Xcel Energy's 2026 Data Center Growth Strategy with Hyperscalers

Xcel Energy’s 2026 plans for hyperscaler data center growth partnerships

Xcel Energy’s 2026 strategy for data center growth partnerships with hyperscalers focuses on (1) executing and expanding signed/near-signed energy service agreements (ESAs), (2) using “large load” tariff/regulatory filings to enable responsible load growth, and (3) leveraging generation + storage + transmission development partnerships to support multi-gigawatt contracting through 2027 and into the early 2030s. ¹²³

1) Execute the Google-driven data center model (and related regulatory work) in 2026

• Xcel described “details” of a “groundbreaking agreement with Google” under a 15-year structure where Google covers the entire cost of its service and infrastructure requirements, including 1,900 MW of new wind/solar generation plus long-duration storage (Form Energy’s “100-hour iron-air battery”). ¹
• Xcel stated the Google ESA includes “credit protections” and estimated that the new data center will save customers $1.0 billion to $1.5 billion over the ESA term. ¹
• Xcel also emphasized operational design aligned with sustainability goals, including limiting water needs via air-cooled technology instead of water-cooled approaches. ¹
• Xcel further stated it “filed that contract with the Minnesota PUC” related to the Google development, and noted that it had already been underway developing solutions for 2 gigawatts of new capacity “with plans to expand in the near future.” ⁴¹

Implication for 2026: management’s messaging indicates 2026 is primarily about building institutional and regulatory precedent for large-load hyperscaler development using the Google template, then scaling the process across additional regions and developers. ¹⁴

2) Apply “large load tariff” mechanics in multiple states starting in 2026 (including Colorado; planning others)

Xcel is using long-term tariff frameworks to structure hyperscaler data center expansion in a way that (per management) protects existing customers and supports state clean-energy goals:

• Xcel said that in Colorado, it “filed our large load tariff… with proposed terms similar in scope” to its Google ESA and Minnesota filing, including long-term contracts, minimum bills, termination fees, credit requirements, and incremental cost tests to protect existing customers. ²
• Xcel stated it planned “similar filings in Texas, New Mexico, and Wisconsin” in the coming months. ²
• Xcel described these tariff efforts as part of ensuring large-load growth “does not increase cost for our existing customers.” ²

Implication for 2026: rather than relying only on one-off deals, Xcel is standardizing the regulatory/contracting “package” so hyperscalers can scale more quickly while the utility retains credit/cost protections through tariff design. ²³

3) Expand the NextEra partnership and pipeline contribution to hyperscaler data center load

While the Google deal is the flagship, Xcel also described a partnership ecosystem with NextEra intended to accelerate data center development across Xcel operating companies:

• In April, Xcel reached a definitive, nonexclusive agreement with NextEra to “co-develop generation, storage, and interconnections” to accelerate data center development across Xcel operating companies. ¹
• Xcel expected this joint development agreement to deliver a mix of company-owned resources and purchase power agreements with NextEra across wind, solar, battery storage, and natural gas. ¹

Xcel linked this pipeline-building to near-term contraction expectations:

• On the “high-probability pipeline,” Xcel expected 4 more gigawatts to be contracted by 2027, and stated that this is “inclusive of the 2 gigawatts we referenced with NextEra.” ⁵
• Xcel also said the NextEra partnership “could be larger than” that embedded amount and described active engagement that “it could be bigger to serve all four.” ⁵

Implication for 2026: management appears to treat 2026 as a year to convert partnership-enabled buildable capacity (generation/storage/interconnections) into additional hyperscaler load commitments, using NextEra as a key co-development pathway. ¹⁵

4) Translate hyperscaler commitments into infrastructure execution: RFPs, transmission, and capacity additions (including 2026 capital spending)

Xcel’s partnerships are not only commercial; they tie directly to infrastructure development required to serve large loads:

• Xcel described incremental infrastructure elements tied to data center development, including the 765 kV Crawfish Draw to Phantom transmission line (allocated by SPP in February), “two-thirds, or over 1,200 MW” of generation and storage needed for the Google project, and 800 MW of generation approved by the Colorado Commission. ⁶
• Xcel also pointed to “active generation RFPs” in PSCO, NSP, and SPS and additional regional transmission investments in SPP and MISO to support data center demand (including 3 gigawatts added to the target plan on the Q4 earnings call). ⁶
• Xcel stated that in the first quarter it invested over $3 billion in new infrastructure and brought online nearly 500 MW of new solar generation and utility-scale battery storage (in SPS and Colorado). ⁶

Finally, management quantified broader economic benefit and pipeline-to-capex linkage:

• Xcel stated it expects customers to see more than $7 billion in aggregate benefits from PTCs and ITCs associated with generation/storage projects across 2026 to 2030. ⁶
• Xcel also referenced that hyperscaler-driven data center contracting (“3 gigawatts”) drives “another 6 to 10 gigawatts” of generation needed, describing this as a “huge long-term opportunity” to extend investment visibility into the early 2030s. ⁷

Implication for 2026: partnerships with hyperscalers are operationalized through a coordinated build program—tariffs/regulatory filings enable load, while the EPC/OEM/developer ecosystem and generation/transmission build-out provide physical capacity. ²⁶³⁸

5) What hyperscaler growth targets imply specifically for 2026 timing

Xcel’s commentary suggests a near-term contracting cadence that begins in/through 2026:

• Xcel stated it expected to “execute on enough ESAs this year to get to a 3 gigawatt target, and another 3 gigawatts next year.” ³
• Separately, Xcel said it expects 4 more gigawatts contracted by 2027 on the high-probability pipeline (inclusive of the NextEra-related 2 gigawatts). ⁵

Implication for 2026: the company’s partnership plan for hyperscalers in 2026 is aligned to contracting at least 3 GW of data center load via ESAs during 2026, supported by the Google and NextEra frameworks and enabled by large-load tariff filings and ongoing infrastructure RFPs/builds. ³⁵²

---

Bottom line (direct answer)

In 2026, Xcel Energy’s hyperscaler data center growth partnerships are centered on scaling a repeatable “large load” development model using (a) execution of the Google 15-year ESA (including Minnesota PUC filing and associated generation/storage/infrastructure), ¹⁴ (b) deploying large load tariff frameworks beginning with Colorado and planned filings in Texas, New Mexico, and Wisconsin, ² and (c) leveraging co-development with NextEra to support additional contracted load (with embedded 2 GW and expectations of broader pipeline contributions into 2027). ¹⁵ Collectively, these efforts are intended to enable contracting on the order of 3 GW in 2026 via ESAs, with additional multi-GW follow-through in 2027 and beyond. ³⁵
