Connecting to the main grid saves a lot of money allowing each state to build and manage less power stations so that there is makeup electricity available during plant refueling and maintenance outages. The downside is that you must comply with a broader range of safety regulations and be able to provide neighbors with power during unplanned events. The power company in Virginia is part of a multi state cooperative, years ago we had to keep 20% on the grid above our normal demand so there was always capacity to pickup the loss of a power station. Don't know if this is still the case because there haven't been any major power plants built in Virginia since 1980.
Virginia is currently building one of the largest wind farms in the Atlantic ocean 25 miles off the coast. I expect it will be a major failure, the cost is prohibitive based on the projected lifespan of the equipment.
