Challenge / Goal
The smart energy and self-sufficient block aims to reduce electric consumption in tertiary buildings through renewable energy, especially photovoltaic. Photovoltaic generation coupled with the use of storage batteries allows optimisation of the relationship between generation and consumption even in low solar production instances.
PV power plants with energy storage are installed, the electricity storage is controlled and managed by an advanced Energy Management System (EMS), which optimizes the battery performance according to pre-established functionalities.
The production and consumption of the systems installed in the buildings is managed “virtually” in order to analyse possible scenarios for the electric grid at island level, particularly in cases of complementary consumption profiles. This is also because according to the new law RD 900/2015 of 9 October 2015, present conditions of electricity self-consumption and feed into the grid which are not economically attractive.
Services offered are electric renewable on-site generation from photovoltaic power plants (1.5 - 6 kW photovoltaic power + Li-ion battery, depending on each community) to cover part of the buildings electricity consumption and optimisation of community lighting consumption by installing LEDs.
