The Regional Government of Castilla y León has appointed EREN, the regional Energy Agency, to manage some European Regional Development Fund (ERDF) funds for the period 2021 – 2027. €20,5 million have thus been allocated to carry out PV solar installations in Regional Administration buildings (60% co-financing).
Using their database, EREN analysed the electricity consumption and contracted access rates of all these administrative buildings, discarding those with a consumption of less than 65.000 kWh/year. The resulting list included 349 buildings.
The average annual PV production of these buildings is 1.250 net hours. An average ratio of 1,25 MWp/MW is considered. Regarding self-consumption, the rate varies between 10% and 65% depending on the building type (hospitals, residences, administrative or educational buildings).
Based on this analysis, EREN developed a software for pre-dimensioning the power of the PV production installation for self-consumption, resulting in a maximum power to be installed of 22,24 MWp, represents a total investment of €30 million.
Priority was given to investments in public hospitals, estimated at €8,25 million, which represent a power of 8,62 MWp. For the rest, EREN considered that 56,3% of the potential investments will be executed, representing €12,25 million of investment in residences, administrative and educational buildings, and corresponding to a power of 8,65 MWp. With these projections, the total planned execution is €20,5 million and 17,27 MWp.
The following installations have been executed to date:
• Río Hortega University Hospital in Valladolid: 1.146,6 kWp and an investment of €975.415.
• Hospital Clínico Universitario in Salamanca: 506 kWp and an investment of €485,431.
The 397,1 kWp installation at the Hospital Clínico Universitario in Valladolid, with an investment of €377.726, is currently in the bidding period.
In addition, execution projects are being drafted for the installations at the Monte San Isidro Hospital (183,3 kWp) and Santa Isabel Hospital (117,97 kWp) and at the Eras de Renueva Health Centre (116,48 kWp).
