Pedernales Electric Cooperative will hold its annual members meeting in Cedar Park on June 21.

Anyone can attend the free event. Doors open for registration at 8 a.m. at Cedar Park High School South Performing Arts Center, 2150 Cypress Creek Road. PEC planners said the event will start with a series of family-friendly activities and educational booths at 8:30 a.m.

Attendees can learn about energy conservation, electrical safety, alternative energies such as solar power, and other engineering and science topics. Guests who stay for the full meeting have chances to win door prizes including an iPad and Apple TV package, an energy-efficient TV, a laptop computer and thermostat package, and a retired PEC pickup truck.

Members can vote in PEC's 2014 elections during the event, though online and mail-in voting ended on June 13. Two candidates—incumbent William D. Boggs and Emily Pataki—are running for the District 2 seat on PEC's board of directors. Four candidates—Arnold LeVine, Judy Lawler Pokorny, incumbent Kathy Scanlon and Don Zimmerman—are running for the District 3 seat.

Elected directors serve three-year terms and are tasked with overseeing the cooperative's rates, rules and finances. Read interviews with all six director candidates here.

PEC voters will also decide whether to maintain the coop's at-large voting system in which every member can vote in any district election, or to switch to a single-district system in which only a district's members can vote for their representative on the board of directors.

Election results will be announced during PEC's business meeting at 10:30 a.m. Members can also make statements to the board, see coop reports and information, and meet coop staff.

PEC is a privately owned electric utility that powers about 250,000 businesses and homes in Central Texas, including the cities of Cedar Park and Leander. The cooperative is based in Johnson City and holds its business meetings in different member cities each year.
