The PEGASUS Interreg MED project (Promoting Effective Generation and Sustainable USes of electricity) aims to give evidence of the feasibility of microgrids acting on technical or administrative obstacles which are hindering the use of microgrids in disadvantaged areas; a tested business model will show advantages of smart interconnection and facilitate the adoption of necessary acts to define an ENABLING environment. The innovative approach of PEGASUS focused on experimenting a simulation of functioning of microgrids in 7 pilot areas jointly; solutions will be based on concrete situation with real data.
The Potenza pilot site is aimed at demonstrating the achievable advantages (primary energy, peak shaving, reduction of energy bills) by the Municipality in two different sites: a swimming pool, where a 165 kW CHP is able to provide about 95 % and 85 % of the required thermal energy and electricity, respectively, and also to feed, through the existing distribution network, about 70 % of the electricity consumed by an electric escalator, having an installed power of 192 kW and being used to transport people from the outskirts to the city centre.
The existing boilers in Montereale swimming pool will be partially substituted by a Combined Heat and Power system (CHP) driven by the heat demand of the swimming pool. The related generated electricity is used to meet the electric demand of Montereale swimming pool; the surplus is fed into the local distribution network in order to be used by the Santa Lucia escalator, by virtue of the regulatory solution called 'Scambio Altrove'.
The assessment of the monitoring carried out on the acquired data in the period from November 2017 until May 2018 identifies in a CHP system, 120 kW in thermal power and 65 kW in electric power, the most profitable solution. In addition to the intrinsic energy benefits of the CHP system it has been evaluated 25 MWh/year of reduced losses on the electrical network related to the pilot.
