The project enters service in late 2027, meaning procurement decisions for successor projects need to begin now
Decision Focus
Enbridge and Meta have announced the Cowboy Project: a $1.2 billion solar and battery energy storage development near Cheyenne, Wyoming, targeted to enter service by end of 2027. The project pairs 365 MW of solar generation with a 200 MW / 1,600 MWh battery energy storage system, delivering power to Meta through Cheyenne Light, Fuel and Power under Wyoming’s Large Power Contract Service tariff. Tesla will supply and service the battery fleet. For Global Heads of Data Center Energy, the operational signal is not the headline number — it is the tariff mechanism and the BESS tolling structure, which together define a replicable procurement path that most teams have not yet mapped.
90-Second Brief
Today, the Cowboy Project expands Enbridge’s contracted capacity with Meta to approximately 1.6 GW across North America, a portfolio that already includes 600 MW of solar and 452 MW of wind in Texas. Wyoming’s LPCS tariff enables large-load customers to access renewable and market-based energy without shifting cost burden to retail ratepayers, a regulatory condition that keeps utility commissions cooperative. The BESS capacity runs under a separate battery tolling agreement with Cheyenne Light, Fuel and Power under the same tariff, decoupling storage dispatch from the solar generation contract. The project enters service in late 2027, meaning procurement decisions for successor projects need to begin now.
What Is Really Happening?
The standard PPA model — buy electrons, match RECs, report Scope 2 — is no longer sufficient for hyperscalers with 24/7 carbon-free energy commitments and load profiles that peak outside solar generation windows. What the Cowboy Project structure does differently is treat dispatchability as a contracted obligation, not a grid assumption. The tolling agreement gives Meta scheduling control over 1,600 MWh of storage capacity, allowing the operator to shift generation across hours rather than accepting whatever the grid delivers. That is a meaningful operational advance over a simple solar offtake.
The LPCS tariff is the enabling layer. Wyoming’s framework was designed to give large industrial and commercial customers access to custom generation and storage arrangements through their utility, without requiring the customer to take on direct generator risk or navigate FERC-level interconnection complexity independently. For energy procurement teams, the tariff structure lowers the regulatory friction of a behind-the-meter or co-location model while still achieving dispatchability outcomes that resemble one.
Enbridge’s role is also worth examining. The company is primarily known as a pipeline and midstream infrastructure operator, but this project positions it as a bankable developer-owner for utility-scale solar-plus-storage at a capital scale — $1.2 billion in a single project — that only a handful of counterparties can credibly offer. That depth matters when procurement teams are evaluating whether a developer can actually close financing and hit a commercial operation date.
Why It Matters for Global Heads of Data Center Energy
Three implications are direct. First, the tariff mechanism. If your team has not reviewed state-level large-load tariff options beyond ERCOT, PJM, and CAISO, Wyoming’s LPCS is now a documented proof point for what a utility-mediated clean energy delivery structure can look like. The precedent supports conversations with utility partners in other jurisdictions about structuring equivalent frameworks before capacity is committed elsewhere.
Second, the tolling agreement structure deserves attention as a contract template. A tolling agreement on BESS capacity gives the offtaker dispatch control without owning the asset — relevant for teams under budget pressure to avoid capital ownership of storage while still meeting 24/7 CFE matching requirements. The Meta-CLFP structure achieves this under a long-term utility tariff rather than a merchant arrangement, which reduces basis risk exposure compared to a standalone BESS PPA in a volatile wholesale market.
Third, counterparty diversification. Meta’s 1.6 GW Enbridge portfolio spans solar and wind across Wyoming and Texas. If your portfolio is concentrated with one or two developers, the risk from a single delayed COD or financing gap is material. The Enbridge relationship demonstrates that infrastructure-scale energy companies with strong balance sheets are viable developer-owners for this asset class — expanding the field beyond pure-play IPPs.
Forward View
If the Cowboy Project enters service on schedule, it will reach commercial operation during a period when AI-driven load growth is expected to compress available clean capacity in Western interconnections. Teams negotiating PPAs for 2028 and beyond are competing for generation that has not yet been permitted. The 2027 COD on this project reflects development and permitting decisions made years earlier — any project a team wants operating by 2029 or 2030 requires counterparty engagement now.
The Tesla battery supply contract introduces a second vector to monitor. Large-format BESS procurement is increasingly supply-constrained, and a 200 MW / 1,600 MWh battery order of this scale will absorb meaningful manufacturing capacity. Teams planning behind-the-meter or grid-scale BESS additions in the same timeframe should audit their battery supply chain assumptions against committed orders already in the market.
Wyoming as a geography also signals that hyperscaler energy procurement is moving beyond established data center power markets. Cheyenne is not Northern Virginia, Phoenix, or Dallas. If clean energy availability continues to tighten in tier-one markets, expect more procurement activity to follow load into jurisdictions with favorable tariff structures and available renewable resource.
What Is Still Uncertain
The source does not confirm what portion of Meta’s Wyoming data center load the Cowboy Project will cover, or whether the 1,600 MWh BESS is sufficient for hour-by-hour 24/7 CFE matching at the facility level. Battery tolling rights give dispatch control, but the depth of that coverage relative to actual load shape is undisclosed. Similarly, the LPCS tariff structure is Wyoming-specific; whether analogous frameworks exist or can be negotiated in other states is not addressed by this announcement and would require jurisdiction-by-jurisdiction regulatory assessment.
Enbridge’s project finance structure — whether the $1.2 billion is fully on-balance-sheet or syndicated — is also unconfirmed, which affects how the counterparty risk profile reads for long-duration contracts extending to the mid-2030s and beyond.
One Question for Your Team
Which states in your current site pipeline have utility tariff structures equivalent to Wyoming’s LPCS, and have those tariff options been presented to your procurement team as a structured renewable delivery path — or only as a backup if direct interconnection fails?
