ESCO – Energy_Service_COmpany

Z GROUP provides Energy Services through the ESCO Funding Method. Z GROUP undertakes the study and application of energy interventions to customers / users who own or operate facilities such as buildings, industries, factories, etc.

The concept of ESCO lies in the innovative way of paying off the implementation of energy interventions. The interventions are funded by the company and the repayment is made using the following method: The ESCO’s remuneration is inextricably linked to the energy effect / benefit achieved on the customer’s facilities through the Energy Saving Interventions, which funded and implemented by ESCO.

The ESCO is paid for its services from the amount that comes from the energy benefits of the above interventions (€ of energy saving), for the duration agreed in the original study.

The calculation of the energy benefit (and therefore economic benefit) comes from the measurement provided by the installed Real Time Monitoring system, in each sub-part of the infrastructure where an energy upgrade was implemented.

Z GROUP can finance itself or undertake the settlement to finance an energy project, with a certain level of energy savings and a financial result agreed in advance. The above are recorded in the Energy Efficiency Convention, which governs the whole investment.

Z GROUP after the completion of the project, can have a continuous controlling role in both the counting and the confirmation of the energy saved figures throughout the duration of the contract. The equipment of the interventions, throughout the duration of the Contract, belongs to the ESCO. Upon completion of the Contract, the project is delivered to the client and passes into his possession.
