Gas cogeneration

The sharp increase in energy costs have negatively impacted the profitability of companies with high electricity and heat consumption, such as hotels, hospitals, sports centres and production industries.

The installation of a high efficiency cogeneration system allows the joint and simultaneous production of electricity and heat, improving the efficiency of the fuel (natural gas or biogas).

Simultaneously producing electricity and recovering heat energy, from engine cooling water or oil and from exhaust gases, uses almost all of the energy potential of the fuel.

Enerqos’ proposal

  • Selection and implementation of a 50 kW cogeneration system on the basis of a detailed analysis of the electricity and heat consumption of the customer
  • Financial solution customized to the specific requirements of the customer
    • Financing through Enerqos and a sharing of the savings of electricity and heat consumption, with a maintenance contract for a period of 3 to 5 years
    • Co-investment by Enerqos and the customer and a sharing of savings, with a maintenance contract for a period of 3 to 5 years
    • Customer’s own investment with the option of a maintenance contract
  • Consulting regarding access to all possible incentives available at regional, national and European level

Benefits for the customer

  • Increase in the competiveness of the company through immediate reduction of the costs of electricity and heat consumption
  • Optimization of financial resources through access to different solutions, or qualified assistance in accessing credit, with no initial outlay
  • Technological solution customized to the needs of the client, with installation of the best cogeneration solutions available on the market without contractual ties to suppliers
  • Optimization of the various planning and operational phases with Enerqos’ proven experience of project-management
  • Medium to long term support from trusted and highly qualified partner
  • Improvement in the customer’s ‘green’ image
