, but its list loads dynamically, and the Viking and Great Lakes posting hosts blocked automated downloads, so we could not confirm whether recent winter or critical notices have been posted for the pipelines serving the metro.^D1 The next capture is the early December winter refresh.

Winter weather

The last three winters were all milder than the 1991-2020 normal at the airport weather station in the table below, measured in heating degree days (how far each day's average temperature fell below 65 degrees Fahrenheit).²⁰

Winter heating degree days, November to March, as a share of the 1991-2020 normal (NOAA ACIS; we worked out the shares).²¹

NOAA's outlook issued October 15, 2026 leans above normal for Minneapolis in both November 2026 to January 2027 and December 2026 to February 2027, and it is not a forecast of specific days or of an outage.²²

Policy context

Minnesota Statutes 216H.02 states a goal to reduce statewide greenhouse gas emissions across all sectors by at least 50 percent by 2030 and to net zero by 2050, compared with 2005; it is in effect as published by the Revisor of Statutes on October 27, 2026.^P1 Section 216B.2427, enacted in 2021, provides that a natural gas utility may file an innovation plan with the commission.^P2

What is the outlook for Minneapolis and the CenterPoint area through 2029?

Discovery Energy rates the outlook for Minneapolis and the CenterPoint area natural gas capacity through 2029 as Elevated (confidence: Medium): CenterPoint's own filing states a 2026-27 reserve margin below the 5% thin-margin line, and the public record shows no approved or scheduled fix, which sets the base level at Elevated.² Documented risk factors: concentration, because the Northern Natural Gas share above exceeds the 10% test.⁴ One factor alone leaves the level at Elevated, so that concentration is also a trigger; a second documented factor or another trigger would change the assessment. Expiring supply was not tested, because CenterPoint's Northern Natural Gas contract terms are excised as a trade secret.¹⁹ Peak-shaving capacity is a group of LNG, propane and storage facilities, not one source, so it is not a concentration factor.²³ Three developments would change the assessment: CenterPoint's added capacity, including Northern Lights 2027, shown with a budget or Commission approval, or a different margin in its November 2026 compliance filing; a second documented risk factor, such as a dated supply event or an expiring contract; or the Commission's action on CenterPoint's entitlement petition.⁵

The Federal Energy Regulatory Commission's decision on Northern Natural Gas's proposal to abandon in place about 131 miles of its A and J lines in Iowa and Minnesota is a further trigger for this page and not a risk factor.²⁵ This rating cannot be split by area. CenterPoint's tariff names the most people in the metro but not all of them. The Wisconsin counties, MERC and several smaller systems are not covered, and we did not read the Department's findings on Xcel's design day. Outlook levels, from least to most concern: Stable, Watch, Elevated, High, Severe. Levels describe the public record of capacity and supply risk; confidence is reported separately. They are qualitative assessments, not forecasts of outages.

What's new (as of October 28, 2026)

On October 1, 2026, the Department recommended that the Commission approve CenterPoint's proposed 2026-27 reserve margin. On October 8, 2026, federal staff issued the environmental assessment for Northern Natural Gas's V2F and NL27 projects, which would add 79,303 dekatherms per day of firm service in Minnesota. The notice describes added pipeline capacity rather than new gas load, gives no in-service date and names no data center.²⁴

What should Minneapolis-area facilities check now?

• Tariffs and charges, through a utility audit. Confirm each account is on the right rate class and tariff, and that riders, demand charges and capacity-related charges are billed correctly. Over 70% of the clients Discovery Energy has audited were billed incorrectly. An audit verifies tariffs and charges and recovers overcharges before winter costs rise.
• Which utility and rate. Confirm whether each site is served by CenterPoint, Xcel, MERC, another utility or a municipal system, and which rate class it is on, because several suburbs, including Woodbury, Lakeville, Blaine, Eagan and Shakopee, are named by more than one tariff.
• Backup plans and fuel. Check that alternate-fuel and curtailment plans are current and feasible, and that fuel inventories and resupply arrangements are in place before December, because the thin margin above leaves little room on CenterPoint's coldest planned day.
• Upcoming proceedings. Track CenterPoint's November 2026 compliance filing, its 2026 rate case and the Commission's action on its entitlement petition. Discovery Energy reviews service elections, interruption terms and regulatory proceedings for organizations across the U.S. and Canada, so capacity changes are understood before they reach the bill.

Territory by tariff, written from the three tariffs below against the Census Bureau's Vintage 2025 city and township estimates for the 13 Minnesota counties (331 entries, summing to the county totals). A name on a tariff list means the utility lists the place, not that it serves all of it; spelling and label differences were matched. The county tables on this page are drawn from that file. A place that crosses a county line is listed once for each county, with that county's part of its population. The share of the metro's Minnesota residents who live in places named only in CenterPoint's tariff is 55.1% (Census 2025 estimates).
