WEC Energy Group, Inc. (WEC) | The Buildout — AI Infrastructure
The Verdict
WEC Energy Group is a regulated utility holding company. Its Wisconsin subsidiaries generate and distribute electricity and natural gas, and it holds a majority stake in ATC, a transmission company operating across four Midwestern states. The AI buildout reaches WEC through power, not products: hyperscale data centers inside its Wisconsin territory need electric capacity, transmission, and generation reliability, and WEC is the utility that must deliver them. Management has designed a very-large-customer tariff so those customers pay their full share of cost and post collateral — the mechanism that lets WEC fund a large build without stranding its existing customers.

What We Like
- FY2026 EPS guidance of $5.51–$5.61 was reaffirmed on both the Q1 and Q2 2026 calls, assuming normal weather.
- The $37.5B five-year capital plan was reaffirmed, and management says the Q3 refresh drivers — corridor growth, a third customer, transmission, Point Beach — are 'all upside.'
- WEC expects roughly 15% of its asset base to be dedicated to very large customers by 2030, a company disclosure stated on both calls.
- The VLC tariff written order arrived in May 2026, with ROE of 10.48%–10.98% and a 57% equity ratio; all three rating agencies called it 'really good.'
- The dividend rose 6.7% in January 2026, a 23rd consecutive annual increase, consistent with a 6.5%–7% growth plan.
What We’re Watching
- Oracle sits at BBB-, the collateral trigger in the PCAs, while the tariff requires A-. A court case over the requirement is ongoing and management gave no timeline.
- A third very-large customer (400–500 MW size) was hoped for by the Q3 call at the prior period and has not been announced.
- FY2026 weather-normal electric sales excluding the iron ore mine and VLCs are guided 'relatively even with 2025,' softened twice from ~1.6%.
- Illinois pipe-program 2026 spending was reduced for labor, and the ATC line decision slipped from fall 2026 to end of 2026.
The investment case is a data-center-load story layered on a regulated utility: a $37.5B capital plan with management-stated upside, roughly 15% of asset base tied to very large customers by 2030, and a 7%–8% EPS CAGR whose acceleration to the upper half from 2028 depends on this build. The base is soft — non-VLC electric sales guide 'relatively even,' and weather-normal gas deliveries fell in Q1. The thesis reads intact but back-end loaded: reported growth in 2026–2027 is modest, and the payoff sits in 2028–2030. The open question is whether the promised third customer signs and whether Oracle's credit support resolves on schedule.
Earnings Beat
In Q2 2026 WEC reported revenue of $2,062.1M, gross margin of 73.1%, and EBITDA of $817.7M, or 39.7% of revenue. Net income was $299.5M, and EPS of $0.91 was up $0.15 year over year. Grid-based growth contributed $0.13 to earnings, including $0.09 of incremental AFUDC equity and $0.02 of incremental cash returns, mostly from projects supporting the VLC customers.
| Metric | Q2 FY2026 | Q1 FY2026 | Q2 FY2025 | YoY |
|---|---|---|---|---|
| Revenue | $2.1B | $3.4B | $2.0B | +2.6% |
| Gross margin | 73.1% | 59.5% | 41.9% | +3120bps |
| EBITDA | $818M | $1.4B | $774M | +5.7% |
| EPS | $0.91 | $2.45 | $0.77 | +18.9% |
| Weather-normal retail electric deliveries | +4.2% | n/a | +4.2% | +0.0% |
as long as their BBB- or worse, they would need to post collateral… we are actually one layer better protected.— Liu Xia, Chief Financial Officer, 2026-07-29
Management tone: Management's tone stayed expansionary on data-center growth while becoming more precise on risk. Versus the prior call, disclosure moved from an aggregate ~3.9 GW of in-plan VLC load to an explicit split (Microsoft 2.6 GW through 2030; Vantage 1.3 GW in forecast, 3.5 GW potential). Oracle's credit and litigation went from absent to the first analyst question, and management separated the physical project ('on time, it's on budget') from the credit issue. They were candid on execution friction — labor slowing Illinois pipe work, a softer non-VLC sales guide — and deferred Point Beach, the Microsoft megawatt update, and repowering detail to the Q3 call. Confidence on the ATM funding program was stated plainly.
Management Guidance
FY2026 EPS guidance of $5.51–$5.61 was reaffirmed on the Q2 2026 call, assuming normal weather for the rest of the year. Q3 2026 EPS guidance was initiated at $0.92–$0.98, accounting for July weather and assuming normal weather for the remainder of the quarter. The long-term 7%–8% EPS CAGR for 2026–2030 was reaffirmed, as was the expectation to accelerate to the upper half of the range starting in 2028. The five-year capital plan was reaffirmed with a refresh due on the Q3 call, 2026 common equity of ~$1.1B is on track (~$760M locked in 1H), and dividend growth of 6.5%–7% was reaffirmed. The 2026 annual effective tax rate is guided to 5.5%–6.5%. FY2026 day-to-day O&M was guided to +3% to 5% versus 2025 and was not explicitly updated on the Q2 call.
Trajectory
WEC's revenue is seasonal — winter quarters carry more natural gas revenue — so sequential comparisons swing widely: Q1 FY2026 revenue of $3,434.2M gave way to $2,062.1M in Q2 FY2026. The trailing quarters show gross margin expanding by roughly 200 basis points, with operating and EBITDA margins roughly flat. Growth is carried by rate base and construction returns rather than volume. Q1 FY2026 revenue rose to $3,434.2M from $3,149.5M a year earlier, helped by Wisconsin rate orders effective January 1, 2026 and a $4.3M current return earned during construction of VLC-linked resources. The underlying non-VLC utility is guided roughly flat, and weather-normal gas deliveries fell 2.1% in Q1.
The Model
The model's locked projections put FY+1 revenue at $10,380.0M with EBITDA of $4,079M (a 39.3% margin), and FY+2 revenue at $11,020.0M with EBITDA of $4,353M (39.5%). The near term is anchored by the reaffirmed $37.5B capital plan and the rate-base and construction returns already flowing through earnings, including AFUDC equity and current cash returns on projects supporting the VLC customers. FY+2 assumes the data-center build proceeds — the Microsoft corridor ramp, the Vantage site, and whatever the Q3 2026 capital-plan refresh adds on top of the current plan.

