ALENS offers consultancy services to assist the customer in finding the necessary documentation and in submitting requests for qualification as High Efficiency Cogeneration (HEC) in accordance with the procedures laid down in the Decree of the Ministry of Economic Development of 5 September 2011. 

Cogeneration is the combined production, in a single process, of electric energy – or mechanical energy- and heat. A cogeneration unit is defined as high efficiency if the resulting value of primary energy savings (PES) is at least 10% or, in the case of micro-cogeneration units (<50 kwe) or small cogeneration units (<1 Mwe), if it assumes any positive value. 

The GSE provides annual recognition of the final HEC operation and, for cogeneration units that require it, the subsequent recognition of the number of white certificates to which they are entitled. The GSE also examines requests for preliminary assessment (budget) for units not yet in operation, aimed at subsequent access to white certificates. 

Final applications must be submitted each year by the 31st March of the year following the production to which they relate. 

However, requests for preliminary assessment may be submitted at any time of the year

The great experience gained in the presentation of these requests allows Alens to have a wide range of positive feedback concerning previous problems, which allows a simple and safe approach to the qualification, also aimed at obtaining white certificates. 

Autoproduction and SEU

Autoproduction form renewable sources and from cogeneration is one of the modality that allows energy supply cost reduction and also the reduction of the client’s carbon footprint.

How we can help:

  • support the Customer in the best chioce of on-site and off-site autoproduction configuration;
  • we study the optimal size of the plant that maximizes the yield, the contractual formula, the exploitation of the plant and the sustainability from the energy and economic point of view;
  • we evaluate all plant interferences and any impacts from energy efficiency reductions  and CO2 impact; 
  • we analyse the short, medium and long term energy and market scenarios of the chosen configuration or contract form
  • we assist in the selection and drafting of the purchase, supply, rental, and EPC contracts;
  • we carry out the assessment to verify the fulfillment of the market, tax and environmental regulations of the chosen solution or the configuration of the plant;
  • management of administrative and tax practices related to excise duties electricity and natural gas for producers, consumers, sellers and wholesalers;
  • management of excise duty exemption on practices of electricity, natural gas and diesel. 


PPA contracts (power purchase agreement) and energy communities are two methods of approach to the use of energy produced from renewable sources tending to favour the installation of RES plants exceeding the physical limits of self-production. 

How we can help:

  • we assist your choice and writing of EPC and PPA contracts;
  • study, configuration and energy management of energy communities (collective self-consumption or renewable energy community)  and SDC;
  • we analyze the energy and market scenarios in short – medium – long term of the configuration or the contractual chosen form;
  • we carry out the assessment to verify the fulfillment of the market, environment, and fiscal  regulations or the configuration of the existing plant.
