When Even Amazon Can’t Get Power.
Earlier this year, Amazon hit a wall in Ireland. They had plans for another giant data center, but the project never got off the ground. Not because of money, or politics, or red tape — but because they simply couldn’t get enough electricity to power it. The grid couldn’t handle the load.
That story stuck with me. To me, it feels like a preview of what’s coming. Over the next couple of years, I think we’re heading into a serious electricity crunch. The signs are everywhere. Human population is at an all-time high — and just imagine how much more power will be needed five or ten years from now to sustain daily life. At the same time, AI systems are multiplying, humming day and night inside new data centers. Add millions of EVs charging in garages, and it’s clear the grid is already stretched to its limits.
If I’m right, we could be living through rolling blackouts in places like North America and Europe. This isn’t some distant problem — it’s a real risk taking shape right in front of us. And if you need a preview of what that looks like, just look back to April, when Spain and Portugal lost power for 12 hours, leaving millions without electricity through the day.
Mega-cap tech companies see this problem too. They’re spending billions to secure their own future power supply — building solar farms, signing long-term energy contracts, even exploring nuclear. At the same time, they’re investing heavily in technologies that cut electricity consumption, because efficiency will matter just as much as new supply.
That’s where I’ve been focusing my attention: on companies positioned to be part of the solution to this electricity crunch. My search led me to one that has quietly built its business around making buildings more self-reliant and efficient. Its systems are already running in hospitals, universities, and apartment complexes — cutting costs, easing strain on the grid, and keeping heating, cooling, and power flowing when it matters most. In a world where electricity is becoming the new oil, I believe this company could play a much bigger role than most people expect.
Heating, Cooling, and a Smarter Way Forward
When you look at where electricity actually gets used, a huge share comes down to two things: heating and cooling. Every building needs them. Boilers keep hospitals, schools, and apartments warm. Chillers keep data centers, offices, and factories cool. Together, they’re some of the biggest drivers of electricity demand — and some of the biggest stress points for the grid.
And, the way we bring electricity to buildings today is clumsy. Power plants burn natural gas to make electricity, but in the process, enormous amounts of heat are produced and simply released into the air. Then that electricity travels miles before it finally reaches a building, where more energy is burned again by boilers and chillers.
But there’s a smarter way. Instead of burning natural gas at a faraway power plant and wasting half the energy as heat, we can pipe that gas directly to the building. There, it can be used in a small on-site power system called CHP, short for Combined Heat and Power. A CHP unit makes electricity for the building, but instead of letting the leftover heat go to waste, it captures it and puts it to work — providing hot water, space heating, or even cooling. When you pair a CHP system with a natural-gas-powered chiller, the building can cover its own electricity, heating, and cooling needs, all while relying much less on the grid.
And this is exactly where the company I’ve been studying comes in. Tecogen Inc. builds these systems — cogeneration units that generate electricity and heat on-site, plus natural-gas-powered chillers that cut down the need for grid electricity. Together, they give buildings a smarter, more resilient way forward.
Tecogen’s Solutions: A Perfect Fit for the Energy Crunch
So what exactly does Tecogen do? In a nutshell, they make systems that let buildings become their own mini power plants. They have two main product lines that work hand-in-hand.
First, their cogeneration (CHP) systems. These are basically small, on-site power plants that run on natural gas. They generate electricity right where it’s needed and capture the leftover heat for things like heating water or warming the building. Instead of wasting that heat at a faraway plant, the building uses it on the spot.
Then there are their natural-gas-powered chillers, which handle cooling without drawing heavily on the electric grid. These chillers are like building-scale air conditioners that use natural gas engines instead of electricity. Pair them with a CHP system, and a building can generate its own power, use the waste heat, and keep itself cool — all while easing the load on the grid.
In other words, Tecogen’s technology is perfectly built for the energy crunch we see coming. It’s a practical, ready-now solution: it makes buildings more self-sufficient, reduces their dependence on a stressed grid, and helps them stay resilient when demand spikes. In a future where electricity is the new bottleneck, that kind of independence is going to be a game-changer.
Why Tecogen Could Be a Smart Investment
As we look at the big picture, Tecogen sits right in the sweet spot of a growing need for energy efficiency and self-reliance. The market tailwinds are clear: as electricity demand surges and the grid gets more fragile, solutions like Tecogen’s become more essential.
What makes this even more compelling is their new global partnership with Vertiv Holdings (NYSE:VRT), announced in March 2025. Vertiv is a $10+ billion company and one of the biggest names in critical digital infrastructure, with deep ties to data centers around the world. Through this deal, Vertiv will now offer Tecogen’s natural-gas-powered chiller technology to data centers everywhere — a sector under extreme strain as AI drives up both power use and cooling needs.
This isn’t just a distribution boost; it’s a credibility boost. Vertiv has built its business on mission-critical systems that data centers trust to run 24/7, and by adding Tecogen’s chillers to its portfolio, Vertiv is signaling that this technology is battle-tested and ready for the big stage. Investors clearly took notice — the stock has rocketed from under $2 to over $8 year-to-date.
Tecogen’s systems have already proven themselves over 40 years in hospitals and industrial sites, but now, with Vertiv’s global sales reach and integration expertise, the company is positioned to scale rapidly into one of the most important growth markets of the decade: AI-driven data centers.
For investors, this partnership could be transformative. It gives Tecogen instant access to a global customer base it couldn’t have reached alone, and it ties their growth story directly to one of the biggest megatrends unfolding today — the race to build and cool the data centers powering artificial intelligence.
Of course, Tecogen remains a small-cap stock with the risks that come along with it. But with strong industry tailwinds, a world-class partner in Vertiv, and a technology suite that directly addresses one of the most urgent infrastructure bottlenecks, the opportunity looks hard to ignore.
Before getting carried away with the potential, it’s worth looking under the hood. Let’s take a closer look at Tecogen’s financials to see how the business is actually running today.
