Hi Yupette,
In the event you missed Dominion Virginia Power's press release VEPCO is ensuring the Ballston-Rosslyn corridor will have an adequate supply of electrical power by constructing a new $87.3 million 3.7 mile underground power line from high voltage towers near Four Mile run to a new substation near N. Courthouse Road and Route 50.
So, the Green questions of the day are: how much solar and other alternative energy (wind turbines) could Virginia Power have installed on-site (building roofs and exteriors) in the R-B corridor for the $87.3 million and how much power would that on-site alternative energy have generated?
