Cyprus solar rules face scrutiny as photovoltaics supply a quarter of daily power demand
Photovoltaics now cover about a quarter of Cyprus’s daily electricity demand, but most generation does not enter the market directly. Regulatory pricing, limits on bilateral contracts and the concentration of curtailment among large solar parks determine how costs and benefits are distributed.
Small systems dominate solar generation
Photovoltaic generation now supplies about one quarter of Cyprus’s daily electricity demand, according to sbctv.gr, but much of that output never passes through the electricity market. The central issue is therefore not only how much solar power the country produces, but which installations receive payment, how their electricity is priced and who bears the cost of balancing the grid.
Official Distribution System Operator data cited by the publication divide distributed photovoltaic generation into three main categories. More than 102,000 small systems on homes and businesses account for most of the solar profile: 99,854 operate under net metering and 2,343 under net billing. Only 254 large-scale installations participate in the market, leaving the commercial segment much smaller in number than rooftop generation.
The composition changes with demand. On a low-demand day, large solar parks supply 3.9% of total electricity requirements, while their share rises to 9.8% on a high-demand day. Uncontrolled residential systems move in the opposite direction, from 8.8% to 3.7%. Their production remains relatively stable at 972 MWh and 876 MWh respectively, indicating that the change in market share reflects total demand rather than substantial curtailment of household systems.
Large parks carry the curtailment risk
When electricity demand is low and sunshine is strong, system management places almost all of the curtailment burden on large photovoltaic parks to preserve grid balance, sbctv.gr reported. Smaller and more local producers face less exposure to output restrictions. Large plants consequently absorb an operating risk that is not directly visible to consumers on their electricity bills.
Most photovoltaic production is also effectively invisible to market price formation. Self-consumed or distributed solar reduces the amount of electricity that conventional generating units must supply, especially during sunny hours, but it does not itself set a market price. This distinction complicates claims that revising solar power sales agreements could deliver a broad and immediate reduction in consumer bills.
Regulated pricing limits commercial flexibility
Renewable electricity purchased under national support schemes is priced by regulation at €0.11/kWh. The level is based on the Cyprus Energy Regulatory Authority’s fuel adjustment methodology and Regulatory Decision 112/2023. When the avoided cost of Electricity Authority of Cyprus generation exceeds that threshold, the price is fixed at the average purchase price recorded during 2013-2022.
The regulatory framework also restricts contracting. Under CERA Regulatory Decision 01/2021, KDP 359/2021, paragraph 7.74, EAC Supply is expressly prohibited from signing bilateral wholesale contracts. The sole exception is electricity from renewable plants covered by national schemes, purchased at exactly €0.11/kWh. This leaves limited room for negotiated prices or more flexible commercial arrangements.
Proposals to revise solar agreements can therefore affect only a small, visible part of total photovoltaic production. Any wider effect on bills will depend on how curtailment risk is allocated, how the balance between rooftop systems and large parks develops, and whether rules that currently fix the solar purchase price are changed. More transparent data on the number of agreements, the production volumes they cover and the entities managing them would be necessary to assess who gains from the existing system and whether lower solar generation costs reach households and businesses.
