How Environmental Due Diligence Unlocks Value for Battery Energy Storage Development
Authored by: Rachel Henke & Christopher Proce, PG, CSP
Battery energy storage systems (BESS) are creating new opportunities for property owners and developers to unlock value from industrial, commercial, and underutilized properties. As demand for grid-connected storage grows, sites that were once considered difficult to redevelop are increasingly being evaluated for BESS projects because of their existing infrastructure, available interconnection capacity, and favorable zoning characteristics.
Many of these properties, however, have long commercial and industrial histories that can introduce environmental complexities affecting acquisitions, financing, permitting, construction, and project economics. Identifying and addressing these issues early is critical to maintaining transaction certainty and keeping development schedules on track.
Environmental considerations commonly include:
- Historic contamination and legacy fill affecting excavation and disposal costs;
- Environmental liabilities associated with adjacent and prior site operations;
- Potential brownfield redevelopment opportunities and associated tax incentives;
- Potential ITC Energy Community and Brownfield Adder tax credit eligibility;
- Wetland or ecological constraints affecting permitting and regulatory approvals;
- Soil, groundwater, and waste management affecting construction sequencing and budgets; and
- Unexpected subsurface conditions that affect engineering design, construction schedule, and project costs.
For real estate transactions, environmental due diligence should be looked at as a valuable tool instead of just a “check-the-box” item to satisfy lender requirements. A thorough understanding of site conditions can influence purchase price negotiations, allocation of environmental liabilities, underwriting confidence, permitting strategy, and project scheduling. Integrating environmental planning early in the acquisition process helps reduce uncertainty and supports more informed investment decisions.
A successful redevelopment strategy should include:
- Comprehensive Environmental Due Diligence: Phase I and Phase II Environmental Site Assessments, historical operations reviews, regulatory file research, and targeted site investigations to identify potential risks before acquisition.
- Redevelopment and Permitting Strategy: Early evaluation of environmental permitting requirements including federal, state, and local wetland or waterway permits; SPDES construction stormwater coverage and SWPPP requirements; dewatering and discharge approvals; threatened or endangered species and other ecological reviews; remediation, institutional-control, or brownfield program obligations; and agency coordination requirements that could affect site design, permitting, construction sequencing, or the overall development schedule.
- Tax Credit Evaluation Support: Technical review of available site information to support legal counsel’s evaluation of potential eligibility for the Inflation Reduction Act Energy Community Bonus Credit based on brownfield status.
- Construction Risk and Health and Safety Management: Planning for soil handling, groundwater management, waste characterization, dewatering, import fill, and contingency procedures, along with project-specific Health and Safety Plans, worker exposure controls, air and vapor monitoring, and emergency response protocols. Putting these measures in place before construction begins helps protect workers, support regulatory compliance, and minimize schedule disruptions.
Roux works with property owners, developers, investors, lenders, attorneys, and municipalities throughout the lifecycle of BESS real estate projects—from site screening and acquisition through permitting, brownfield/tax-credit evaluation, remediation, construction, and redevelopment. By integrating environmental strategies into the real estate decision-making process, we help clients reduce risk, preserve project schedules, and maximize the value of their assets.
As BESS development continues to reshape the industrial real estate market, environmental strategy has become an essential component of successful site selection, acquisition, and redevelopment. Engaging an environmental consultant during the site screening or conceptual project planning stages can help to transform potential project constraints into manageable development opportunities.
