Why Grid Lock Is Fueling the $3 Trillion On-Site Data Center Power Market in 2026

Grid Delays Drive Unprecedented Shift to On-Site Data Center Power

The primary catalyst for the rapid adoption of behind-the-meter (BTM) generation is the failure of public grid infrastructure to keep pace with AI-driven power demand, turning on-site solutions from a secondary option into a primary strategy. This structural shift is forcing data center operators to become power producers to ensure speed-to-market and operational continuity.

• In the 2021-2024 period, BTM generation was largely a supplemental strategy for resilience or sustainability, with operators like Google and Next Era Energy signing large renewable Power Purchase Agreements and companies such as ECL initiating early-stage hydrogen pilots. The approach was often fragmented, designed to augment grid power rather than replace it.
• From 2025 onward, BTM became a core development strategy to bypass multi-year grid interconnection queues and secure power for AI workloads. This is confirmed by a landmark industry survey revealing that expectations for fully on-site powered data centers by 2030 soared from just 1% to 27% in a single year, a direct response to grid inadequacy.
• The technology mix has decisively shifted from a primary focus on intermittent renewables to a pragmatic need for firm power. While on-site solar is still deployed, the 2025-2026 period is defined by a surge in demand for immediately deployable natural gas turbines and strategic investments in clean firm power like Bloom Energy’s fuel cells, which secured a potential $5 billion partnership to power AI data centers.
• The scale of BTM projects has escalated dramatically from single-digit megawatt pilots to entire grid-independent campuses. By the end of 2025, developers had already announced approximately 40 projects representing a combined 48 GW of BTM capacity, signaling a fundamental change in how data center infrastructure is planned and built.

Data Center Power Investments: Billions Flow into BTM Generation to Circumvent Grid Delays

Capital is aggressively flowing into integrated digital and power infrastructure, with major private equity firms and hyperscalers deploying billions to build the on-site generation needed to power the AI expansion. This investment wave is no longer focused on incremental additions but on creating entirely new, self-sufficient power and data ecosystems.

• The scale of investment has exploded from project-level financing to massive platform-level commitments. A prime example is the 2025 formation of a $50 billion strategic partnership between KKR and Energy Capital Partners (ECP), specifically designed to develop integrated data center and power assets in response to AI-driven demand.
• Hyperscalers are now directly financing the development of their own power sources, a significant evolution from the earlier PPA model. Google’s December 2024 partnership with Intersect Power and TPG mobilizes up to $20 billion to create “powered land” with co-located renewable generation, directly addressing power availability as a core constraint.
• The market’s search for clean, firm power has unlocked massive strategic deals for enabling technologies. Bloom Energy’s October 2025 announcement of a $5 billion strategic partnership to supply its fuel cells for AI data centers is a landmark validation of hydrogen-ready systems as a viable, at-scale BTM solution.

• In the 2021-2024 period, data center development was widespread, but power solutions remained largely grid-dependent. The U.S., particularly in regions like Virginia and Texas, was already a major hub, but the strategic focus was on securing grid capacity, not bypassing it.
• Since 2025, the U.S. has become the undisputed epicenter of BTM development, with nearly 48 GW of announced BTM capacity by the end of the year. This activity is concentrated in areas with high data center density and acute grid constraints, such as the Permian Basin, where projects like the 250 MW Sharon AI facility are being developed.
• The BTM model is being replicated in other resource-constrained markets globally. The July 2025 launch of Singapore’s first hydrogen-powered data center by Day One highlights how nations with limited land and grid capacity are adopting advanced BTM solutions like SOFCs to enable digital growth.
• Specific U.S. states are becoming focal points for different BTM technologies. Wyoming is a site for innovative utility partnerships like the one between Microsoft and Black Hills Energy, while California is a testbed for advanced microgrids combining hydrogen and batteries, as demonstrated by the PG&E and Energy Vault project.

On-Site Power Technology for Data Centers: From Mature Gas to Emerging Nuclear

The behind-the-meter technology landscape is bifurcated: mature, fossil-fueled technologies are being deployed at scale to meet immediate needs, while capital-intensive, clean firm power technologies are being validated through strategic corporate commitments for post-2030 deployment. This dual track reflects a pragmatic response to the power crisis, balancing speed with long-term sustainability goals.

• Natural gas turbines and reciprocating engines (TRL 9) remain the dominant choice for immediate, reliable BTM power, shifting from a backup role in 2021-2024 to a primary baseload solution in 2025-2026. The primary constraint has shifted from technology risk to supply chain availability, with reports of shortages of these turbines due to the sudden demand spike from data center developers.
• Solid Oxide Fuel Cells (SOFCs) (TRL 8-9) have crossed the chasm to commercial scale. In the early 2020 s, they were used in smaller, sub-megawatt deployments. Now, companies like Bloom Energy, with over 400 MW installed at data centers and a $5 billion supply agreement, have validated the technology as a primary, low-emission power source, even if initially fueled by natural gas.
• Small Modular Reactors (SMRs) (TRL 6-7) have moved from theoretical concepts to concrete commercial interest between the two periods. While no SMRs were tied to data centers before 2024, Amazon’s acquisition of a campus at an existing nuclear plant and Meta’s formal RFP for new nuclear capacity provided the commercial validation needed to advance the technology toward future deployment.

• If the first wave of large-scale BTM campuses powered by natural gas and fuel cells come online successfully in the next 12-24 months, watch for a flood of similar projects from second-tier data center operators and a further tightening of the gas turbine and transformer supply chains.
• A key signal gaining traction is the transition from natural gas-powered fuel cells to systems capable of running on green hydrogen. Favorable final guidance on the U.S. Treasury’s 45 V tax credit would be a major catalyst. Early indicators like the PG&E and Energy Vault hydrogen microgrid are paving the way for this shift.
• The narrative of relying solely on on-site solar and wind for baseload data center power is losing steam due to the immense cost and land footprint required for firming with batteries. The market is clearly signaling a preference for a hybrid approach that includes a firm power source, evidenced by the rising investment in fuel cells and serious commercial interest in SMRs.
• We could be at the beginning of a fundamental re-integration of power generation and digital infrastructure. The ECP-KKR partnership and Google’s “powered land” initiative suggest a future where data centers are no longer just customers of the grid but are anchor tenants of new, localized energy systems.
