GREEN CHP intervention with a new system

The client is an agricultural cooperative that processes vegetables and fresh fruit, over three shifts a day for five days a week. The electricity demand is higher during work shifts but is also present at weekends as the system requires cooling energy. Steam is also used, both in the production process and to clean the plant.

Situation prior to intervention
The Cooperative had annual expenditures of € 900,000 a year on electricity € 300,000 a year on gas. The customer also paid negligible maintenance costs for the methane steam generators.

The proposed intervention and post-intervention situation
Following a technical and economic analysis, Whitenergycreated a 800 kWe plant for the production of electricity, steam and hot water with thermal tracking.
The results of the operation are:

- savings on energy costs incurred for the purchase of gas for the production of steam, equal to € 90,000 per year;
- savings on the costs of purchasing electricity from the Network, corresponding to € 210,000 per year.

The investment was made entirely by Whitenergy, which leaves the choice regarding the management and maintenance of the plants to the client. Having no experience in the operation of cogeneration plants and wishing to concentrate its resources on its core business, the client chose to rely on Whitenergy to manage the plant. Whitenergy manages the plant by paying the operation and maintenance and by selling the electricity and heat produced to the Cooperative at an agreed price. This method provides guaranteed savings, allowing the customer to attain a substantial economic advantage. Generated TEEs are shared between the parties.
