American Electric Power owns the largest electricity transmission system in the US
The American Electric Power Company (AEP) is one of the largest electricity producers in the US, owning nearly 38,000 megawatts of generating capacity. AEP also owns the largest electricity transmission system in the country, with a network of nearly 39,000 miles (63,000 km). This includes 765 kilovolt ultra-high voltage transmission lines, more than all other US transmission systems combined.
AEP's transmission system provides about 10% of the electricity demand in the Eastern Interconnection, which is an interconnected transmission system that covers 38 eastern and central US states and eastern Canada. It also provides approximately 11% of the electricity demand in the Electric Reliability Council of Texas, which covers much of the state.
AEP has a long history in the US, dating back to 1906 when it was incorporated as the American Gas and Electric Company. It replaced the Electric Company of America, a holding company that had existed since 1899. Over the years, AEP has expanded and diversified its operations, and it now has several utility units operating under different names, such as AEP Ohio, AEP Texas, Appalachian Power, Indiana Michigan Power, Kentucky Power, Public Service Company of Oklahoma, and Southwestern Electric Power.
AEP has also been involved in various projects and partnerships to improve and modernize the US electric power grid. For example, in 2008, AEP formed a joint venture with Duke Energy to build and own new electric transmission assets. AEP has also proposed the Potomac-Appalachian Transmission Highline (PATH), a 765 kilovolt transmission line that would incorporate new technology to reduce carbon dioxide emissions and allow for the transmission of renewable energy sources.

Southern Company is committed to innovation, resilience, and sustainability, with a goal of achieving net-zero greenhouse gas emissions by 2050. The company has taken significant steps towards this goal, such as investing in renewable power projects and developing new nuclear units in the U.S. For instance, in 2011, Southern Company, in collaboration with Turner Renewable Energy, acquired a 30 MW solar project in Cimarron, New Mexico. Additionally, Southern Company's Plant Vogtle provides carbon-free, nuclear energy to power over 1 million homes and businesses across Georgia.
Southern Company's subsidiaries are actively involved in the optimization of natural gas assets, wholesale energy marketing, and transmission business. The company has a vast infrastructure network, managing over 27,000 miles of transmission lines, 3,700 substations, and 300,000 acres of right of way.
Despite its recent focus on sustainability, Southern Company has faced criticism for its historical funding of climate change denial. Between 1993 and 2004, the company spent over $62 million on organizations spreading disinformation about climate change. They sponsored campaigns against limiting greenhouse gas emissions and delaying the transition to renewable energy sources.
In summary, Southern Company is a major player in the U.S. energy sector, providing electricity and gas utilities to millions of customers across multiple states. While the company has recently emphasized its commitment to sustainability and renewable energy, its past involvement in climate disinformation campaigns has drawn significant scrutiny.
