February 11, 2002 by Jeff Shepard

The California Energy Commission (Sacramento, CA) has certified Capstone Turbine Corp.’s (Chatsworth, CA) 30kW and 60kW MicroTurbine energy systems as the first and (so far) the only products that comply with the requirements of its "Rule 21" grid interconnection distributed generation (DG) standard.

"The CEC and all of California's major utilities spent more than a year jointly developing the landmark Rule 21 distributed generation interconnection standard," said Ake Almgren, president and CEO of

Capstone Turbine. "We are pleased that our innovative microturbine systems have now officially been certified as being safe for interconnection to the grid. We think this is a significant step toward growing distributed generation market access in California, and for Capstone differentiating its products in the California market."
