Family C
On-site Generation
Solutions
Solar PV generation and gas-engine cogeneration, both as distributed generation. Sized on your measured load profile, not on your annual consumption divided by twelve.
The problem
The most common mistake in an industrial solar project is sizing it against annual consumption. That produces a big number and an attractive proposal, and it also produces a system that generates at midday while the plant's billable peak happens at seven in the evening.
The result is a bill that drops less than promised and a demand charge that did not move. It is not a panel problem: it is the problem of designing without measuring.
Cogeneration solves something else. If your plant already burns fuel to produce heat continuously, it is throwing away 60 to 70 percent of that fuel's primary energy. Recovering that heat and generating electricity with the same fuel is the only case in which producing your own energy is more efficient than buying it.
The lines in this family
Solar lowers the cost of daytime energy. Cogeneration makes use of a fuel you are already buying. They do not compete: the choice depends on your plant's thermal profile.
Commercial and industrial systems under distributed generation, sized on measurements and with the real load curve on the table.

SEE THE LINE →Signs it applies
Roof, parking lot or ground. The area sets the project's ceiling; orientation and shading define what it will actually produce.
If your peak is at night or in the early morning, solar alone will not touch it. That fact decides whether the project needs storage to make sense.
That is the practical threshold for cogeneration. Without continuous thermal demand there is no heat to recover and the gas engine becomes an expensive generator.
Process hot water, steam, or chilled water through an absorption chiller. The recovery scheme and much of the payback depend on it.
With your bill and a site visit we measure what is needed. And if the curve says solar covers 20% and not the 60% you were promised, we tell you with the chart on the table.
How we work
Measured load profile, area, orientation and —when applicable— the heat balance of your process. Nothing is sized on annual consumption.
Engineering, supply, structure, electromechanical works, integration and commissioning. With baseline metering before energizing.
Interconnection under distributed generation. Solar under exempt generation below 0.7 MW; cogeneration under the distributed generation scheme that applies.
Monitoring, generation reporting and a GTO Vigía contract. A system without O&M loses production silently, and the loss adds up all year.
When it is not for you
If your plant has no continuous thermal demand, cogeneration is not for you. Without a boiler running many hours a year there is no useful heat to recover, and without that a gas engine is just expensive electricity.
If your power factor is below 0.97 or you have high harmonic distortion, correcting that costs a fraction of a solar project and pays back faster. Correct first, generate later.
If your roof has less than five years of service life left, the system will outlast the roof sheeting. That can be solved, but it has to be costed before signing, not after.
And if your interest is in utility scale or in permitted self-supply above 0.7 MW, that project is also done here: it is developed by GIS Power, part of the same group, which currently evaluates projects above ten megawatts. We do the assessment and the introduction, and we stay at the table.
