EV charging infrastructure planning and rollout for Bengaluru : ISGF

BESCOM is the State Nodal Agency for establishing EV charging infrastructure in Karnataka. BESCOM serves about 12 million users in Bengaluru and the surrounding districts of Kolar, Tumakur, Ramanagara, Chikkaballapur, Chitradurga, and Davanagere. BESCOM, the state-owned power distribution corporation, has long been a leader in technology adoption.

In 2017, the Karnataka government published an Electric Vehicles and Energy Storage Policy with the goal of making Bengaluru the country's EV capital. Accordingly, BESCOM has already installed 136 charging stations at 74 places in Bengaluru City (32 DC fast-chargers at 15 locations and 104 AC chargers at 74 locations), and is accelerating the process of installing 1000 charging stations.

With experience operating 136 charging stations, BESCOM recognised the importance of examining the distribution grid's capacity to handle the EV load. In many regions, grid upgrades may be necessary to accommodate the EV load. This update will necessitate extensive modelling studies.

BESCOM engaged the expert services of the India Smart Grid Forum (ISGF) to conduct thorough modelling studies in order to develop a plan for the implementation of EV charging infrastructure and accompanying grid modifications. ISGF conducted this study with the assistance of Shakti Sustainable Energy Foundation (SSEF).

This study report on the planning and implementation of EV charging infrastructure in Bengaluru was released in Bengaluru on 18th September 2021 by Honorable Minister for Energy, Government of Karnataka, V Sunill Kumar at the Karnataka Electric Mobility Workshop coordinated by BESCOM and ISGF.

Over 400 participants (in-person and online) attended the session, which included EV and charging station manufacturers, EV fleet operators, residential welfare association officers, and other stakeholders. G Kumar Naik, Additional Chief Secretary, Energy, Government of Kashmir; Rajendra Cholan, MD, BESCOM; Reji Kumar Pillai, President, ISGF; Chetan Maini, Co-founder, Sun Mobility; Mahesh Babu, CEO, Switch Mobility India and COO, Switch Mobility Global; Girish Ghatikar, Electric Power Research Institute, USA; and Shashi Verma, Director and Chief Technology Officer, Transport for London, addressed the workshop.

Modeling studies were conducted on twelve 11 kV feeders already linked to EV charging stations. On these feeders, detailed assessments were undertaken for various scenarios of EV load and rooftop solar PV penetration in the years 2020, 2022, and 2025. The study's findings have resulted in recommendations for distribution grid upgrades to accommodate EV loads in various situations.

Additionally, the paper identifies optimal areas in Bengaluru for the establishment of EV Charging Stations. This paper includes an analysis of the business models for EV charging stations as well as recommendations for software platforms for managing EV charging stations.
