The term CHP (High-Efficiency Heat-Electricity Cogeneration) means the combined production of electricity and heat from the same fuel, in order to achieve the full exploitation of its energy content. Thermal energy can also be converted into cooling with a trigeneration system (electricity, heating, cooling). Cogeneration/trigeneration systems can be considered integrated energy systems in the sense that they can cover all final energy uses (electricity, hot water, steam, hot air, cold water, air conditioning, cooling of goods, etc.).

CHP co-generation is considered an efficient and sustainable energy solution, as it optimizes the use of fuels and reduces greenhouse gas and pollutant emissions. It is particularly useful for power generation in industrial plants, hotels, hospitals, waste treatment facilities and other applications that require both electricity and heating or cooling.

The application of High-Efficiency Combined Heat and Power (CHP) plants with Natural Gas combustion in greenhouse crops with Hydroponics for the purpose of producing electricity and selling it to the DEDDIE network, as well as exploiting the heat for to operate with zero energy costs a Hydroponics greenhouse is a profitable business opportunity.

The final configured Energy Market price based on Law 4414/2016 on the pricing of renewable energy sources. and S.H.I.T.Y.A., is calculated as follows: Electricity production of S.H.I.T.Y.A. station: 92€ + PT + 15% increase due to use of heat in a greenhouse +20% price increase due to carbon dioxide channeling (CO2) in the greenhouse. The Total Purchase Price Increase is equal to 35% + PT.
