QAZAQ GREEN.   TotalEnergies, alongside Samruk-Energy and KazMunayGas, its partners in the joint venture Aktas Energy, has selected the Engineering, Procurement, and Construction (EPC) and Battery Energy Storage System (BESS) suppliers for the Mirny wind project, marking a major milestone toward the construction of Kazakhstan’s largest renewable energy project.

The Conditional Letters of Award were signed on Friday during an official ceremony at the French Ministry of Foreign Affairs in Paris, with formal agreements remaining contingent upon the Project reaching Final Investment Decision and achieving financial close.

An experienced EPC consortium

The EPC scope of the Mirny Project has been awarded to an international consortium comprising:

-        The Shanghai Institute of Mechanical and Electrical Engineering Co. Ltd (China)

-        Shanghai Electric Group Co. Ltd (China)

-        GCD Partner LLP (Kazakhstan)

Under the agreement, the consortium will be responsible for the engineering, procurement, supply, construction, and commissioning of critical infrastructure over a three-year period.

The consortium is contributing significant regional and international experience to the Mirny project, having successfully delivered renewable assets in Kazakhstan, as well as major wind farms in China.

First BESS contract for Saft in Kazakhstan

The contract for the supply, connection, and commissioning of the Battery Energy Storage System (BESS) has been awarded to Saft, a wholly owned French affiliate of TotalEnergies.

The Mirny project includes Kazakhstan’s first utility-scale energy storage facility, with total installed capacity of 300 MW (600 MWh). The advanced system is designed to protect the energy supply against the intermittency of wind power, charging from the grid and discharging energy back as requested by the system operator to ensure stability.

Saft reached a global milestone in 2025, with 10 GWh of energy storage systems deployed or under contract, powering more than 150 projects across more than thirty countries.

“We are delighted with the signing of these major EPC and BESS contracts, which marks a significant transition from planning to execution for the Mirny project”, said Olivier Jouny, Senior Vice President, Renewables at TotalEnergies. “The large-scale project is now advancing rapidly toward construction, demonstrating our unwavering commitment to delivering this flagship national wind farm on time. We are particularly proud to leverage the technological synergies within TotalEnergies by deploying Saft’s advanced storage solution, the first of its kind in the region. Saft’s battery system will do more than just store energy; it will provide critical services to stabilize the national grid, a perfect illustration of how our integrated multi-energy strategy can add tangible value to Kazakhstan’s energy security.”

“The Mirny project stands as a pivotal component in the implementation of KazMunayGas’s Low-Carbon Development Program until 2060,” says Zakariya Daniyar, Deputy General Director, KMG Green Energy, “Bringing 1 GW of renewable energy capacity online will allow us to substantially lower the carbon intensity of our operations and make a meaningful contribution to Kazakhstan’s targets under the Paris Agreement. By integrating cutting-edge energy storage solutions alongside our partners, TotalEnergies and Samruk-Energy, we underscore our dedication not only to environmental sustainability but also to the technological advancement of the national energy landscape.”

“At Saft, we’ve been providing batteries for critical infrastructure in Kazakhstan for more than twenty years”, said Cédric Duclos, CEO, Saft. “This is our first BESS project in the country, and we are honored to play a bigger role in Kazakhstan’s vision for the energy of the future. In recent years, we have rapidly strengthened our position in the global energy storage market, with 10 GWh now installed or under construction. This momentum reflects our commitment to innovation and reliability, as demonstrated by advanced ESS projects that support grid stability, like Mirny.”

“As the EPC contractor for the 1GW Mirny project, Shanghai Electric is honored by the signing of these EPC contracts. We will leverage our professional capabilities to support TotalEnergies in delivering this national benchmark project for Kazakhstan on schedule”, said Lu Yu，Chairman，Shanghai Institute of Mechanical and Electrical Engineering Co. “We will fully cooperate with the project partners to ensure the wind power project plays its role in stabilizing the local power grid. Drawing on our global experience in wind power projects, we will integrate high-quality EPC services into local energy development, helping Kazakhstan strengthen its energy security while setting a model for China-Kazakhstan green energy cooperation.”

“As a Kazakhstani company with extensive experience in delivering renewable energy projects across the country, we are proud to contribute our expertise to the implementation of the 1 GW Mirny Project. Participation in the execution of the 1 GW Mirny Project, which is a significant milestone in the renewable energy sector in Kazakhstan, is strategically important for us as a local EPC company and reflects our long-term commitment to supporting Kazakhstan’s transition to sustainable energy”, added Nurbek Abdeshev, Founder, GCD Partner LLP. “We highly value our partnership with TotalEnergies and remain focused on ensuring that Project goals will be achieved to the highest professional standards. Together, we are working toward a shared objective - delivering reliable, efficient, and sustainable energy solutions for the future of Kazakhstan.”

About 1 GW Mirny project

In November 2022, the Governments of Kazakhstan and France signed a Special Agreement on Cooperation in Combating Global Warming, marking a major milestone in their long-term partnership for clean energy and climate action and paving the way for the development of the 1 GW Mirny wind farm.

With a 25-year Power Purchase Agreement (PPA) signed in June 2023, the Mirny project stands as Kazakhstan’s first and most ambitious renewable energy initiative. It is being developed by Aktas Energy, the partnership between TotalEnergies, Samruk-Energy JSC and KazMunayGas, under an investment agreement signed with the Government of Kazakhstan in December 2023 and restated in March 2024.

With installed capacity of 1 GW and an integrated 300 MW/600 MWh Battery Energy Storage System, the project will deliver approximately 4 billion kWh of clean electricity annually—enough to power more than one million households—while preventing 3.5 million tons of CO₂ emissions each year. Construction is scheduled to begin in 2026, strengthening Kazakhstan’s energy security and supporting its commitment to get to net zero by 2060. Construction is being carried out in Zhambyl, in the southern part of Kazakhstan. Commissioning is planned for 2028.
