First Model of Collective Self-consumption

Primer modelo de autoconsumo comunitario

 

Red Eléctrica with the Megara Energía cooperative and the Town Hall of Castilfrío de la Sierra (Soria), has launched the first local energy community through the pilot scheme “Hacendera solar”, a prototype of rural energy community based on a collective self-consumption, supported by Red Eléctrica, and a participative model involving the town hall and local population to manage the project.

 

(Available only in Spanish)

 

This pilot scheme is aimed at:

  • Outlining the first collective self-consumption model in Castilfrío de la Sierra (Soria).
  • Promoting photovoltaic installations for shared self-consumption with network backup.
  • Promoting investing in low-carbon economies to reduce both emissions and current town hall expenses.
  • Defining the complementarity of the energy demands of the different buildings and equipment owned and/or managed by a town hall.

 

The “Hacendera solar” in Castilfrío de la Sierra has two photovoltaic solar plants of 7.36 and 5.5 kWp for self-consumption that have been installed on the roofs of the municipal buildings. These installations supply electricity to the town hall, the social centre, the doctor’s clinic, a refurbished building and the laundry-room, as well as for pumping water.

 

2020-2021 Results
  • Creation of the governance body of the energy community and approval of the By-laws.
  • 100% self-consumption has been achieved in the water pump and 84% use in the social centre.
  • A slow charging point for electric vehicles has been set up in the social centre.
  • Coverage of 60% of the annual electricity demand of the town hall.
  • Reduction of its carbon footprint by 6.98 t CO2 eq. per year.
  • Creation of a model that can be extrapolated to the rest of the region’s towns.
