Ongoing sea change at the Navy Yard

What a year the rejuvenated Navy Yard in South Philadelphia is having.

Tasty Baking Co. opened its new bakery last spring. Federal Reserve Chairman Ben Bernanke took a tour there in May. A research consortium led by Pennsylvania State University landed $129 million in federal funds in August to develop an “energy innovation hub.”

Earlier this week, we learned a bidder has been selected to develop a new marine terminal - the first in 50 years.

On Wednesday afternoon, Mayor Nutter and Philadelphia’s chief technology officer, Allan Frank, will be on hand to officially welcome a $25 million data center that opened in September. Philadelphia Technology Park, in essence a data center for hire, was developed by a Baltimore-based Enterprise Technology Parks L.L.C.

Finally, on Friday morning, the mayor will go to the yard again to meet up with Gov. Rendell and trumpet the opening of the North American headquarters of Mark Group, a United Kingdom-based energy-efficiency company.
