Substation 450 kW. Each building has a substation that supplies hot water to all homes. Individual heat unit. Each house has a heat unit with instantaneous production of domestic hot water with a meter that allows monitoring the consumption of all users of the heat network.
FUNCTIONING OF THE SYSTEM People who move to the new neighbourhood of Txomin Enea will do so to eco-efficient homes, designed to respect the environment by reducing energy consumption. These residents also have access to their energy consumption in real time, since the data is updated every 5 minutes, and thanks to this information they will be able to improve their consumption patterns. For the consumers, part of the price is fixed, and another part is variable: the fixed price is 240 euros per year per service point plus a variable price according to the actual amount of consumed thermal energy. The variable part is divided into two: the price of the energy consumed in each residence (0.08050 euros/kWh) and the energy that is lost in the distribution grid (0.04901 euros/kWh), which shall be apportioned among all the consumers. The price for the energy not consumed is calculated to cover only the costs of the primary energy, encouraging all actors involved in the heat network to minimise losses. The prices will be reviewed once a year based on a series of variables related to the costs of the system, but with the guarantee from Fomento de San Sebastián that the end user price will never exceed the CPI (Consumer Price Index) year- on-year.
It is estimated that the economic savings for each of the residences will be approximately between the 10 % and 15 % of the price of a traditional centralized system and even more with an individual system. In addition, CO2 emissions will be reduced by more than 80 %.
- 2x1,400 kW biomass, 2x2,300 kW gas. - 1,390 residences with individual heat units. - 14 double substations for the buildings. - 10 %-15 % economic savings or the end user. - 80 % lower emissions.
