Two power deals this week show why data centers are building their own power plants — and why gas turbines are sold out through 2030
Brookfield increased its fuel-cell financing with Bloom Energy fivefold to $25 billion, and National Grid put $1.75 billion into a company building on-site gas plants for data centers. Both are routing around a grid interconnection queue that now averages 4.5 years — and both point to a new construction niche with its own procurement risk.
Grid interconnection now takes an average of 4.5 years from request to commercial operation, according to Lawrence Berkeley National Laboratory — and more than 2,060 gigawatts of generation capacity is sitting in U.S. interconnection queues, more than the country's entire installed power fleet. Two deals announced this week show how developers are routing around that wait: they're financing their own power plants instead. For contractors, that's a new, fast-growing scope of work with its own supply chain risk.
What actually happened this week
Brookfield and Bloom Energy expanded their fuel-cell financing partnership from $5 billion to $25 billion on June 30 — a fivefold increase, funded through Brookfield's $100 billion AI Infrastructure Fund. The money backs deploying up to 1 gigawatt of Bloom's on-site fuel cells across Brookfield's AI data center assets worldwide. Fuel cells run on natural gas but generate power electrochemically rather than by combustion, and they can be manufactured and installed in modular units faster than a custom gas turbine can be built and shipped.
Separately, National Grid Ventures announced a $1.75 billion investment for a 35% stake in Joulent, a platform built specifically to develop integrated on-site power for U.S. data centers. Joulent's flagship project, Project Kilby in West Texas, is already moving: a 20-year power purchase agreement with Microsoft, majority GE Vernova turbines with additional Solar Turbines equipment from Caterpillar, a targeted final investment decision by the end of 2026, and first power expected in 2028. The 2.67-gigawatt project is structured to bypass the local grid entirely, drawing on stranded natural gas from the Permian Basin instead.
Both deals are the same bet: interconnection is too slow, so build the power plant on-site and skip the queue.
Why gas turbines are the bottleneck now
The equipment that makes this possible is itself in short supply. GE Vernova's gas turbine backlog hit 100 gigawatts in the first quarter of 2026, with about 20% of that tied directly to data center orders. The company's annual manufacturing capacity is roughly 10 gigawatts — meaning the current backlog represents close to a decade of output. Turbine prices have climbed about 300% over the past three years as hyperscalers compete for open production slots.
That's the reason Bloom Energy's fuel cells are getting a fivefold increase in financing right now: when the turbine you want is sold out until 2030, a fuel-cell array you can manufacture and install in modules becomes the faster path to power, even if the gigawatt-for-gigawatt output is smaller.
What this means for a contractor bidding this work
| If you're bidding... | The scope now includes |
|---|---|
| Site civil / foundations | Turbine pads, fuel-cell array foundations, and fuel-line trenching separate from the main building footprint |
| High-voltage electrical | Interconnection between on-site generation and the data center's switchgear — a different scope than utility service entrance work |
| Mechanical / balance of plant | Fuel supply systems, exhaust and emissions equipment, cooling for the generation equipment itself |
| Precon / estimating | Equipment lead time is now the critical path, not labor availability — confirm turbine or fuel-cell delivery dates before committing to a schedule |
This is a distinct bid package from the data center shell and core. A GC or specialty sub that's only scoped switchgear and UPS systems inside the building hasn't scoped the power plant next to it — and on projects like Kilby, that power plant is now the larger, longer-lead piece of the job.
The honest limit
None of this is confirmed work for a specific contractor — these are financing and equipment deals, not construction contracts, and the companies involved (Brookfield, GE Vernova, Chevron's Energy Forge One subsidiary, Joulent) are assembling their own build teams for flagship projects like Kilby. What it signals for a mechanical or electrical sub is the shape of the opportunity: on-site generation is becoming a standard, budgeted line item on data center campuses, not a one-off workaround. If your firm already does critical-facility electrical or industrial mechanical work, this is the adjacent scope to ask a data center client about directly.
We've tracked this trend from the FERC order pushing grid operators to reform interconnection rules and identifying co-location as a formal reform category — these two deals are the capital that reform was anticipating, moving ahead of any rule change.
Forward this to the estimator or business development lead at a mechanical or electrical sub who's only been pricing the building, not the power plant next to it.

- Why are data center developers building their own power plants instead of connecting to the grid?
- Grid interconnection now takes an average of 4.5 years for a project to go from request to commercial operation, according to Lawrence Berkeley National Laboratory, and over 2,060 gigawatts of generation capacity is stuck in U.S. interconnection queues. On-site, or 'behind-the-meter,' generation lets a data center start drawing power without waiting for a utility interconnection.
- What did Brookfield and Bloom Energy announce?
- On June 30, 2026, Brookfield and Bloom Energy announced they expanded their fuel-cell financing partnership from $5 billion to $25 billion — a fivefold increase — funded through Brookfield's $100 billion AI Infrastructure Fund. The deal supports deploying up to 1 gigawatt of Bloom's on-site fuel cells across Brookfield's AI data center portfolio.
- What is National Grid's $1.75 billion investment in Joulent for?
- National Grid Ventures is investing $1.75 billion for a 35% stake in Joulent, a platform building integrated on-site power solutions for U.S. data centers. Joulent's first major project, Project Kilby in West Texas, will deliver 2.67 gigawatts to a Microsoft data center using GE Vernova and Solar Turbines equipment, targeting first power in 2028.
- Are gas turbines really booked out to 2030?
- GE Vernova's gas turbine backlog reached 100 gigawatts in the first quarter of 2026, with roughly 20% tied to data center orders. The company's annual production capacity is around 10 gigawatts, meaning the backlog represents close to a decade of output, and turbine prices have risen roughly 300% over three years.
- What construction work does on-site power generation create?
- Behind-the-meter power plants require civil and foundation work for turbine or fuel-cell pads, high-voltage electrical interconnection between the generation equipment and the data center, fuel supply infrastructure for gas turbines, and balance-of-plant mechanical work — scope that's distinct from the data center building itself and is typically bid separately from the shell and core contract.
