In the energy space, Brogan has represented clients in the purchase and sale of regulated gas and electric utilities in over a dozen states and abroad. He has extensive experience with acquisitions and joint ventures involving energy infrastructure assets, including coal, natural gas, hydro, wind, solar, and nuclear power plants, battery energy storage systems, and gas pipeline systems.
