EPTA’s Market Frankford line, the busiest transit line in Philadelphia and referred to locally as the “El,” has moved commuters, shoppers and visitors for more than 100 years. Moving these trains requires a large amount of electricity. In 2010, SEPTA partnered with Viridity Energy to implement a new strategy to cost-effectively reduce SEPTA’s energy consumption. The El’s electrically powered trains also have regenerative braking capabilities. When trains brake, their electric motors produce energy—a six-car train on the Market-Frankford Line can produce up to three megawatts in 15 seconds of braking. The problem is, unlike hybrid vehicles, 20th century trains were not designed with an energy storage capacity. Regenerated energy from a braking train can only be used if there is another train accelerating in the immediate area. Otherwise, the regenerated energy is wasted—dissipating as heat through resistor banks on the top of the train.
Infrastructure developer Anbaric steps into world of microgrids, pushes high-voltage DC lines in U.S.
How are microgrids helping to shape the future of the electric power sector? During today’s OnPoint, Ed Krapels, founder and CEO of Anbaric, an energy infrastructure developer, discusses his company’s recent partnership with Exelon on a series of microgrids in New York state. He also discusses the transmission and infrastructure challenges that exist with U.S. EPA’s Clean Power Plan.
The Clovis City Commission unanimously approved plugging in Tres Amigas, LLC, to a $1.655 billion industrial revenue bond —the third-highest in New Mexico history — Thursday night in what commissioners and other local officials called a major step forward for the city and the power industry as a whole.
FERC on April 9 signed off on an agreement among Tres Amigas LLC, the Southwestern Public Service Co. and the Southwest Power Pool Inc. that will enable the Tres Amigas “superstation” to interconnect with Southwestern’s transmission system.
