URL More about 1500 Walnut
1500 Walnut was originally supposed to replace an ineffective cooling system. Ice storage was justified by reduced demand charges. As caps came off in PA, the demand charges were reduced and demand savings became hard to find. Tozour Energy and Viridity came in to modify the system to change the system to operate optimally as a virtual generator changing the controls to focus the entire building electrical systems, including the IceBank energy storage, to be able to transparently shed load upon a call from the electrical grid (PJM). 1500 Walnut currently participates in the PJM Capacity Market and also the PJM Economic Energy Market. Dependent on the equipment responsiveness and controllability of 1500 Walnut, the project could be considered for PJM Ancillary markets – Synch Reserve and/or Regulation in upcoming contracts.
