A Canadian greenhouse , eNature Greenhouses , has installed two cogeneration plant with a total electrical capacity of 5.4 MW ( 2 engine of 2.7 MW each ) . eNature is a cucumber grower in Carlisle , Ontario that see an opportunity to participate in a CHP Standing Offer Program ( CHPSOP ) . Under this programme , anytime the toll of electrical energy in Ontario is higher than the cost of produce electricity by the CHP plant , the cogeneration plant life will supply electrical energy into the Ontario grid . Under the CHPSOP curriculum rule , all electricity create must be exported into the Ontario grid .

Although eNature feeds 100 % of the electrical energy to the local grid , thermal vigour regain from the CHP plant will be utilized in the nursery . Should there not be any demand for heat in the glasshouse , while the electricity price in the grid is high enough for the plant to run , heat find from the engine is stack away in a big buffer cooler and can then be used at a recent time .

The benefits of the CHP unit are a significant product cost simplification , a higher revenue due to the electricity trade to the grid , and the opening to use the by - product ( heat ) from the cogeneration system , achieving a very high system of rules efficiency .

Energy to heat the greenhouseThe Energy Department produced by these major power plants can have different applications : the electricity can be used for grow lights , worldwide load , and in summation or as an option , can be exported to the grid to create an additional income stream , as in this case ; the farm warmth will be used to heat the glasshouse or exchange into chill water for cool down and dehumidification intention , while the CO2present in exhaust fumes gases be used as a plant food , to promote plant life growth .

Many CHP systems are design to also support the nursery operations during power grid outage , as they are capable of supplying emergency great power to the glasshouse by running isolated from the grid .

The AB - design schoolmaster and maturate light controls impregnable seamless process , also in compounding with other energy sources like Department of Energy storage and solar arrays . The AB greenhouse program and its controls can also produce a microgrid that provide maximum resiliency .

The treatment of discharge into the atmosphere can be managed by check pollutants in guild to reduce the environmental shock , combining attention to the environs with increase competitiveness .
