The cost of installing and launching solar and wind energy facilities, as well as storage systems, exceeds levels presumed by RAE, the Regulatory Authority for Energy, RES agencies and investors have pointed out in public consultation staged by the authority on the cost of new entry for all electricity generation technologies.

RES equipment costs have not only failed to stabilize in recent times, but, on the contrary, struck an upward trajectory, RES officials highlighted.

Some public consultation participants pointed out that RAE’s figures only factor in equipment supply and construction costs without taking into account the connection costs entailed.

SEF, the Hellenic Association of Photovoltaic Companies, rejected RAE’s capital expenditure estimate for domestic roof-mounted solar panel installations, presumed to be €550,000/MW, noting this figure is extremely low and does not reflect actual market conditions.

The association also noted that RAE’s €400,000/MW CAPEX estimate for commercial PVs is also too low, contending this cost ranges between €500,000-€550,000/MW.

The capital expenditure figure for offshore wind farms is far greater than RAE’s estimate of 3.1 million euros per MW, contended ELETAEN, the Greek Wind Energy Association.

“Given the lack of relevant experience in Greece, depth of the seas, and the still-undeveloped supply chain, the €3.1m/MW estimate is probably very optimistic,” ELETAEN stated.
