📋 Tender Overview
From July 17, 2026, the Ministry of the Economy is launching a sixth call for tenders for companies to support investments in photovoltaic installations and storage solutions (PV6). This call for tenders is aimed at companies to support them in the construction of photovoltaic power plants with a power of between 30 kWp and 3,000 kWp, with particular attention paid to storage solutions. The fifth call for tenders (PV5), closed in April 2026, made it possible to support 16 projects out of the 21 requests received for a total amount of aid of 1,113,264.87 euros, representing an installed capacity of 1,934.02 MWp. Open to all companies, this call for tenders was particularly aimed at small installations, between 30 kWp and 200 kWp. This 6th call for tenders is a continuation of the positive results of the 5th call. The Minister of Economy, SMEs, Energy and Tourism, Lex Delles, comments: This new call for tenders is a continuation of our efforts to promote renewable energies and support the energy transition. Beyond the installation of new capacities, this call for tenders contributes to strengthening the resilience of the electricity system, in particular by supporting projects integrating storage batteries, a key technology for optimizing the flexibility and efficiency of the network. The encouraging results of the 5th call for tenders show the commitment of companies, including SMEs, to this approach. In addition to the installation of new production capacities, PV6 encourages companies to maximize the recovery of their electricity, particularly through self-consumption. Projects integrating a storage solution benefit from increased support, highlighting their strategic role in the energy transition and the need for additional investments. PV6 has an overall budget of 10 million euros, divided into three lots: Lot 1 > 30 kWp and <= 3,000 kWp (roofs of buildings; ZAE land) - Sublot 1a: without batteries - Sublot 1b: with batteries Lot 2 > 30 kWp and <= 2,000 kWp Innovative (on a building: roofs with light modules, modules in facade) - Sublot 1a: without batteries - Sublot 1b: with batteries Lot 3 > 30 kWp and <= 2,000 kWp (shades) (on a building: roofs with light modules, modules on the facade) - Sublot 1a: without batteries - Sublot 1b: with batteries Modalities and timetable The aid will be awarded according to the principle of competitive bidding, based on the criteria defined in the specifications.
