How do new environmental permitting regulations affect the deployment of battery energy storage systems

New environmental permitting regulations are poised to significantly impact the deployment of battery energy storage systems (BESS) by introducing new compliance requirements and potentially complicating project development and operation processes.

Current Regulatory Status and Upcoming Changes

• As of early 2025, BESS installations are generally not required to obtain environmental permits under frameworks such as the UK Environmental Permitting Regulations 2016 (EPR). However, there is growing governmental intent to include BESS within these permitting regimes soon, driven by increasing environmental and safety concerns associated with lithium-ion battery systems.
• In the UK, for example, the government has committed to consulting on incorporating BESS into environmental permitting regulations, reflecting a recognition of the need to manage environmental impacts more closely as BESS deployment accelerates.
• In the US, permitting processes vary by state and locality. For instance, in Minnesota, energy storage systems 10 MW or larger require review and permitting by the Public Utilities Commission, including environmental assessments, public input, and hearings before project approval.

Environmental and Safety Concerns Driving Regulation

• The rapid growth of BESS, necessary for grid stability and renewable integration, raises concerns about environmental impact, fire safety, and pollution control.
• Main environmental considerations include:
  • Potential chemical and thermal hazards like lithium-ion battery fires and thermal runaway events, which pose risks of fire and toxic emissions.
  • Impacts on air, water, and noise pollution in project siting and operation, requiring thorough environmental assessments.
  • Waste management challenges, particularly safe disposal and recycling of batteries at end-of-life, which are increasingly under regulatory scrutiny.

Effects and Implications of New Permitting Requirements

• Inclusion under environmental permitting regimes will likely mean operators must obtain permits demonstrating compliance with environmental management and pollution control standards.
• This could introduce new steps in project development such as:
  • Conducting detailed environmental impact assessments (EIA) to address pollution, habitat, and community concerns.
  • Engaging with regulators and the public during permitting processes, including public comment periods and hearings.
  • Implementing rigorous safety and fire prevention measures based on recognized codes like NFPA 855, UL 9540 series, and International Fire Code to mitigate battery risks.
  • Potentially navigating increased zoning restrictions and the need for conditional use permits or variances, which can slow project approval and increase costs.
• Authorities having jurisdiction (AHJ) often lack experience with BESS technology, which can delay permitting and require early, proactive engagement with local officials to clarify safety, environmental and technical issues.
• Developers and operators may also be tasked with creating detailed management plans including thermal runaway prevention, site restoration, and waste recycling strategies.

Industry and Government Collaboration

• Effective regulation will require collaboration between energy storage developers, government partners, first responders, and regulators to devise clear, flexible, and safety-oriented permitting standards suited to the unique nature of BESS.
• Proactive communication, adherence to evolving international and national standards, and integration of safety innovations will be critical for smooth project execution.

Summary Table of Key Impacts of New Environmental Permitting Regulations on BESS Deployment

In conclusion, new and evolving environmental permitting regulations will impose additional procedural, technical, and safety requirements on BESS projects, potentially slowing deployment timelines and increasing costs but improving environmental and community outcomes. Early planning, close cooperation with authorities, and adherence to emerging standards are essential strategies for successful BESS project development under these regulatory changes.
