In May 2024 Solarpack signed Meta up for two solar projects in Indiana, with the output earmarked for Meta's data centres in the state. It was one of more than a dozen US power deals Meta struck that year. Measured one way the pair adds up to 281 MW. Measured another it is 210 MW. Either way, it lands in the same place in Meta's 2024 table.
Key takeaways
- Solarpack, now Zelestra, announced on 10 May 2024 that it had signed agreements with Meta for two solar projects in Indiana, with the power intended for Meta's data centres in the state.
- The two projects, the 81 MW Jasper County solar project and the 200 MW Reclamation solar project, have a combined capacity of 210 MWac and 281 MWdc.
- The contracts take the form of long-term Environmental Attribute Purchase Agreements (EAPAs) rather than conventional physical power sales; duration and price were not disclosed.
- Leap records 13 power purchase agreements signed by Meta in the US in 2024, 11 of them for solar, totalling 3,392 MW of disclosed solar capacity.
- At 281 MW, the Solarpack contract ranks sixth of Meta's 11 US solar agreements in 2024, and it would also rank sixth if measured at its 210 MWac rating.
What did Meta actually contract from Solarpack?
Meta contracted the environmental attributes of two Indiana solar projects, tied to its own nearby data centres. An Environmental Attribute Purchase Agreement, or EAPA, is a contract to buy the clean energy credentials of a project's output, the certificates that let a buyer claim it is using renewable power. It does not necessarily mean the buyer takes physical delivery of the electricity.
The projects are Jasper County, at 81 MW, and Reclamation, at 200 MW. Both are in Indiana, in the MISO power market, the grid operator covering much of the US Midwest. Solarpack and Meta describe the aim as advancing carbon-free generation close to Meta's data centre operations.
The deal also lands in a state where renewables are still a small share of supply. Leap's record notes that Indiana's renewable energy output is currently about 10 percent. New projects of this size add to that share and bring jobs and community benefits, according to the companies.
Why do the two capacity figures differ?
Because solar plants are measured at both ends of the inverter. MWdc is the rated output of the solar panels in direct current. MWac is what the plant can actually export to the grid in alternating current after the inverters. Developers routinely install more panel capacity than inverter capacity, so the dc figure is higher.
Here the gap is 71 MW, or about a third more panel capacity than export capacity. Leap records the contract at 281 MW, matching the dc figure and the sum of the two project ratings. Comparisons with other offtake deals should keep that in mind, because some contracts are quoted in ac and some in dc.
In this case the choice does not change the ranking. Measured at 210 MWac, the Solarpack pair still sits above Pine Gate's 204 MW Limewood Bell contract and below ENGIE's 260 MW Sypert Branch deal.
How does the deal rank among Meta's 2024 US contracts?
It sits in the middle of the table. Enerdatics records 13 power purchase agreements signed by Meta in the US in 2024. Eleven are for solar, one is for a 150 MW geothermal project with Sage Geosystems, and one is with Entergy for gas-fired stations. The 11 solar deals add up to 3,392 MW of disclosed capacity.
Ranked by capacity, Meta's 2024 US solar contracts run as follows: Invenergy at 760 MW; Longroad Energy and DESRI at 400 MW each; RWE at 374 MW; Arevon's Kelso project at 349 MW; Solarpack at 281 MW; ENGIE's Sypert Branch at 260 MW; Pine Gate's Limewood Bell at 204 MW; Portland General Electric's Tower project, shared with QTS, at 166 MW; rPlus Energies' Pleasant Valley 2, shared with Idaho Power, at 125 MW; and Arevon's Heirloom at 73 MW.
Six of the 11, including Solarpack's, sit in MISO, together accounting for 2,237 MW. Only two of Meta's 13 US contracts in 2024 disclose a duration, and none discloses a tariff.
What does the deal signal for US corporate solar buying?
The first signal is concentration. Meta signed solar deals in every quarter of 2024 Leap records, and the pace picked up at the end of the year, with six solar contracts announced between 31 October and 23 December alone. A buyer moving at that speed is effectively a market of its own for developers with projects near its data centres.
The second signal is structure. Solarpack's agreements, like Arevon's Kelso contracts with Meta in Missouri, are written as environmental attribute agreements. That lets Meta match the clean energy claim to a specific region without necessarily taking the power itself. For developers, it means the revenue from the contract may cover the attributes while the electricity is sold elsewhere.
The third signal is opacity. Across Meta's 2024 US deals, Leap captures capacity in most cases but almost never duration or price. Developers and lenders can see who is buying and how much. They cannot easily see what Meta pays, which leaves pricing to be inferred from the financings that follow, such as the debt and tax credit sale behind Matrix's Pleasant Valley project in Idaho, another Meta-contracted plant.
Frequently asked questions
Which projects are covered by the Solarpack and Meta agreements? The 81 MW Jasper County solar project and the 200 MW Reclamation solar project, both in Indiana, with a combined 210 MWac and 281 MWdc.
What is an Environmental Attribute Purchase Agreement? It is a contract to buy the renewable energy credentials of a project's output, which lets the buyer claim clean power use, without necessarily buying the physical electricity.
How many US power purchase agreements did Meta sign in 2024? Leap records 13, of which 11 are for solar with a combined 3,392 MW, one is for geothermal and one is for gas-fired generation.
