One of the key issues facing the electric power industry is transmission vulnerability. Once more renewable energy comes online, transmission issues will likely be even more apparent. Within the electric power community, there is a big push to create one cohesive national grid, as opposed to the current system of regional grids. Proponents argue that this will help lower the price of electricity and bring more electricity produced by renewable sources to consumers. During today's E&ETV Event Coverage of a Manhattan Institute-sponsored event, panelists discuss the benefits and challenges associated with creating a national grid. Participants include Ashley Brown, executive director, Harvard Electricity Policy Group, Harvard Kennedy School of Government; Nick Brown, president and chief executive officer, Southwest Power Pool; Ashok Gupta, air and energy program director, Natural Resources Defense Council; and Philip Moeller, commissioner, Federal Energy Regulatory Commission.
