Energy Efficiency Initiatives-Completed Projects First of its kind peak shifting project in consortium with water utility of Delhi, Delhi Jal Board (DJB). After load profiling of TPDDL & DJB, suggested DJB to shift its morning operating hours (water pumping stations) by 1.5 hours, to minimize coincidence with TPDDL peak Shift in the operation time was initiated from Aug 09. Continuous monitoring & verification in progress. Key Benefits: Shift of 2 MW load from TPDDL peak DJB Peak Shifting 6
