Cogeneration
MTM Energia works starting
from a simple premise:
the energy you don't waste
doesn't need to be produced.
MTM Energia works on energy efficiency and cogeneration starting from a simple premise: the energy you don’t waste doesn’t need to be produced.
Every time we burn fuel to generate electricity – in a power plant, an industrial engine, any kind of system – a large share of the energy in that fuel is lost as heat. In conventional systems, this share is around 35-40% of the total. It’s waste that happens right now, every day, in thousands of plants across Europe.
Cogeneration recovers that heat, uses it, and turns it into something useful: hot water, steam, chilled water in trigeneration systems. The result is overall efficiency that can exceed 90%, compared to 40-50% in separate systems. Across most of Europe, cogeneration is still underused, not because it doesn’t work, but because it isn’t known, isn’t understood, and isn’t part of the way companies think about their energy needs.
Knowing the technology exists isn’t enough. In Italy, it took twenty years to bring cogeneration to where it is today, not because plants or qualified engineers were lacking. What was lacking was the culture: the habit of thinking about energy as a resource to be designed, not just a bill to be paid.
The distinction has very concrete consequences. A company that treats energy as a fixed cost passively accepts whatever the market dictates, the prices, the fluctuations, the dependence on the grid. A company that chooses to produce part of its own energy, recover waste heat, and integrate complementary technologies puts itself in a different position. It stops being at the mercy of the problem.
This is the choice MTM Energia made: efficiency first, before anything else.
What concretely changes: less CO2, lower consumption, less grid dependence
Producing electricity and heat in a single process, rather than separately, reduces primary energy consumption. Less fuel burned to achieve the same result or a better one. The direct consequence is a reduction in CO2 emissions that doesn’t depend on incentives to exist: it’s structural, built into the way the plant operates.
The numbers vary from installation to installation, but the scale is significant. A well-sized cogeneration plant can cut CO2 emissions by several hundred tonnes per year compared to conventional systems. In trigeneration – where heat is joined by chilled water production through absorption chillers – efficiency rises further, and the benefits extend to industrial processes that would otherwise require separate cooling systems with their own considerable energy draw.
There’s another equally concrete effect: reduced dependence on the electricity grid. A company that covers a meaningful share of its energy needs through self-production is less exposed to price swings, less vulnerable to supply disruptions, better positioned to plan its energy costs over time. It’s a tangible form of autonomy that shifts the relationship with energy from passive to active.
The benefit for the company and the benefit for the environment, in this case, are the same thing.
For a long time, dependence on fossil fuels was treated as a given, a structural constraint to manage, not a variable to act on. Then came the years when gas prices tripled in a matter of months, supply chains became the subject of geopolitical negotiations, and the word “procurement” stopped being a technical term and became a concrete problem on the balance sheets of thousands of companies.
Energy markets are exposed to dynamics – political, geographical, speculative – that no industrial company can control from within. The only available lever is reducing exposure.
Through cogeneration, a company that produces a significant share of its electricity and heat on-site buys less from the grid, purchases less on the open market, and cushions the impact of price volatility on its operating costs. When the plant runs on biogas or biomethane – fuels produced locally from organic waste – the degree of autonomy increases further, and dependence on international markets is reduced in a structural way.
In markets where cogeneration is still underdeveloped, this is a competitive advantage waiting to be taken.
Everything we’ve written here – efficiency, energy autonomy, emissions reduction – can be measured. There are numbers, percentages, tonnes of CO2. Industrial decisions are made that way, on the basis of numbers.
Behind every plant we install, though, there’s something numbers don’t fully capture. There’s the conviction that the choices we make today about how we produce and consume energy don’t only affect this year’s balance sheet. They shape the kind of world we’re building, slowly, one plant at a time.
We’re a company that designs and installs plants, has a team of engineers, handles maintenance, and picks up the phone when something goes wrong. We chose to do this in a sector where doing your job well and doing something useful for the world are the same thing.
“Your child deserves a better world: choose cogeneration.” We mean it as the reason why, every morning, this work is worth doing.
