LONGUEUIL, Quebec, April 15, 2024 – Innergex Renewable Energy Inc. (TSX: INE) (“Innergex” or the “Corporation”), the Regional County Municipality of Lotbinière ("RCM of Lotbinière") and the Abenaki Councils of Odanak and Wôlinak are pleased to announce the signing of a 30-year power purchase agreement with Hydro-Québec (S&P credit rating: AA-) for the electricity to be generated by the 100 MW community wind power project.

« The signing of this long-term contract with Hydro-Québec marks a significant milestone in the project's progress. By producing reliable, competitively priced wind energy, we will contribute to strengthening the stability of the power grid while meeting Quebec's growing energy needs. This agreement underscores our determination to support the ambitions of Canadian utilities in the energy transition, while guaranteeing ongoing revenues for our project, » said Michel Letellier, President and Chief Executive Officer of Innergex.

« The signing of the power purchase agreement with Hydro-Québec marks the culmination of a long administrative process conducted in concert with our partners, and sets in motion the actual development of the project by ensuring with the community that it is socially acceptable, both to the citizens and to the various organizations and associations concerned, all in order to meet the growing demand for renewable energy, » says Daniel Turcotte, Prefect of the RCM of Lotbinière.

« We are pleased to see the progress of our project, which is important for the prosperity of future generations, and which also recognizes our role as guardians of the Ndakina, our ancestral territory. We will continue to be involved to ensure territorial development that respects our values and traditions, » said Rick O'Bomsawin, Chief of the Abenaki Council of Odanak.

« I'm very proud to see our project reach this important milestone. It allows us to look forward to significant economic benefits for the W8banaki Nation, and the continuation of a fruitful collaboration with our partners at Innergex and the RCM of Lotbinière towards a sustainable and inclusive energy transition, » said Michel R. Bernard, Chief of the Abenaki Council of Wôlinak.

The long-term power purchase agreement is structured as a take-or-pay contract, indexed to a predefined percentage of the Consumer Price Index ("CPI"), ensuring financial stability and protection against inflation.

On January 26, 2024, the Lotbinière Ndakina wind project was selected in Hydro-Québec's call for tenders. Upon commercial commissioning, scheduled in late 2028, the project will generate enough electricity to power the equivalent of 20,000 households.

Construction of the Lotbinière Ndakina wind project will require the creation of around 200 jobs and will involve the participation of local and regional businesses. Long-term, permanent, skilled jobs will also be created during the operating period.

Interconnection and collector system costs will be reimbursed by Hydro-Québec when the facility is commissioned.

The project is subject to the execution of contracts with suppliers, and to the successful completion of permit application processes and regulatory requirements.

About the RCM of Lotbinière

Located on the south shore of Quebec City and to the west of Lévis, the RCM of Lotbinière has seen a strong growth in its territory and population (36,424 inhabitants in 2023) over the past several years. Despite this development, 98% of the RCM’s territory is in provincial agricultural zones (the second-highest agricultural GDP among all RCMs in Quebec), making the territory and agricultural activities a major component of its identity. Having been involved with the local municipality in the commissioning of the Mont-Sainte-Marguerite wind farm in Saint-Sylvestre some ten years ago, this is not the RCM's first experience. The project covered by this request for proposals is in line with the RCM's vision of sustainable development through its various planning documents adopted over the past two decades. It is also in line with the RCM's desire to promote the development of a green economy on its territory.

About the Abenaki Councils of Odanak and Wôlinak

The Abenaki Councils of Odanak and Wôlinak form the W8banaki Nation. The name W8banaki comes from the combination of the words "W8ban" (light, glow or dawn) and "Aki" (land), meaning "People of the Dawn". Proud of their cultural and linguistic heritage, before the arrival of Europeans, the W8banakiak shared vast forested areas in present-day southern Quebec, Maine, New Hampshire and Vermont, as well as parts of Massachusetts and New Brunswick. This vast area forms the Ndakina - "Our Territory" - whose name designates the ancestral territory of the W8banaki Nation. Through their knowledge of the territory and their willingness to defend the interests of their members, the Abenaki Councils of Odanak and Wôlinak are key players in any project involving the Ndakina.

Still present and active on its ancestral territory, the W8banaki Nation now numbers over 3,000 individuals, spread mainly across Quebec and Canada, as well as the United States. The communities of Odanak and W8linak, located respectively on the banks of the Alsig8ntegw and W8linaktegw (Saint-François and Bécancour rivers) in Centre-du-Québec, are the only W8banakiak settlements on the Ndakina.
