The United States is swiftly expanding its renewable energy capacity, driven by ambitious climate goals and significant government incentives.
However, this rapid growth brings with it heightened cybersecurity risks due to the increased complexity of the energy grid.
Smaller renewable energy companies and individual owners may be particularly vulnerable to cyberattacks, prompting calls from government agencies and industry experts for stronger cybersecurity measures to protect the nation’s critical energy infrastructure.
Growing Concerns Over Cybersecurity
As the world intensifies its efforts to boost renewable energy capacity in line with climate commitments, the U.S. government is becoming increasingly concerned about potential vulnerabilities in the country’s energy network. These vulnerabilities could open the door to cyberattacks.
Recently, the FBI issued a warning to the private sector and individual renewable energy owners about the potential for such attacks.
While major energy companies are typically well-prepared for cyberattacks, smaller firms, startups, and individual renewable energy system owners may not be, making them prime targets for hackers.
Expansion of Renewable Energy
The U.S. is aggressively expanding its renewable energy capacity to decarbonize the economy, supported by comprehensive climate policies such as the 2022 Inflation Reduction Act (IRA).
This legislation has provided a wide array of financial incentives for adopting renewable energy, encouraging more small companies and individuals to invest in clean energy systems.
The shift from fossil fuels to renewable sources has increased the contribution of renewable energy to U.S. electricity consumption to 21 percent last year.
Increasing Vulnerabilities
Although the FBI’s warning was not in response to a specific recent attack, it highlights growing concerns about the vulnerability of energy systems.
In 2019, a private renewable energy systems operator lost visibility of approximately 500 MW of wind and solar sites across California, Utah, and Wyoming.
While attacks on residential solar systems and microgrids have been rare in the past, the sector’s growth could lead to an increase in such incidents.
Government and Federal Buildings
There are also significant cybersecurity risks for the government, especially as the Biden administration plans to transition several federal buildings and transportation systems to green energy.
Under the Clean Energy for New Federal Buildings and Major Renovations of Federal Buildings Rule, federal agencies must decrease their on-site fossil fuel use by 90 percent compared to 2003 levels in projects starting between 2025 and 2029.
They must completely eliminate on-site fossil fuel use in new projects starting in 2030.
State-Level Initiatives
At the state level, the Metropolitan Washington Council of Government plans to install up to 250,000 solar rooftops by the end of the decade.
Virginia aims to generate 5,500 MW of wind and solar power by 2030. Several state departments rely heavily on these energy sources, which could put them at risk of cyberattacks as these states transition to green energy.
This is particularly concerning for the U.S. Department of Defense, the largest energy consumer in the government, which depends heavily on local electric grids.
Challenges with Rapid Development
One of the significant issues is that the rapid development and need to transition away from fossil fuels mean many renewable energy projects in the U.S. are being developed without conventional utility protocols and regulations.
Jim Hempstead, Moody’s Ratings managing director, explained, “It’s on the edge of the grid… It’s not a utility company that usually owns, operates, generates and builds these things.
It is usually a non-regulated utility, and so they’re not regulated by the state utility commission the way (traditional) utility is. And, we know that regulation is a big benefit from a credit perspective because it provides that level of oversight.”
International Consensus and Pressure
This challenge is difficult to tackle because the need for an accelerated green transition is widely agreed upon internationally by organizations such as the International Energy Agency (IEA).
However, the speed of rolling out renewable energy projects could increase the threat of cyberattacks on energy systems.
Understandably, most companies across the U.S. do not want to lag in renewable energy adoption, especially with mounting pressure to decarbonize and various financial incentives available for investing in green energy systems.
Nonetheless, they must be aware of the potential security threats this transition could entail.
Enhancing Cybersecurity Measures
The U.S. Office on Energy Efficiency and Renewable Energy has emphasized the importance of making solar energy owners and operators more cyber-aware and cyber-secure.
This includes capabilities to prevent, identify, detect, respond to, and recover from cyberattacks. The Department of Energy’s Solar Energy Technology Office (SETO) is conducting research and development projects on cybersecurity to establish secure ways to operate solar and other renewable energy projects.
However, the U.S. government must establish strict cybersecurity standards and inform owners and operators about the risks and the latest prevention measures to mitigate the risk of cyberattacks.
Conclusion
The rapid rise of renewable energy brings significant benefits for the planet but also presents new cybersecurity challenges.
As the U.S. continues to expand its renewable energy capacity, it is crucial to implement robust cybersecurity measures to protect the nation’s critical energy infrastructure from potential cyber threats.
