Data centers are one of the most controversial new builds today. They're also constrained by access to power.

Green energy infrastructure startup TAR has just raised a $27 million seed round to provide scalable on-site plug-and-play power infrastructure to data centers with a heavy emphasis on renewable power, Forbes has learned in an exclusive. Given the current state of the public debate around data centers, the technology can’t come soon enough.

“We are building modular, scalable, behind-the-meter energy systems consisting of solar, batteries, wind energy and (for emergencies / long periods of unfavorable weather conditions) simple cycle gas turbines,” co-founder Pat Becker told me via email. “The main premise is being able to provide power 24/7 without relying on the grid at low cost, minimal environmental impact and extremely fast.”

That’s a potential step forward on a number of different levels.

The first is power supply for AI providers. At the recent NY Tech Week, prediction startup Principle ran a simulation of the enterprise AI market. In 110 of 123 possible futures, lack of power was the main constraint on growth: not lacking the right chips, not failing to develop the right models … just lack of power. Global demand for power is set to grow 50% faster than the previous decade, says the International Energy Agency, and China’s green energy revolution has allowed the country to add 543 gigawatts of power capacity – more than the total capacity added by the U.S. in its entire history – in 2024 alone, according to the IEEE.

That’s an issue for global competitiveness in AI.

But at the same time, data centers are becoming one of the most controversial new builds, and for good reason. They can be incredibly noisy – a data center in Dowagiac, Michigan emits a constant and irritating 60-decibel whine in neighboring homeowners’ yards – and that destroys not just property values but quality of life. Perhaps just as bad, data centers are also stealing power from communities. 50,000 Lake Tahoe residents just have to simply find a new power source after NV Energy decided to sell the power to data centers instead.

None of that is good for people. And yet, we all individually are using more and more AI. Companies are fueling demand much more, even firing people to fund their AI addictions.

Texas-based TAR might have a solution for at least some of those challenges.

It starts with providing on-site power so data centers don’t have to take it from residential communities. And that ability to provide onsite power means data centers aren’t as dependent on public grid access, so hopefully they can be built farther away from homes.

I had the opportunity to interview Becker on how TAR might be able to be a part of the solution: providing power that doesn’t rely on already-committed grid power, and making data centers at least somewhat more environmentally friendly.

John Koetsier: You’re focusing on green solutions as much as possible?

Becker: We’re focusing on deployment speed and independent power generation, as little reliance on energy prices, gas prices or similar. Renewable energy works great for this from an energy security perspective and it’s great for the environment too.

John Koetsier: What’s new/different about your model?

Becker: For each power generation method we are using, conventional methods rely on outdated methods and a lot of onsite work. We focus on shifting work to factories where we can pre-wire, pre-assemble, pre-test and pre-commission energy generation methods significantly faster and cheaper. This means that each power generation method we are using requires changes to the deployment sequence.

John Koetsier: How much power will your pilot deliver? How does that compare to planned systems?

Becker: Our pilot site (on our own land) will deliver 10 MW of constant power (24/7). The nameplate capacity of the system is a lot bigger than 10 MW (due to fluctuations in solar and wind capacity throughout the year). We built extensive modeling systems to simulate capacity needs at various planned uptimes. Our first customer deployment will have a 24/7 constant power capacity of about twice that.

John Koetsier: Who are your customers?

Becker: The customer for our first deployment is a large neo cloud. We cannot disclose the name.

John Koetsier: How quickly can you get a site operational? Today versus when at scale?

Becker: Our system reduces onsite work to the absolute minimum and we don’t have to wait to be able to connect to the grid as we never tie into it. We are delivering a 20MW constant IT load system within 3 months. The system is modular and repeatable, we are deploying more than 200MW of constant load in 2027 and several gigawatts of constant load in 2028.

John Koetsier: What’s the strategic value here for the neocloud provider?

Becker: Building behind-the-meter energy systems that don’t rely on gas turbines (which are increasingly hard to get) is an incredibly difficult task - power generation via renewable energy requires securing power electronics, battery and energy management, extensive modeling as well as re-inventing how energy is deployed on-site. There is no one capable of building 24/7 energy systems fast enough. Time-to-token is the measure that dominates the industry now and will continue to dominate, so we will be the fastest on the market.

John Koetsier: How do the economics work out? Better than grid?

Becker: We are not cheaper than the grid, but we are much faster. TAR’s energy system is not affected by interconnection queues, curtailment, lengthy permitting cycles, or slow, labor-heavy on-site work. The pricing on the energy will depend on project to project since varying requirements affect how much system overbuild and thus CAPEX is required. It is not uncommon to see behind-the-meter PPA prices as high as $150-$160 per MWh. We are far below that.

John Koetsier: Does this help with the politics? Data centers aren’t popular these days.

Becker: I believe that there are valid concerns about data centers, pollution and impact on local communities. If you rely on building compute close to the energy grid, chances are you are closer to civilization and the impact on communities is larger. If a data center can be powered off-the-grid, far away from civilization in arid land, closed loop cooling and minimal pollution, the conversation around data centers would change significantly.

John Koetsier: How often do you expect the gas turbines to run?

Becker: This strongly depends on the uptime you are targeting and is a cost trade-off - you can get along with no gas turbines at all but the amount of overbuild needed is significantly higher than with (minimal) gas turbines. We expect to only need gas turbines for a few weeks per year if at all.

John Koetsier: What regions will you target? Will it depend on green energy availability?

Becker: We target sparsely populated areas with inexpensive land throughout the US. Since we don’t need a grid connection, a lot more locations are available to us to develop our system.

John Koetsier: Thank you for your time.
