What are the risks of using an energy storage system in a building?

2 Cybersecurity threats

Another risk of using an ESS in a building is the exposure to cyberattacks that can compromise the performance, reliability, or safety of the system. ESS are often connected to the internet or other networks, which can make them vulnerable to hackers who can access, manipulate, or disrupt the data or controls of the system. For example, hackers can alter the charging or discharging schedules of the ESS, cause damage to the equipment, or create power fluctuations that can affect the grid or the building. To protect ESS from cyberattacks, ESS should have robust encryption, authentication, and monitoring mechanisms, as well as regular updates and backups.

3 Regulatory barriers

A third risk of using an ESS in a building is the uncertainty or complexity of the regulatory environment that governs the installation and operation of the system. ESS are subject to various rules and regulations at the local, state, and federal levels, which can differ depending on the type, size, location, and purpose of the system. For instance, ESS may require permits, inspections, approvals, or interconnection agreements from different authorities, such as building departments, utilities, fire departments, or grid operators. ESS may also face challenges in accessing incentives, tariffs, or markets that can affect their economic viability. To navigate the regulatory barriers, ESS owners should consult with experts, stakeholders, and policymakers, and stay informed of the changes and opportunities in the regulatory landscape.

4 Environmental impacts

A fourth risk of using an ESS in a building is the potential for negative environmental impacts that can arise from the life cycle of the system. ESS involve the extraction, processing, transportation, and disposal of various materials, such as metals, chemicals, or plastics, that can have environmental consequences, such as greenhouse gas emissions, water pollution, or resource depletion. ESS also consume energy during their operation, which can increase the carbon footprint of the building if the energy source is not renewable. To minimize the environmental impacts, ESS should be designed with efficiency, durability, and recyclability in mind, and be paired with clean energy sources.

5 Social acceptance

A fifth risk of using an ESS in a building is the lack of social acceptance or awareness of the benefits and challenges of the system. ESS are relatively new and unfamiliar technologies for many people, who may have misconceptions, fears, or resistance to their adoption. For example, some people may perceive ESS as unsafe, unreliable, or expensive, or may oppose their installation due to aesthetic, ethical, or political reasons. ESS may also face opposition from incumbent interests, such as utilities or fossil fuel industries, who may see them as a threat to their market share or revenue. To increase the social acceptance, ESS owners should engage with the community, educate the public, and address the concerns and expectations of the stakeholders.
