Strengthening Energy Resilience in France
In FY26, EnerSys secured a renewable Power Purchase Agreement to supply approximately 20 GWh of wind-generated electricity annually from two wind farms in France to our Arras manufacturing facility. The agreement enhances energy supply security, provides greater long-term cost visibility, and supports our strategy to improve operational efficiency. During the first quarter, renewable energy supplied 57% of the site's electricity demand, reducing greenhouse gas emissions by approximately 148 metric tons of CO₂ while strengthening the resilience of our operations.
Energy
While energy is a fundamental input for our products, we are constantly evaluating ways to make our operations more efficient and reduce our energy usage. By maximizing the efficiency of our operations, we not only reduce our environmental footprint but also enhance our bottom line. We prioritize energy-efficient technologies and processes throughout our manufacturing facilities and supply chain, continually seeking innovative solutions to minimize energy consumption.
2030 ENERGY GOAL & PROGRESS
We are committed to reducing our energy intensity per kWh produced by 25% by 2030 compared to 2020.
*We have achieved a 15% improvement since 2020.
Water is a vital resource to all life, and EnerSys is committed to being a good water steward everywhere we do business. Water plays a crucial role in our manufacturing operations and is used for multiple processes, including preparing electrolytes, plate manufacturing, battery formation and washing finished production equipment and manufacturing areas. It is imperative that we drive efficiency in our operations, reduce our freshwater usage and reuse water wherever possible to minimize our impact on the environment.
In 2023, we continued to monitor and disclose the quantity of water withdrawn from our manufacturing facilities. In 2023, our operations utilized 892 megaliters, marking an absolute reduction of 9.7% from 2022. We prioritize using recycled water over fresh water whenever feasible, with our recycled water usage at 12% in 2023. Furthermore, we are committed to minimizing wastewater discharge from our operations, and we consistently maintain chemical and total dissolved solids levels well below regulatory requirements.
2030 WATER GOAL & PROGRESS
We are committed to reducing our water intensity per kWh of storage produced by 25% by 2030.
We have achieved a 6% improvement since 2020.

Tijuana Mexico Plant
As part of our commitment to the UN CEO Water Mandate, EnerSys is engaging in water reduction and reuse projects in water-stressed regions, like in Tijuana, and we are logging our progress in the UNGC’s Water Action Hub. Tijuana is a state where water resources are often strained as water shutoffs are increasingly common and key reservoirs are nearing all-time lows.15 The team in Tijuana implemented a water reuse project at the plant which is estimated to have reduced the plant’s city water usage by about 4,400 gallons of water per day. That’s enough water to provide more than 5,200 people with the recommended amount of daily drinking water, 3.2 Liters per day.

“This is an important and impactful initiative in a water-stressed state like Tijuana. We’re taking necessary actions to address water scarcity in the communities we operate in and make progress towards our company-wide water intensity goal.” German Fernandez |
END OF USE MANAGEMENT
At EnerSys, responsible end-of-life management is an important part of our approach to resource stewardship. Through established collection and recycling programs, we help recover valuable materials from batteries at the end of their service life, reducing the need for virgin raw materials and supporting a more resilient supply chain. By supporting certified take-back programs and responsible recycling practices, we help divert materials from landfill, recover critical resources for future manufacturing, and extend the value of materials already in circulation. These efforts reinforce our commitment to efficient resource management and responsible product lifecycle stewardship.
