AleaSoft Energy Forecasting, July 2, 2026. In June 2026, solar photovoltaic energy production reached all-time highs in the main European electricity markets. Wind energy production also broke records for a month of June in France and Portugal. Monthly average prices rose in most markets, driven by higher summer demand and higher CO2 emission prices, despite the fall in TTF gas prices and Brent oil prices compared with May.
Solar photovoltaic and wind energy production
In June 2026, solar photovoltaic energy production rose in the main European electricity markets compared with the same month of the previous year. Spain recorded the highest percentage growth, at 18%. France followed with 17% and Portugal with 16%. Germany increased its production by 5.5%, while Italy recorded the smallest increase, at 0.7%.
Compared with May 2026, solar photovoltaic energy production also grew in all the markets analysed. Spain and Portugal recorded the largest increases, at 18% in both cases. France increased its production by 15% and Italy by 11%, while Germany recorded the smallest increase, at 4.8%.
In June 2026, the main European electricity markets broke their all-time highs for solar photovoltaic energy production. Germany led monthly photovoltaic energy generation, with 11 168 GWh, its highest figure to date. Spain reached 6957 GWh, followed by Italy, with 4428 GWh, and France, with 4384 GWh. Portugal also set a new all-time high, with 823 GWh.
These solar photovoltaic energy production records reflect the year-on-year growth in installed capacity. Between June 2025 and June 2026, the Spanish market added 8689 MW of solar photovoltaic capacity, excluding self-consumption, according to data from Red Eléctrica. Over the same period, the Portuguese market added 739 MW to the system, according to data from REN.

In June 2026, monthly average prices exceeded €100/MWh in five of the main European electricity markets analysed by AleaSoft Energy Forecasting. The Italian market reached €132.50/MWh, the British market €114.94/MWh, the Belgian market €112.13/MWh, the Dutch market €110.08/MWh, and the German market €109.52/MWh. In contrast, the Iberian markets and the French market recorded lower prices, with averages of €69.59/MWh in Spain, €70.25/MWh in Portugal and €66.07/MWh in France. The Nordic market closed the month at €64.78/MWh.
Compared with May 2026, average prices rose in most of the European electricity markets analysed by AleaSoft Energy Forecasting. The largest percentage increases corresponded to the Portuguese and Spanish markets, at 30% and 28%, respectively. France recorded a rise of 27%, Belgium of 22%, the Netherlands of 16% and Germany of 12%, while Italy rose 11%. The exceptions were the Nordic and British markets, with falls of 15% and 4.8%, respectively.
Comparing June average prices with those recorded in the same month of 2025, prices also rose in most of the European electricity markets analysed. The Nordic market recorded the largest percentage increase, at 236%, followed by the Belgian and German markets, with rises of 72% and 71%, respectively. The Dutch and French markets recorded increases of 63% and 62%, the British market 46%, and the Italian market 19%. In contrast, the Iberian markets recorded year-on-year falls, with drops of 4.1% in Spain and 5.3% in Portugal.
As a result of the price increases, the Belgian and Dutch markets reached their highest monthly averages since March 2025. The German, French, Portuguese and Spanish markets recorded their highest prices since February 2026, while the Italian market reached its highest monthly average since April 2026.
The rise in CO2 emission allowance prices compared with May, together with the sharp increase in demand at the start of summer, favoured the rise in prices in most continental electricity markets compared with the previous month. The fall in wind energy production in Italy also contributed to the price increase in that market.
Compared with June 2025, the rise in TTF gas and CO2 prices, together with demand growth in most markets, drove the year-on-year increases in the continental markets of northern and central Europe. The fall in wind energy production in Germany also contributed to the price increase in that market. In the Iberian markets, a higher renewable contribution led to the year-on-year fall in prices.

Brent oil Front-Month futures on the ICE market recorded an average price of $84.43/bbl in June 2026. According to the data analysed by AleaSoft Energy Forecasting, this monthly average was the lowest since March. This figure was 19% lower than in May 2026, when the average stood at $103.71/bbl. However, it exceeded the June 2025 average, which reached $69.80/bbl, by 21%.
During June, progress in diplomatic negotiations between the United States and Iran and the prospect of greater supply in international markets pushed oil prices down. Expectations of a slowdown in global demand also contributed to the fall in the average price compared with the previous month.
Regarding TTF gas Front-Month futures on the ICE market, the average price recorded in June 2026 was €44.94/MWh. According to the data analysed by AleaSoft Energy Forecasting, this price was the lowest since March. This figure was 4.8% lower than in May 2026, when the average stood at €47.23/MWh. Compared with June 2025, whose average price was €36.65/MWh, the increase reached 23%.
The fall in the TTF gas price compared with May 2026 was linked to greater supply availability and the easing of geopolitical tensions in some regions. However, European gas reserve levels remained relatively low for the time of year, which limited the extent of the fall and kept gas prices above the levels seen in June 2025.
Regarding CO2 emission allowance futures on the EEX market for the December 2026 reference contract, the average price reached €79.06/t in June. According to the data analysed by AleaSoft Energy Forecasting, this average was the highest since February. This figure was 3.6% higher than the €76.31/t recorded in May 2026, and exceeded the June 2025 average of €74.94/t by 5.5%.

To achieve a profitable and bankable investment, energy storage projects need to identify the configuration that maximises revenues, anticipate the evolution of arbitrage and balancing service opportunities, assess the impact that growing battery penetration will have on those revenues, and define the optimal sizing of hybrid projects. These issues are especially relevant both in stand-alone systems and in hybrid installations, such as solar photovoltaic or wind plants with batteries.
To address these challenges, AleaSoft Energy Forecasting‘s AleaStorage division services help optimise the revenues, sizing and profitability of storage systems. AleaStorage‘s solutions include long-term revenue estimation reports for different energy storage project configurations, for both hybrid solar photovoltaic systems with batteries and stand-alone installations. The analysis compares different durations and operating modes, and includes revenue forecasts from arbitrage in day-ahead and intraday markets, balancing services and the capacity market.
