New Jersey's infrastructure is highly developed, supporting its dense population and massive commercial base. The electrical grid is managed by the regional transmission organization PJM Interconnection, with power distributed by major utilities like PSE&G, Jersey Central Power & Light (JCP&L), and Atlantic City Electric. The state is a leader in solar energy adoption and is heavily investing in offshore wind projects off the Atlantic coast.
Water and sewer infrastructure is robust, managed by a mix of municipal authorities and private companies like New Jersey American Water. While reliable, some legacy systems in older industrial cities face challenges with aging pipes and combined sewer overflows during heavy rains.
Telecommunications and internet connectivity in New Jersey are among the best in the nation. The state boasts exceptionally high broadband penetration, with gigabit fiber-optic connections available in many municipalities, alongside near-universal 5G cellular coverage, making it an ideal environment for tech enterprises and remote work.
