Boralex Inc. has appointed Jean-Christophe Dall'Ava as executive vice-president and general manager, Europe. Succeeding Nicolas Wolff, he will be responsible for continuing the development of Boralex's activities across Europe.

Mr. Dall'Ava brings nearly 20 years of experience in the renewable energy sector, both in France and internationally. He joined Boralex in 2014, dedicating his first four years to driving the company's growth through several mergers and acquisitions, before taking the lead of the development teams. In 2019, he created the commercialization department and shaped Boralex's Europe strategy, positioning the company as a pioneer in the French power purchase agreement market.

A board member of the Syndicat des Energies Renouvelables, Mr. Dall'Ava combines deep industry expertise, a strong understanding of electricity markets and a recognized ability to unite teams around common goals. He fully embodies the values that define Boralex: respect, communication, teamwork, creativity and entrepreneurship.

"First, I want to thank Nicolas Wolff for the work accomplished over the past years and his commitment through it all. I am proud to take over today, driven by the ambition to continue implementing our 2030 strategic plan. Boralex has all the assets to succeed: a solid base of operating assets, a growing project pipeline, talented and dedicated teams I've had the privilege to work with for over a decade, and strong values guiding every decision we make. Together, we will keep innovating, creating value and fulfilling our mission: delivering renewable, affordable energy for all," said Mr. Dall'Ava.

"I extend my warmest congratulations to Jean-Christophe on his appointment. His deep knowledge of our business, his strategic vision and his passion for our mission are invaluable assets for driving our growth. I am confident his unifying and people-focused leadership will ensure continuity while opening new opportunities for Boralex in Europe. Finally, I want to sincerely thank Nicolas Wolff for his dedication and the quality of his work over the years, which have significantly contributed to expanding our European operations," said Patrick Decostre, president and chief executive officer of Boralex.

Aligned with Boralex's strategy, Mr. Dall'Ava's mandate will be to strengthen an integrated and diversified industrial model in Europe to deliver competitive renewable energy tailored to customer needs; reinforce Boralex's leadership in France while building a sustainable growth platform in the United Kingdom; and continue developing a safe, inclusive and responsible organization committed to a net-zero trajectory by 2050.
