BHEL Issues Tenders for Setting Up 410 kWh BESS for TERI’s 3 Sites in Delhi

Bharat Heavy Electricals Limited (BHEL) has announced that it has released a tender, appealing bids from eligible firms for setting up of 410 kWh Battery Energy Storage Systems (BESS) for The Energy Resources Institute (TERI) at 3 sites in Delhi.

The scope of work for the nominated bidders will include the survey, planning, design, engineering, manufacturing, testing, insurance, supply, installation and commissioning of the BESS projects along with comprehensive maintenance under an AMC on turnkey basis. The bidders will be totally responsible for the desired performance of the offered BESS systems.

To be eligible, the bidders should have a minimum of two years of experience in executing contracts of grid-interactive BESS (viz supplied /commissioned /running) across the globe in the last five years. And, the bidders should have installed and operationalized the grid-interactive battery energy storage system(s) of cumulative installed capacity of 125 kW for 2 hours or higher, out of which at least one grid-interactive BESS should be of 30 kW for 2 hours’ capacity or, higher (in India or abroad).

Under the UI-ASSIST initiative, TERI in-association with BRPL (BSES Rajdhani Power Ltd) conducted a detailed feasibility study within the BRPL licensee area in the NCT of Delhi and has identified few selected locations to demonstrate operational use cases of grid-scale BESS on pilot-basis.

The details of BESS application(s) and size for specified locations are:

• Category-A: 990-kVA DT in Taimoor Nagar, New Friends Colony – BESS will be used to manage the overload of a Distribution Transformer (DT) serving mainly residential consumers. BESS to be installed on the LT side of DT will be charged when the loading of DT is lower than a particular threshold level and discharged when loading exceeds the defined threshold level.
• Category-B: Dwarka (Ispatika Apartments) – Herein, the proposed application of BESS is to supply the back-up power to common/ critical loads (loads such as lift, water pump and lighting load) of gated group housing society during power outages. The system will be charged from grid power and also from existing rooftop solar PV installed as and when available. Additionally, there should be a provision to charge the BESS from DG power, DG synchronisation if required.
• Category-C: TERI-School of Advanced Studies (SAS) is an institution with TOD tariff applicable for five months. In this case, BESS will be charged during off-peak hours and discharged during peak hours. This application aims to demonstrate BESS operations with a difference in prices during a day at a constant rate. During remaining times of the year, BESS operations may be used for research work within technical constraints of the battery technology
