How Gore Street Capital Ensures Sustainability Remains at the Heart of the Investment Case

By Sophie Sax, Head of ESG, Gore Street Capital

When we think about the investment case for battery energy storage systems (BESS), it’s easy to assume that the sustainability element speaks for itself.

We often measure the sustainability of a battery asset by the outcomes it delivers, whether that’s renewable energy stored, improved grid resilience or carbon emissions avoided. What we don’t always see are the choices that helped create those outcomes in the first place.

From the moment an opportunity is identified, sustainability considerations sit alongside investment decisions. Next to factors such as grid connections and commercial viability, we assess environmental, social and governance risks and opportunities that could influence a project’s long-term success.

The outcomes we measure once an asset becomes operational are built on the choices made at the beginning. That’s why sustainability forms part of the investment case from day one.

Assessing ESG Risks Before Investment

A key part of the investment process is understanding the Environmental, Social and Governance (ESG) risks associated with a project before capital is committed. ESG due diligence runs alongside financial, legal and technical due diligence, helping us understand the factors that could influence a project’s long-term success.

This includes assessing:

• Environmental and biodiversity risks: evaluating environmental sensitivity, biodiversity impacts and ecosystem considerations, including whether a site is located in or near protected or biodiversity-sensitive areas. Where available, Environmental Impact Assessments (EIAs) are reviewed alongside proposed mitigation measures.
• Climate risks and resilience: assessing how physical climate risks, such as flooding, heatwaves, wildfires and other location-specific hazards could affect an asset over its lifetime and influence project design.
• Community and social considerations: reviewing community safety, land rights, land-use considerations and any potential impacts on local communities, alongside broader stakeholder engagement requirements where appropriate.
• Human rights and labour risks: assessing labour standards, supply chain practices and potential risks relating to human rights, child labour and forced labour, particularly given the critical minerals used in battery supply chains.
• Resource use, waste management and circularity: considering end-of-life battery treatment and recycling plans to support responsible resource management and circular economy principles.
• Governance and compliance risks: reviewing permitting requirements, licenses, regulatory compliance and alignment with Gore Street’s Responsible Investment Policy and ESG standards, while also expecting contractors and suppliers to meet appropriate ESG requirements.

A Consistent Framework, Applied Across Multiple Markets

Since Gore Street Capital is active across six different markets, no two investment opportunities are exactly alike.

While our ESG framework remains consistent, the sustainability risks and opportunities associated with a project can vary depending on geography. For example, climate risk assessments may identify greater exposure to heatwaves, wildfires or flooding in some locations, while other markets may present different regulatory, environmental or stakeholder considerations.

Understanding these local factors is an important part of the due diligence process. It helps us assess project-specific risks and ensure sustainability considerations are reflected in both investment decisions and asset design.

Creating Long-Term Value Through Sustainability

By understanding and addressing ESG risks early, we can reduce exposure to operational, regulatory, supply chain and climate-related challenges that may affect an asset’s long-term performance.

ESG due diligence forms part of every investment decision we make, but its role doesn’t end when an investment is approved.

From a greenfield site to a fully operational battery storage asset, sustainability considerations continue to shape how projects are developed, constructed, and managed. This includes everything from supply chain due diligence and contractor selection to health and safety and operational performance.

After all, sustainability is not only measured by the outcomes a BESS project delivers. It’s also reflected in the way those outcomes are achieved, from the risks assessed before investment to the decisions made throughout development, construction and operation.
