What is time to power?

Time to power describes the timeline from when a facility requests electricity until it actually receives access to operational power. Many factors can influence this timeline, such as queue position, infrastructure upgrades, permitting, and equipment lead times, among others.

How long does it take to get grid power for a data center?

There is no national standard or dataset tracking how long large-load connections take, so the wait time will vary. Depending on the region, it can take five to seven years to receive power after making a request. That said, the ERCOT Batch Zero application was submitted in July 2026 and it’s expected to reach a transmission plan by fall 2027 — just 15 months.

What permits does onsite generation need?

Onsite generation usually requires a combination of permits, associated with air quality, environmental factors, zoning, and building, mechanical, and electrical requirements.

Time to Power and the Benefits of Hydrogen Fuel Cells

Time to power is how long it takes a commercial, manufacturing, healthcare, or IT facility to receive electricity after making a request for itDue to the amount of time it takes for planning, permitting, and infrastructure upgrades, construction usually outpaces the availability of an electrical grid connection, which means facilities are often left waiting years before receiving power. In other words, time to power is a crucial metric for how long it takes new facilities to begin operating and generating revenue.

Time to Power, Defined

Time to power is defined as the elapsed time from when an infrastructure component requests electricity until it receives operational power. For grid-supplied power, a lot contributes to how long this process takes, including studies, queue position, upgrades, permitting, equipment lead times, and commissioning. And this timeline doesn’t even factor in shell construction (the building of the physical structure), which typically takes 18 to 24 months.

When addressing time to power, the terms “speed to power” and “interconnection timelines” often enter the conversation. All three describe the same delay; they simply measure it in different ways.

It’s also important to note the distinction between load interconnection and generator interconnection. Load interconnection is the process of connecting a data center or other facility (a load) to the power grid, while generator interconnection is the process of connecting power sources (like a wind turbine) to the grid. When you hear the “five-plus-year” interconnection figure, it’s usually referring to the amount of time it takes to connect generators to the grid — not large loads waiting to receive power. Still, the time to power for large loads can be significant.

What constitutes a “large load?” It varies depending on utility and region. Dominion defines it as at least 25 MW, the Department of Energy considers it to be more than 20 MW, PJM uses at least 50 MW, ERCOT uses at least 75 MW, and Georgia Power uses at least 100 MW.

Why Time to Power Became the Binding Constraint

The demand for energy is accelerating faster than infrastructure can keep up.

In 2025, U.S. data center power demand was roughly 34 GW, but demand models now project 81-114 GW by 2030. As demand continues to increase, grid operators are having to revise their timelines.

For instance, ERCOT’s data center demand is projected to rise from 29 GW to 77 GW by 2030. PJM is adjusting its projections, too, predicting an average annual growth rate of 3.6% over the next 10 years, significantly higher than its 0.3% forecast for 2021.

Demand isn’t the only issue. The equipment needed to expand the grid is also facing long lead times: as of Q2 2025, transformers could take roughly 128 weeks to procure; generator step-up transformers could take about 143 weeks; high-voltage breakers could take around 151 weeks. Lead times for some large power transformers have reached as high as 210 weeks.

Generation equipment is also tightening. GE Vernova’s gas turbine backlog grew from 83 GW to 100 GW to 116 GW during 2026, while Siemens executives said turbine lead times can now stretch to “three years or more.”

These pressures aren’t universal, and lead times for some equipment categories have eased, but the broader constraint remains. Data center developers can often construct the physical facility faster than utilities can secure the equipment, generation, and transmission capability needed to serve it.

The bottom line: Increasingly, power availability is what sets the project schedule.

How Long Is the Wait in 2026?

It’s difficult to estimate the time to power wait in 2026 because there is no national standard. The closest thing we can get is the generator and storage interconnection timeline, which is currently a median 61 months (about five years), but again, that doesn’t describe load interconnection.

One of the best examples we have of load-side estimates is ERCOT Batch Zero. Applications began in July 2026, and the target plan is fall 2027 — roughly 15 months to reach a plan before construction.

Market conditions can change the timeline. For instance, in Northern Virginia, there is a seven-year wait for a 50 MW request, while Texas and some regions in the Southeast have shorter wait times.

Changing rules are also influencing timelines. In June 2026, the Federal Energy Regulatory Commission (FERC) issued show-cause orders on six Regional Transmission Organizations (RTOs): PJM, MISO, SPP, CAISO, ISO New England, and NYISO. The preliminary finding questioned whether their existing tariffs for connecting large loads were just and reasonable, potentially signaling further changes down the road.

Even with these estimates, a lot of uncertainty lingers. Utilities now expect the wait for power availability to be 1.5 to 2 years longer than developers anticipate.

Because of this widening gap between what developers expect and what utilities can actually provide, more than 50% of developers report that it is becoming harder to secure power, according to Bloom’s 2026 Data Center Power Report.

The Cost of Waiting

When a building sits without electricity, the company faces lost revenue, production delays, and competitive disadvantages.

But that’s not all — many utilities are now requiring developers to make long-term financial commitments to secure power, such as 80-85% minimum take commitments, 12- to 15-year terms, collateral requirements, and exit fees. Since utilities are investing so much to serve these new developments, these requirements help protect them from financial risk.

