Evolving Technologies, Outdated Regulations Impact Mid-Atlantic Generation Permitting
Energy-generation permitting in the Mid-Atlantic continues to evolve in 2026 not through wholesale deregulation or uniform acceleration, but through procedural and permitting reform and the potential allocation of generation development authority to public utilities. States are enacting these changes to meet the reality of reliability concerns, transmission constraints, large load-growth, and to address frequent obstruction of energy projects by local government.

Understanding Cable Rejuvenation: A Modern Approach to Grid Reliability
For more than 60 years, polyethylene (PE) and ethylene-propylene rubber (EPR) underground cables have powered communities, industries, and progress. The hope was these cables could last decades before needing to be replaced, but due to water treeing—microscopic moisture-induced formations that degrade insulation and threaten reliability, they’re aging more rapidly than expected. With traditional replacement being costly and labor-intensive, it was time for a new solution.
