At RTE's request, Symphonics remotely Symphonics operational solar power plants and improves the profitability of the photovoltaic sector
Paris, November 25, 2025
Amid challenging conditions for the French solar industry, Symphonics its role as an approved balancing provider and is helping solar power plant operators explore a new revenue stream: actively participating in the balancing mechanism managed byRTE, which provides additional revenue and enables better optimization of their facilities.
A solar industry under pressure
The French solar industry is going through a critical period. Despite the ambitious targets set out in the French National Low-Carbon Strategy (SNBC), photovoltaic development is slowing down. Rising construction costs, grid saturation, slow connection times and renegotiated feed-in tariffs are weighing heavily on project profitability.
A New Revenue Stream for Solar Power Plants Thanks to Symphonics
The order of September 8, 2025, which now authorizes solar farms to access additional income via the balancing market, opens up a new perspective.
Solar power plants, including those currently in operation, can generate additional revenue through Symphonics, an authorized balancing provider. AtRTE’srequest, Symphonics remotely Symphonics the plant to ensure grid stability.
The producer is then remunerated for the energy not produced during the shutdown.
This system works for all operating power plants, even those with a purchase obligation contract in S21*.
Symphonics new economic life into the solar industry
This is a breath of fresh air for the industry, which can now turn a constraint (i.e. intermittent production) into an economic opportunity.
By integrating into the grid's balancing mechanisms, solar power producers play a key role in the energy mix.
stability of the power system while boosting the profitability of their facilities.
*The S21 decree regulates purchase obligation contracts for photovoltaic installations commissioned since 2022. It applies to power plants with a capacity of ≤ 500 kWp and defines their tariff conditions applicable for 20 years.
“The French solar industry needs to reinvent itself. Symphonics a concrete solution: turning flexibility into a driver of profitability. Thanks to our balancing and aggregation solutions, solar power plants can tap into new sources of revenue while contributing to the stability of the power grid,” says Mathieu Rochard, founder and CEO of Symphonics.
