Viridity Energy, a leading software technology company focused on total energy management, announced today that it has been selected to operate the largest solar + storage project to be constructed in the United States. The Village of Minster, Ohio is developing a 4.2MW solar array paired with a 7.5MW storage system, integrated by S&C Electric. Energy produced by the solar array will be stored in batteries and deployed by Viridity’s market operations center in high-value applications that keep the grid in balance and provide back-up power support.
In 2009, National Grid chose ABB for a SCADA/EMS system that would allow for more modern and integrated visibility into its electric transmission and distribution networks in Massachusetts and New York. Earlier this year, the system went into service. An outage management system that was expected to be operational in New York in 2013 is now slated for early 2016.
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.
