White Tank Solar Energy Gets to Electrical Grid



For the first time since the White Tank Branch Library & Nature Center opened to the public in November 2010, solar energy generated onsite was sent to the electrical grid.


According to Arizona Public Service officials, about 320 kilowatt-hours of electricity was produced more than needed at White Tank in February, resulting in the excess being credited to White Tank’s electricity account.  The excess electricity was directed onto APS’s electric grid system for use by other customers.


One full day’s worth of energy production for the 29,000 square-foot White Tank structure is approximately 320 kWh.


“As a LEED Platinum certified building, we are excited about this development,” said District 4 Supervisor Max Wilson, Maricopa County Board of Supervisors.  “One of our goals was to build and operate a public space that makes use of green technology to benefit our customers and the community.  White Tank’s environmentally-astute infrastructure coupled with its energy-saving practices are providing the efficiency and pay-off we had hoped for,” he said.


The 228 rooftop-mounted solar panels produce about 25% of the facility’s annual energy needs.  With the purchase of renewable energy certificates, 100% of energy brought to the site is Green-e certified.  As a result, the building enjoys a net-zero pollution rating.


White Tank Branch Library & Nature Center is the gateway to the 30,000-acre White Tank Mountain Regional Park, about 30 miles northwest of downtown Phoenix.  For more information about the library and the Maricopa County Library District, visit  For more information about the Maricopa County’s regional park system, visit
