San Diego officials have voted to accept a $2.4 million grant allowing the Port of San Diego to build a cold ironing facility to be operational by 2011, port officials said.

The total cost of implementing cold ironing will be about $6 million, she said: $1.9 million to power the terminal, $2.4 million for the electrical equipment and $1.7 million for public works infrastructure such as a concrete support pad, vaults, fencing, cables and a conduit. The facility would initially be able to provide power to one ship at either the Broadway or B Street terminal. Infrastructure will be built, however, to power a second ship in the future if needed, said a port spokeswoman.

The grant mandates an aggressive building schedule, requiring the port to offer cold ironing in early 2011, the spokeswoman said.

The Board of Port Commissioners voted to accept the funds in early October, but did not announce the plans until Oct. 14.
