9 self-consumption photovoltaic power plants for the Loir-et-Cher department and its colleges
AN EXEMPLARY INITIATIVE TO MITIGATE THE IMPACTS OF THE ENERGY CRISIS
Philippe Gouet, president of the Loir-et-Cher Departmental Council, unveiled this Tuesday, October 18, the first of the 9 photovoltaic power plants planned for commissioning in 2023 on the 8 colleges and the Departmental Archives building. These 9 power plants built by Enerlis, SMAC and Artelia for self-consumption will cover 82% of the electrical needs of these 9 buildings, thus limiting the additional costs linked to the increase in energy prices in 2023.
TAKE ADVANTAGE OF THE RENOVATION OF COLLEGE ROOFS TO PRODUCE ENERGY AND CONSUME IT LOCALLY
Aware of the trend increase in energy prices for several years, the president of the Department of Loir-et-Cher and his team launched a project to install photovoltaic power plants for individual self-consumption to meet the electrical needs of 8 colleges and of the departmental archives building.
The 8 colleges also required renovation of the waterproofing of their roofs, which made it possible to conveniently pool renovation work and a real strategy of local energy production and self-consumption with the installation of aggregated power. of 1.7MWp. The electricity production linked to the power plants will be capable of meeting the needs of buildings equivalent to the average annual consumption of 360 homes in France.
The buildings will consume 23% of the power produced by the 9 power plants, thus reducing energy consumption from electrical networks. The rest of the power plants' production will be re-injected into the electricity grid.
Ultimately, 100% of the colleges' consumption will be covered thanks to the installation of future power plants which will reinforce the installations already in place. These projects respond to the department's desire to build an ambitious plan to reduce its consumption and produce carbon-free energy.
LIMIT THE IMPACTS OF THE ENERGY CRISIS BY EXPLOITING THE SOLAR POTENTIAL OF PUBLIC BUILDINGS
Energy prices have experienced an exponential increase since the end of 2021, from which
local authorities are not protected by the government's price shield mechanism. Only communities with a long-term supply contract are potentially protected.
Faced with this situation of energy crisis comparable to the oil shock of 1973, energy sobriety efforts are being put in place in the short term, but a structural approach to local energy production proves to be the best alternative to limit the impact on the public finances of the department.
In 2023, the supply price of the MWh according to the Energy Regulatory Commission is estimated at €400 and €500*, i.e. a 10-fold increase in the price a year previously. Furthermore, the price of the MWh produced on average in France by photovoltaics is estimated at €100 per MWh.
The Return on Investment of the 9 photovoltaic plants is already drastically reduced by taking into account the market prices to which local authorities will be exposed in 2023.
RAISING STUDENTS, AGENTS AND OFFICIALS AWARENESS OF ENERGY CONTROL AND THE NEED TO DECARBONIZE OUR ACTIVITIES
The approach of this project also involves real reflection on the decarbonization of the
department's activities with awareness raising among department agents,
national education officials and students. Territories such as the Loir-et-Cher department thus contribute to achieving the objectives of reducing Greenhouse Gases (GHG) in order to respect the overall trajectory of +1.5°C and carbon neutrality in France for 2050.
As a relay of national policies at the local level, the president of the Loir-et-Cher department affirms through this project the essential role of local authorities in the fight against global warming
and the limitation of its effects on their citizens. .

QUOTES
“Energy renovation must include at the heart of its thinking a real strategy for
local energy production in the territories. In the energy and climate context that we are experiencing, the Departmental Council is carrying out an exemplary energy saving operation over a period of at least 20 years. It is now urgent to accelerate and generalize projects of this type. » specifies Philippe Gouet, the President of the Departmental Council of Loir-et-Cher.
“Self-consumption combined with an approach to thermal insulation and energy efficiency is certainly one of the best assets in our customers' fight against soaring energy prices and the fight against global warming. This is a large-scale replicable model for all public tertiary buildings. » says Pierre-Marie Berlingeri, Director of the Solar Business Unit of the ENERLIS group.
“Rethinking our way of constructing and renovating buildings is essential to
respond to environmental challenges and deal with the energy crisis we are experiencing. This project is the perfect illustration of this. It constitutes an opportunity for SMAC to design and propose to the Departmental Council a tailor-made solution which combines high-performance thermal insulation (to limit energy losses), sustainable waterproofing solutions and solar energy production. The benefit is twofold: sustainably lower energy bills and improve occupant comfort. » specifies Franck Davoine, President of SMAC.
“The Artelia teams are delighted to support the Loir-et-Cher Departmental Council
in this major photovoltaic project which is even more necessary in the context of the energy crisis.
Self-consumption is becoming a lever for saving energy and controlling operating costs linked to electricity, the price of which has become very high,” says Jérôme MERCIER, Director of Energy and Carbon Projects at Artelia .
ABOUT ENERLIS:
Enerlis is an independent energy group present in France and Europe. A global operator in the energy transition, Enerlis offers an integrated approach: it combines its know-how in energy efficiency and renewable energies (charging station, solar, small hydroelectricity, low-carbon hydrogen, etc.) for the building and mobility sectors . It designs, carries out and finances energy renovation projects for its public and private clients, committing to results.
Created in 2013, Enerlis achieved a turnover of 130 million euros in 2021. It now employs 200 people.
ABOUT SMAC :
SMAC's mission: To design, build and maintain the envelope of our real estate assets of today and tomorrow in an eco-responsible manner. The company thus supports its clients in the design (thanks to its design offices) and implementation of solutions intended to reduce the energy consumption of their buildings.
SMAC today has 2,100 employees spread across 60 establishments in France and four international subsidiaries (Spain, Morocco, Chile and Peru). In 2021, SMAC achieved a turnover of 405 million euros.
ABOUT ARTELIA :
Artelia is an international multidisciplinary consulting, engineering and project management group in the building, infrastructure and industrial sectors.
With 7,000 employees, Artelia is a French leader in the sector with a turnover of €745 million in 2021 and a presence in more than 40 countries in Europe, Africa, the Middle East, Asia Pacific and the Americas. Artelia is 100% owned by its managers and employees.*
