Efficient battery management will determine the profitability of renewable energy projects
Energy storage development is now the cornerstone of renewable energy development. After the blackout of April 28 in the Iberian Peninsula, it has become clear that the stability and reliability of the electricity grid in the future depend to a large extent on the deployment of batteries. If batteries are managed optimally, they can generate good profitability over their lifetime. In this five-year period, which began in January, photovoltaic energy will be installed hybridised with batteries to achieve better IRR and obtain financing.

Photovoltaic energy records and more wind energy help to contain European electricity market prices in the fourth week of May
During the fourth week of May, prices fell in most major European electricity markets, while in others they remained stable, with slight increases. Increased wind energy production and all-time records for solar photovoltaic energy generation in France and Portugal, together with the maximum for a day in May in Italy, helped to contain prices. In addition, electricity demand fell in most markets. In contrast, gas prices rose compared to the previous week.

Renewable energy and lower demand moderate European electricity market prices despite rising gas and CO2 prices in the third week of May
In the third week of May, the main European electricity markets showed mixed evolution, although in most of them weekly prices were lower than the previous week. Despite the increase in gas and CO2 prices, higher renewable energy generation and lower demand allowed prices to be contained and lowered in some cases. The Portuguese market once again broke its historical record for daily photovoltaic energy production and the German and Italian markets reached the highest production with this technology for a day in May.

Is the inertia of synchronous generators of thermal power plants necessary?
The transition to a 100% renewable electricity system also involves rethinking the technical foundations that have underpinned its stability for decades. One of these pillars is the system inertia, traditionally provided by synchronous generators. In a system dominated by renewable technologies, this inertia disappears, posing a challenge for maintaining grid stability. In this new context, technologies such as batteries with grid-forming inverters emerge as a solution to provide virtual inertia and reinforce the resilience of the electricity system.

European electricity market prices rose in the second week of May, but registered negative values during the weekend
In the second week of May, prices in most major European electricity markets increased compared to the previous week, except in Spain and France. Over the weekend several markets registered negative hourly prices, with an all-time record in Spain, as well as the lowest prices since at least 2023 in other markets. In France and Belgium there were negative daily prices, with values not seen since 2020 in France. Portugal registered an all-time record for photovoltaic energy production, while France reached the highest wind energy production for a day in May in the last four years. Electricity demand, as well as gas and CO2 prices, rose and Brent futures registered the lowest value since February 2021.

Storage: the key to decarbonisation and energy independence
Energy storage is no longer a promise of the future but a strategic pillar of the present. The 2025 edition of Intersolar Europe has confirmed that batteries both in stand-alone and hybrid systems are positioned as the key structural element for integrating renewable energies, ensuring security of supply and accelerating energy independence.

The future of the European electricity system without polluting energy sources
The European electricity system is moving towards a fully decarbonised model, where energy storage, grid digitalisation, active demand management, more robust interconnections and a diversified renewable energy mix will be key pillars. Achieving this will require a profound technological, regulatory and economic transformation, as well as the active involvement of all stakeholders in the sector.

Rising renewable energy production and falling gas prices push European electricity market prices down in the first week of May
In the week of April 28, prices in the main European electricity markets decreased compared to the previous week. Falling demand and gas prices, as well as increased renewable energy production, supported these declines. Photovoltaic energy set all-time generation records in France and Italy, as well as the highest production for a day in April in Germany. Wind energy production increased in the continent’s major markets. TTF gas futures reached the lowest settlement price since July 2024 and Brent futures since March 2021.