What Could Go Right — and Wrong
- A third very-large customer signs in the 400–500 MW band, widening the customer set beyond Microsoft and Vantage/Oracle.
- The Q3 2026 capital-plan refresh converts management's stated 'all upside' drivers — corridor growth, transmission, Point Beach — into booked dollars.
- Microsoft's megawatt forecast is raised at Q3, as management expects 'something a little bit more' on the same acreage.
- Oracle executes updated financial security in line with PSCW requirements, drawing a line under the highest-salience credit item.
- The Vantage site converts toward its stated 3.5 GW potential over time, versus 1.3 GW now carried in the five-year forecast.
- The Oracle project stalls or the credit and litigation thread delays the flagship Vantage expansion, putting its 1.3 GW forecast and 3.5 GW potential at risk.
- The third very-large customer fails to land again, leaving growth concentrated in two named relationships.
- Point Beach replacement costs or timing move adversely, shifting the capex that supports the back-end-loaded growth.
- The Wisconsin or Illinois rate cases come in below request when orders are due at end of 2026.
- Long-lead equipment and labor constraints push in-service dates, since management says the outer-year upside sits in 2030–2031 partly because 'it really takes that long from a supply chain.'
Looking Ahead
The next twelve months run through regulatory and planning gates. The Q3 2026 call is the largest scheduled event: the updated five-year capital plan, the Point Beach replacement decision, the Microsoft megawatt refresh, and the potential third customer all point there. By end of 2026, the Wisconsin rate case, the Illinois rate case, and the ATC transmission line decision are all due. Meanwhile the underlying utility is guided flat, so the reported growth rate depends on how much of the data-center pipeline converts.
- August 7, 2026ATC line testimony due — Written testimony in the transmission case serving the Vantage site.
- Mid-August 2026Wisconsin rate testimony — Staff and intervener direct testimony due Aug 10 and Aug 14.
- Q3 2026Capital-plan refresh — Tests whether data-center and Point Beach upside convert to dollars.
- Q3 2026Point Beach decision — Technology choice and roughly $2B–$2.5B per GW of capital placed.
- End of 2026Wisconsin rate case order — Tests the proposed 4.7% (2027) and 4.5% (2028) base-rate increases.
- End of 2026ATC transmission line decision — Supports a late-2027 first Vantage facility.

The Company
WEC Energy Group is a diversified holding company whose wholly owned subsidiaries provide or invest in regulated natural gas and electricity, renewable energy, and nonregulated renewable energy. It holds an approximately 60% equity interest in ATC, an electric transmission company operating in Illinois, Michigan, Minnesota, and Wisconsin, and at December 31, 2025 it had six reportable segments. The AI buildout matters to WEC because hyperscale data centers in its Wisconsin territory need electric capacity, transmission, and generation reliability, not chips or software — and the direction of the business is now set by very-large-customer load: Microsoft, Vantage/Oracle, and a prospective third customer.
WEC owns and operates its own generation. Its utility fleet includes natural gas plants such as Port Washington at 1,210 MW and the Fox Energy Center at 579 MW, coal units including Oak Creek ERGS at 1,083 MW and Weston at 699 MW, utility wind and solar, and a 99 MW battery storage facility at Paris that completed in June 2025. We Power, part of the non-utility infrastructure segment, designed and built roughly 2,500 MWs of generation in Wisconsin and leases it to Wisconsin Electric. The footprint runs across Wisconsin, Illinois, Michigan, and Minnesota, with transmission held through ATC.
Business Segments
Competitive Landscape
The source material frames WEC's position mainly through its service territory and its tariff. WEC owns the distribution and transmission footprint inside which Microsoft's and Vantage's sites sit, and the VLC tariff locks customers in with 20-year sign-ups and net-book-value collateral. The evidence names three competitors — Alliant Energy, MGEE, and Xcel — cited for Wisconsin and Midwestern utility data-center customer acquisition. Management also frames the VLC tariff as a template other data-center customers can read.
- Alliant Energy (LNT)Named for Wisconsin utility data-center load servicing.
- MGEENamed for Wisconsin utility services and renewable energy assets.
- Xcel (XEL)Named for Midwestern utility data-center customer acquisition and Wisconsin electric service and data-center load.
Supply Chain
WEC sits on the delivery side of the AI build, supplying regulated electric service, transmission, and generation to hyperscale data centers in its Wisconsin territory. The source verifies two counterparties — Microsoft as a customer, NextEra as a supplier — though neither names WEC.
