Cyprus experienced a sharp rise in solar energy curtailment, exceeding 65% in the first five months of 2026, mainly due to grid limitations and operational constraints on conventional units. This impacts project viability and renewable deployment.
Cyprus curtailed more than 65% of its potential solar energy output during the first five months of 2026, driven by grid constraints and operational limitations on conventional power plants, according to PV Magazine.
In the first five months of 2026, Cyprus curtailed approximately 162 GWh of solar energy, a volume that exceeds 65% of the country’s estimated solar generation potential for that period. The majority of affected plants are photovoltaic systems, along with 12.5 MW of biogas capacity and 24 MW of wind power connected to the distribution network, as reported by CyprusGrid, an energy analytics platform.
Curtailment rates have increased sharply from around 12% in 2022 to 47% in 2025, with notable surges during spring and autumn. During June to August 2025, curtailment more than quadrupled compared to the same months in 2024, raising concerns about the trend continuing into 2026, which could see record levels exceeding 60%.
Experts attribute the rise primarily to the continued operation of must-run conventional units, which limit renewable energy integration. Additionally, depressed wholesale electricity prices, partly caused by renewable oversupply, have compounded the issue. Cyprus does not compensate renewable investors for curtailed energy, creating revenue challenges for project owners, especially as market conditions deteriorate.
Impacts of High Curtailment on Cyprus Renewable Sector
This surge in curtailment significantly affects the financial viability of renewable projects in Cyprus, particularly for residential PV systems. The lack of compensation and low wholesale prices threaten future investments and the country’s renewable energy targets. The situation highlights the systemic challenges of integrating high levels of renewables into a constrained grid, with potential implications for energy policy and market reforms.

Renewable Expansion and Grid Limitations in Cyprus
Cyprus has seen increasing deployment of residential PV systems, driven by self-consumption incentives and prosumer models. However, grid constraints and operational policies have historically limited renewable integration. Starting in 2025, residential PV curtailment has risen sharply, with the first five months of 2026 recording a record 46,687 MWh of curtailed residential and small-scale solar energy, up from 1,565 MWh in 2025.
The broader context involves ongoing challenges in balancing renewable growth with grid stability, as conventional power plants continue to operate as must-run units, restricting the absorption of renewable energy. The trend reflects a structural mismatch between renewable generation capacity and grid infrastructure capacity.
“A key driver behind Cyprus’ record curtailments is the continued operation of must-run conventional units, which occupy a significant share of grid capacity that could otherwise be used by renewables.”

Uncertainties Around Future Curtailment Trends
It remains unclear whether Cyprus will implement measures to alleviate grid constraints or provide compensation for curtailed energy. The extent to which policy changes, grid upgrades, or storage solutions will mitigate future curtailment levels is still under discussion. The trajectory of wholesale prices and market reforms also influences the potential for project viability improvements.
Next Steps for Cyprus Renewable and Grid Development
Authorities and industry stakeholders are expected to explore grid reinforcement projects, policy adjustments, and incentives for energy storage to reduce curtailment. Monitoring of 2026 data will clarify if curtailment levels stabilize or continue to rise, guiding future investment and regulatory decisions. Further discussions on compensation mechanisms may also shape the sector’s outlook.
Key Questions
Why has Cyprus experienced such high solar curtailment in 2026?
The main reasons include grid constraints, the operation of must-run conventional units, and depressed wholesale prices, which limit renewable energy absorption and project revenues.
Are residential PV systems affected by curtailment in Cyprus?
Yes, residential PV systems have seen a sharp rise in curtailment, reaching a record 46,687 MWh between January and May 2026, impacting small-scale solar owners.
What are the implications for renewable energy projects in Cyprus?
The lack of compensation and ongoing curtailments threaten project viability, potentially slowing future deployment and affecting the country’s renewable targets.
Could grid upgrades or policy changes reduce curtailment?
Potentially, yes. Upgrades to grid infrastructure, storage solutions, and policy reforms could help absorb more renewable energy and reduce curtailment levels.
What is the outlook for Cyprus’s renewable energy sector in 2026?
The sector faces challenges due to high curtailment, but ongoing discussions on infrastructure and market reforms could improve conditions later in the year.
