BHEL Issues Tender for Battery Energy Storage Systems at Three Locations in Delhi

Bharat Heavy Electricals Limited (BHEL) has floated a tender for 410 kWh/415 kW of battery energy storage systems (BESS) at three sites in Delhi.

The scope of work includes planning, design, engineering, supply, installation, testing, commissioning, and demonstration of all the equipment involved. The supplier is also expected to provide a one-year warranty for the systems and a comprehensive annual maintenance contract (AMC) for the complete system (including the battery) for five years after the expiry of the warranty period.

The tender documents said that the purchase order would be on a turn-key basis, and all the work – including delivery, installation, and commissioning – should be completed within 21 weeks from the date of signing the purchase order. The deadline for submission of bids is August 18, 2020. No earnest money deposit would be required to participate in this tender.

The tender documents called for the installation of a 230 kWh/125 kW system at Taimoor Nagar, New Friends Colony, a 120 kWh/240 kW system at Dwarka (Ispatika Apartments), and a 60 kWh/50 kW system at TERI School of Advanced Studies, Vasant Kunj Institutional Area, in New Delhi. The locations have been divided into Category A, B, and C. In the first category, BESS would be used to manage the overload of a distribution transformer serving mainly residential consumers. In Category B, it would supply back-up power gated group housing society during power outages, and in Category C, the BESS at TERI would be charged during off-peak hours and discharged during peak hours. This application aims to demonstrate BESS operations with the difference in prices during a day at a constant rate. Apart from this, the system would be used for research work within the technical constraints of battery technology.
