Bay Area Internet Solutions, a Silicon Valley colocation company whose new data center in Santa Clara has been recognized for being built to an energy efficient design, has completed the second expansion phase of the facility to accommodate a new unnamed wholesale customer, whose equipment has been installed.

The company increased its infrastructure's power capacity by 6MW. The facility is now served by two 9MW utility feeders, with current generator back-up capacity of 10MW. An additional 9MW feeder has been installed to be activated during the third expansion phase.

BAIS President and CEO Tom Wye said in a statement he was proud of being able to complete the expansion in a short period of time. According company spokeswoman Soheila Soheil, the expansion started in May and was completed at the end of July.

"BAIS was able to accomplish this increase in high-density power because the site was designed and architected to accommodate incremental growth," Wye said.

Soheil said the expansion project consisted of expanding electrical and mechanical infrastructure, since the raised floor was already in place. The expansion included installation of three additional 2MW generators, bringing the total to five. It also included adding new switch gear, PDU's, UPS systems and other components on the electrical side.

The mechanical upgrade included new CRAC units, chiller pumps, condenser water pumps and a cooling tower.

In March, BAIS announced that its power provider, publically owned Silicon Valley Power, had awarded it a $750,000 rebate on electricity purchases for the facility's energy saving features, including a large airside economizer, precision cooling systems and the use of cold-aisle containment.
