Matterhorn Energy

Early On-site Power
for Data Centers

10-30 MW of permanent hybrid generation for projects where grid interconnection runs 4-7 years.

What We Do
Power on the timeline of the project, not the grid.
Generation partners across US data center markets.

Grid interconnection timelines in key data center markets now run 4-7 years. Projects are ready, but power isn't.

Mid-size colocation operators, enterprise data center operators, and regional developers face the longest grid delays — their projects sit behind hyperscale projects in the interconnection queue. Matterhorn delivers dedicated on-site generation that brings these projects online on the customer's timeline and stays as a long-term part of their energy mix.

Equipment, engineering contractors, and capital are all available — bringing them together into a hybrid power system on a data center's timeline is the challenge. This is Matterhorn's strength: system design, project finance, deployment, and operations under one dedicated counterparty.

01
10-30 MW hybrid systems
Gas reciprocating engines, battery storage, and solar — sized to roughly 30% of customer load.
02
Years before grid power
Sidestep multi-year interconnection queues with dedicated on-site generation and shorter equipment lead times.
03
Project-specific
Configuration, financing, and contract structure built around each project's load, timeline, and constraints.
04
Phased build-out
Bring 30% of load online years ahead of grid arrival, with the remainder served by grid.
Focus Markets
Markets where the grid is not keeping up.
Focus on PJM, the Mountain West, and the Southeast.

Power demand from data centers is greatly outpacing grid capacity nationwide.

Hyperscalers absorb available capacity, and mid-size data center projects face the longest delays — even in the highest-demand markets. Matterhorn operates in the markets where this structural gap is most severe and where mid-size projects are underserved.

01
PJM (Virginia & Pennsylvania)
The largest data center concentration in the US, with the longest documented grid waits
Dominion Energy communicated 7-year interconnection queues to customers in August 2024 and cannot supply new loads above 100 MW for four to seven years. PPL Electric disclosed a 6 GW load shortfall in its July 2025 SEC filing. Together, Virginia and Pennsylvania hold the largest concentration of mid-size data center projects without near-term power.
02
Mountain West (Utah & Arizona)
Grid relief is years away — without any commitments on when
Rocky Mountain Power has told developers in Utah that no new power is available until 2031, and not guaranteed. Salt River Project and Transwestern delays in Arizona push major Phoenix-metro power deliveries past 2029, with hyperscaler-committed requests absorbing forward capacity. Mid-size data center projects in both markets face indefinite waits.
03
Southeast (Atlanta Metro)
Regional cooperative utilities face major capacity shortages in the third-largest US market
Atlanta is the third-largest US data center market, with grid constraints across both Georgia Power and regional cooperative utilities serving the metro. Greystone Power Cooperative reports approximately 2 GW of data center load in its interconnection backlog. Co-op service territories serve mid-size projects crowded out of traditional utility queues.
04
Texas (ERCOT)
Regulation unlocks behind-the-meter generation — grid queues make it essential
Texas Senate Bill 6, enacted in 2025, created the regulatory framework for behind-the-meter generation serving data center loads outside the standard ERCOT interconnection process. Oncor, ERCOT's largest transmission and distribution utility, faces sustained interconnection queue delays across Dallas-Fort Worth and South Texas. Mid-size projects can bypass grid queues through behind-the-meter structures.
