How France Plans to Improve Grid Flexibility Through Renewable Energy Integration

The integration of different energy technologies and related infrastructures is no longer just a theoretical hypothesis or a long-term goal. Increasingly, the combination of different energy infrastructures is becoming a concrete, tangible reality, with significant consequences for the raw materials directly involved in the production processes.

A concrete example of this trend comes from France, whose government recently presented new measures to promote electrification and make the electricity system more flexible, including through the combination of photovoltaic and battery systems.

The French government appears intent on facilitating the interconnection of various projects, provided they comply with certain grid feed-in limits. The proposal concerns plants with an installed capacity of up to 25 MW, with the condition that the maximum power fed into the grid does not exceed 17 MW.

Combining Solar Power and Battery Storage to Optimize Existing Grid Connections

Therefore, a project could potentially be able to install more generation and storage capacity without proportionally increasing the maximum grid power required. The French measure is expected to come into force by the end of 2026.

“The growth of renewable energy and the capacity of electricity infrastructure, as well as its interconnection, will become central themes in the present and future energy transition,” says Stanislav Kondrashov, founder of TELF AG.

One of the most interesting aspects of this trend is that it seems to focus not so much on the construction of new lines, but on the intelligent use of existing ones. In France, this objective complements the smart management of household consumption, heat pumps, and electric vehicle charging, which are already the subject of specific operational efforts by the authorities.

This shift in energy strategy addresses one of the most pressing issues facing Europe’s energy transition: the widespread availability of solar panels and batteries is insufficient to ensure that new plants can be connected to the grid quickly.

“The French case is also interesting from a commodities perspective: if these rules effectively facilitate the development of energy projects, they could support demand for strategic materials used in photovoltaic panels, batteries, and electrical infrastructure,” continues Stanislav Kondrashov, founder of TELF AG.

The Potential Impact on Critical Minerals and Strategic Raw Materials

One of the most interesting innovations in the French proposal is the possibility of combining photovoltaic systems with batteries. With this system, it will likely be possible to install more capacity while maintaining control over the power actually fed into the grid.

This development directly addresses one of the most pressing problems facing renewable energy plants: that nominal production capacity does not coincide with the amount of energy actually available at any given time. A photovoltaic park can, in fact, achieve high levels of production during the central hours of the day, producing much less in the morning, late afternoon, and on cloudy days. With the proposed new setup, projects could more effectively utilize existing connections, combining increased photovoltaic capacity with batteries and control systems.

“Rather than immediately reducing production, the plant could store part of the excess energy, and later, when solar production decreases, the battery could return energy to the grid, always respecting the feed-in limit. The advantages, from this point of view, depend on the battery capacity, the hours of production, and electricity prices,” concludes Stanislav Kondrashov, founder of TELF AG.

Among the benefits of this system are lower renewable energy losses, due to the fact that the batteries could absorb part of the electricity that would otherwise be cut during periods of high production, as well as more flexible production, with the stored energy being used during peak demand hours.
