The French energy sector is going through a pivotal point at the moment. As the country moves away from nuclear and fossil fuels towards renewables, many problems are arising. The arrival of Covid-19 has also not been helpful for the deployment of renewable energy systems, especially for solar PV. As a result, France has only added 176 MW of solar PV capacity in the first quarter of 2020, which is 15% lower than during the last quarter of 2019. Despite this drop, the potential for solar energy development is still at an all-time high thanks to the success of the French government’s renewable energy tenders. In order to assess what the future holds for solar in France, Solarplaza reached out to different industry leaders to discuss the way forward for solar in France.
The development of solar PV in France is supported by renewable energy tenders through a contract-for-difference system (“Complément de Rémunération''). This system, similar to the structure used in other European countries, entails that energy producers are given 20-year contracts at a price that compensates them for the difference between the market price and the tariff proposed by the producer in the dedicated tender.
So far, tenders have proven to be a good method to spur the development of both medium- and large-scale power plants in France. The country’s latest auction is a good example of that where more than 960 MW of capacity was allocated to solar projects, of which 649 MW was awarded to large-scale PV plants.
When asked about the success of the country’s tender scheme, French renewables developer Neoen stated that the current tender system seems to be efficient and effective for both the government and developers.
From the public authority’s point of view, the tender scheme makes it possible to direct the deployment of PV systems on different types of surfaces (e.g., favouring “degraded” sites), while limiting the financial burden on the state through the additional remuneration scheme. Neoen has identified this opportunity and directs a large part of its development towards degraded or brownfield sites since the development of solar projects on these types of sites are encouraged by the public authorities. Also, it makes sense by the very nature of the sites, which have little use for other purposes.
From the developer’s point of view, it provides medium-term visibility (call for tenders over several years), while making it easy to secure financing (20-year tariffs). If costs continue to fall as expected, France will have a system where projects will not cost the state anything, but will be set within a solid framework allowing them to be financed easily with a lower cost of capital. Therefore, ultimately with a lower electricity price. This will require the state to expand the land eligible for these tenders, which currently focuses on degraded land or land without clearing.
According to Olivier Carré, President of Amarenco, the state support being given to the French PV market in the form of tenders will enable the market to achieve the energy mix objectives (44 GW of solar by 2028). However, he adds that the current tender scheme should only apply to projects larger than 1 MW to free up some of the market and speed up the process. Under this threshold, Carré believes that tenders are too constraining.
French developer, CNR, states that for smaller projects, complicated projects (e.g. on polluted ground, complex topography, expensive grid connection etc.), or projects located in the north of France, tenders are still necessary. But then the question is: for how long? The answer will depend on the progress of PV technologies and the evolution of energy prices.
CNR further adds that the current PV projects will be subject to a negative Complément de Rémunération, because producers run the risk that market prices will exceed the tariff that they proposed during the tenders. As a result, developers are forced to look beyond the tender scheme for financing of large-scale projects.
As ground-mounted solar projects in France are approaching market parity quickly, some large projects are already being developed outside of the tender scheme without the need for a contract-for-difference. Most European PV markets that have reached market parity opt for power purchase agreements (PPAs) as the main method of choice of financing as they provide long-term contracts with direct consumers. In France, the situation is no different.
Recently, solar PPAs have started to pop up all across France, from rooftop airport projects to large ground-mounted plants. This is a good indicator that solar energy is now a competitive energy source in France. One of those PPAs was signed by ENGIE for a 18 MW solar plant in south-western France, which is scheduled to start operations in 2021. All of the electricity generated by the plant -estimated at 25 GWh/year- will be sold directly to ENGIE’s customers.
However, due to different market drivers, ENGIE is currently in a bearish mood on the French power market. Nevertheless, PPAs can offer the financing solutions necessary for projects affected by the decrease in market prices.
Looking ahead, both the private and the public sectors still have a long way to go if they want to push solar to the next level. Carré notes that the French authorities must put their focus on three main elements: simplifying procedures, increasing tender thresholds and regionalizing tariffs. Additionally, the French PV market should also support intermediaries actors and encourage associations between companies of different sizes.
Furthermore, he adds that the development of large-scale self-consumption systems or commercial & industrial rooftop arrays have immense potential for the French PV market. In his view, PV could be a windfall to encourage and fund the decontamination of sites and roofs (e.g. asbestos). The opportunity for these types of systems to be deployed is constantly growing as more and more of them are being developed through private PPAs.
