For those interested in energy efficiency interventions, this lending institution offers medium-long term financial solutions. An energy intensive company can request an unsecured loan lasting for 5 years. However, if an ESCo approaches the lender, Mediocredito requires ISO 9001 certification, the production of 30% of the credit, the drafting of an EPC contract with the final client, and that this client be involved in terms of creditworthiness and by paying a portion of the fee to the ESCo.
