Southern Power, a leading U.S. wholesale energy provider and subsidiary of Southern Company, has made an investment into utility-scale fuel cell generation with Bloom Energy.

­The investment will support the repowering of an existing fuel cell project located on two sites in New Castle and Newark, Delaware, which currently consist of 30 megawatts (MW) of Bloom Energy Servers.

"This is an excellent project to continue the growth of our partnership with Bloom Energy," said Mark Lantrip, CEO of Southern Power.
