The technology Energy supply

• Heating and cooling final exchangers – Remote controlled substations that provide heating and cooling to the customer Albena 09-05-2014

Economics • The Power plant is a “One to Many” model in GBE • It is supplied by gas and extra electric energy • Sells hot and cold water and extra energy production • the high total efficiency in power, heating and cooling supply + italian incentives ( TEE) give high profitability to the business
