We place ESG and sustainability
at the heart of what we do –
for future generations
Our sustainability strategy
To unlock access to clean, reliable, and affordable renewable energy—while enabling a just and orderly transition.
As ACEN scales its renewable energy portfolio, sustainability remains central to how we grow, operate, and create long-term value.
PositiveCharge+ ensures that the transition to clean energy is delivered responsibly, inclusively, and with discipline, going beyond capacity growth to managing environmental impacts, supporting communities and workers, and strengthening governance across the asset lifecycle.
Through three integrated pillars—Protect+Sustain, Unite+Thrive, and Influence+Innovate—we translate ambition into action.
In a year defined by execution—on time, on budget, and safely—PositiveCharge+ reinforces that how we deliver is as important as what we build.
Together, these pillars enable ACEN to scale renewable energy responsibly, manage risks effectively, and lead the transition in a way that creates long-term value for stakeholders.
Three pillars. One integrated strategy.
Leading the transition
ACEN is advancing market-based Energy Transition Mechanisms (ETM) to enable the early retirement of coal—demonstrating how decarbonization can be both responsible and investable, while supporting a just and orderly transition.

Our materiality process
To determine economic, environmental, social and governance issues that are important to ACEN and our stakeholders, we conducted a series of materiality exercises in collaboration with an external consultant and business unit heads. identifying topics that are important to ACEN both financially and from an external impact perspective.
Our material ESG issues were updated to reflect our engagements with investors, rating institutions, and other stakeholder concerns regarding ESG. This was supplemented by research activities on the latest developments around sustainability reporting frameworks and industry-specific sustainability issues. Roadshows were also conducted with our leadership team and the board-level Sustainability Committee to validate our material ESG issues and identify strategic action plans around key ESG issues moving forward.
We conduct the materiality process every 1-2 years to ensure that material ESG topics and our ESG strategy are continuously updated to ensure relevance to our stakeholders.

Our ESG Policy
Paving the way to integrate sustainability in the way we work and influence our decision-making on strategy, capital allocation, operations, governance, and culture is our ESG Policy, with the aim to deliver long-term value for all our stakeholders.
As part of our sustainability commitment, we implement the Environmental and Social Management System (ESMS) to manage E&S risks and impacts throughout the life cycle of our projects. Through the ESMS, we are able to identify and assess E&S risks to develop appropriate action plans and mitigation measures.
Our ESMS Process
We proactively manage environmental and social (E&S) risks and opportunities through a strengthened Environment and Social Management System (ESMS).
In 2025, we aligned the ESMS more clearly to the full project lifecycle—from early area due diligence and site finalization through construction, operations, and periodic reviews—to ensure safeguards are embedded at key decision points and maintained over time.
Our enhanced ESMS provides a lifecycle- based framework that guides teams through systematic risk identification, meaningful stakeholder engagement, development
of appropriate management plans, and structured approvals and monitoring. This approach strengthens consistency across projects to ensure safeguards are effectively applied from planning through operations.