The cost of reserving power is increasing, too. In the PJM region, the auction price for power futures jumped from $28.92 to $329.17/MW-day, with Monitoring Analytics estimating that data center demand now accounts for 63% of that increase.

When planning a new development, developers now need to factor in these upfront costs and how long they are financially committed to the project.

Power Is Reshaping Site Selection

According to Bloom’s report, 51% of respondents ranked power among their top three site-selection factors, ahead of fiber, land, and local regulations.

As a result, developers are increasingly choosing sites based on where electricity is most readily available and the time to power is shorter. For instance, Texas is estimated to exceed 40 GW of data center capacity by 2028, while Georgia’s market share is projected to grow 75%. Meanwhile, legacy markets are losing more than 50% of their relative market share, and other regions of the U.S. are expected to gain roughly 21% in market share.

That said, even the areas with readily available power now will eventually feel the constraints as demand continues to increase. That’s why, when faced with power bottlenecks, 61% of developers are more interested in deploying onsite power as their primary strategy — although 12% will still relocate to a new site.

Strategies to Shorten Time to Power

There is no single way to shorten time to power. Successfully doing so depends on the market, load size, and how much flexibility a developer has around location, operations, and power supply.

One option is to locate the facility a market where utilities have more capacity available and interconnection timelines are shorter. But as more data center developers move into those regions, capacity may tighten, and queues can lengthen there, too.

Developers can also look for more flexible ways to connect to the grid. Some grid operators now offer programs that allow large loads to connect sooner in exchange for curtailment or other operating conditions. The Southwest Power Program CHILLS framework, for example, allows qualifying customers to take non-firm service for up to seven years while firm transmission upgrades are completed. Meanwhile, ERCOT has also developed options like PCLR, where customers accept curtailment in exchange for earlier access, and WLPUN, which can allow customers to bring in their own generation to reduce the amount of new transmission capacity required. ERCOT has been explicit that projects may be able to connect faster by bringing generation or making their load more flexible.

Another approach is bridge-to-grid power, where temporary onsite generation supplies a facility while the permanent grid connection is being completed. This is the most common near-term deployment model for developers who want to bring capacity online faster.

But increasingly, onsite power is moving beyond the bridge-to-grid model. Developers are starting to treat onsite power as a part of their permanent infrastructure instead of a temporary workaround. According to Bloom Energy’s 2026 Data Center Power Report, 73% of respondents are actively evaluating or selecting onsite power providers, and roughly one-third of data centers are expected to be fully powered onsite by 2030 — a 22% increase over six months.

Comparing Onsite Power Options

Not all onsite generation technologies offer the same tradeoffs. Gas turbines can provide large amounts of power, but they may face longer equipment lead times and combustion-related permitting. Reciprocating engines are more modular, but they also produce combustion emissions.

Fuel cells, meanwhile, use a non-combustion process. They’re also highly modular and usually benefit from faster, simpler permitting. Bloom Energy’s 2026 Data Center Power Report cites four advantages:

Shorter lead times that reduce time-to-power risk
Lower local emissions, which support faster permitting and greater community acceptance
Scalability and modularity, including the ability to ramp output
Alignment with long-term sustainability objectives, like achieving 24/7 carbon-free energy compliance

Rystad Energy projects 10.4 GW of cumulative data center fuel cell demand from 2026 through 2030, with investment growing to $30 billion by 2030.

Time to Power in Months, Not Years

Bloom Energy’s deployment model is designed to compress time to power significantly. If gas supply and permits are in place, Bloom can deliver 50-100MW in a matter of months. In one documented data center example, Bloom delivered a fully operational system to Oracle in just 55 days — a month ahead of schedule.

Bloom executive Bala Naidu has described the broader deployment range as “anywhere between 90 days to six to nine months”.

Bloom is also working to shorten the time involved with the installation itself. Its Power Connect uses pre-connected, pre-wired, tested components, that Bloom says can drastically reduce installation time.

Onsite Power as Long-Term Architecture

Onsite power is increasingly becoming part of permanent data center architecture rather than a temporary bridge. In Bloom Energy’s Q2 2026 utility survey, 80% of utilities said they view onsite power as permanent infrastructure: 44% as baseload and 36% as supplemental power. Only 15% viewed it as bridge-only.

That’s particularly notable because behind-the-meter (onsite) generation can reduce utility load and revenue, giving utilities little reason to overstate its permanence.

Utilities expect behind-the-meter power to serve 34% of large-load demand by 2030 and 41% by 2035, with 44% ranking time to power as the leading driver. At the same time, next-gen data center designs are moving toward higher-voltage busways and DC architectures, with 60% and 45% of respondents, respectively, expecting adoption by 2028.

That change also supports incremental growth. Bloom Energy’s data center solutions are purpose-built for 20 MW to 500 MW deployments, allowing operators to add capacity as demand grows rather than build all of it upfront.

Bloom Energy Gives You Control Over Time to Power

Time to power is no longer just a utility planning issue. It can determine where facilities are built, how quickly they begin operating, and how fast companies can scale.

Bloom Energy’s onsite power solutions are designed to give operators more control over that timeline. With modular systems that can scale from tens to hundreds of megawatts, Bloom can support both near-term deployment and long-term growth. Its fuel cell technology delivers reliable, resilient power with a compact footprint, a non-combustion design, and quicker time to power.
