Italy’s rapid expansion of solar power risks higher costs and project delays unless key bottlenecks in permitting and grid infrastructure are resolved, according to analysis from GlobalData.
The company warns that while Italy is undergoing a major clean energy transformation, the pace and efficiency of reforms in grid access, permitting, and system flexibility will determine whether the transition remains affordable and reliable as electricity demand continues to rise.
In its latest report, “Italy Power Market Trends and Analysis by Capacity, Generation, Transmission, Distribution, Regulations, Key Players and Forecast to 2035”, GlobalData highlights that solar photovoltaic (PV) has become the fastest-growing generation segment in Italy.
This expansion is being driven by auctions, policy incentives, and strong solar resources. At the same time, hybrid renewable projects combining solar or wind with storage are gaining momentum as a way to manage grid constraints and reduce curtailment risk.
However, GlobalData stresses that despite this progress, structural challenges in permitting and grid connection continue to limit deployment speed.
The report also points to a significant increase in electricity demand over the coming years. After a slight decline in the early 2020s, Italy’s consumption is expected to rise from around 292.2 TWh in 2025 to 311.1 TWh by 2030.
This growth will be driven by electric vehicles, heat pump adoption, hotter summer temperatures, and expanding industrial and digital energy needs. Southern Italy and island regions are identified as areas likely to face the greatest stress on grid infrastructure and connection capacity.
While renewable energy continues to expand, natural gas still plays an important role in providing backup and system flexibility. However, GlobalData notes that its influence is gradually being reduced due to decarbonisation policies and the increasing penetration of renewables in the electricity mix.
The report highlights that Italy’s National Energy and Climate Plan, along with mechanisms such as the FER X auction scheme and strengthened capacity markets, are helping to improve investment signals for renewable energy projects.
At the same time, permitting reforms and grid planning improvements are intended to reduce long-standing delays in project development.
However, GlobalData analyst Attaurrahman Ojindaram Saibasan warns that regional zoning restrictions, heritage protection rules, and overlapping environmental assessments continue to slow deployment in many high-potential areas.
According to Saibasan, hybrid renewable projects—combining solar with storage or wind with storage—are becoming increasingly attractive because they help reduce grid congestion and curtailment risks.
However, he stresses that without faster permitting, clearer grid access rules, and greater investment in storage, Italy risks delays, higher costs, and reliability challenges during peak demand periods.
Looking ahead, GlobalData concludes that Italy offers strong opportunities across solar PV, offshore wind, storage, and grid modernisation. However, the success of the transition will depend on the ability of developers and policymakers to overcome regulatory uncertainty and infrastructure bottlenecks.
Saibasan adds that securing long-term contracts, navigating policy complexity, and anticipating regulatory constraints will be essential for investors operating in the Italian power market over the coming decade.
