ASIA CLEAN ENERGY FORUM WORKSHOP

Diesel Generator Replacement with Lithium-ion Batteries

14 June 2022 (Tuesday)
Time: 05:30 – 07:00 PM (INDIA TIME) | 08:00 – 09:30 PM (Manila Time)

Background

Delivering reliable 24x7 services is the primary objective of every large building for which uninterrupted power supply is essential. Diesel generating (DG) sets are commonly used in developing countries for power backup for all critical infrastructure. Owing to increasing pollution levels, most cities are banning the use of DG sets. There are many alternatives to DG sets such as gas turbines and hydrogen fuel cells but due to technological maturity, reliability, safety, and efficiency the best option presently is lithium-ion battery (LiB) based energy storage systems or BESS.

DG sets burn diesel and emit carbon dioxide, carbon monoxide, nitrogen oxides (NOx), and particulate matter (PM 2.5 and PM 10)) besides causing noise pollution. DG sets release harmful particles into the atmosphere and substantially reduce air quality in the neighborhood. Every litre of fuel burned in a DG set crates 0.73 kg of pure carbon and 2.6 kg of carbon dioxide. Battery Energy Storage System (BESS) is a rechargeable battery system that stores energy from the electric grid or any renewable energy sources and provides that energy back to the building when needed. The key components of a BESS is Lithium-ion Battery (LiB) and Battery Management Systems (BMS).

A BESS can be charged either from the grid or from solar rooftop photovoltaic (RTPV) systems installed on the building. While a typical DG set operates during the power outages which is few hours in a month, the BESS connected to the grid can support the grid 24x7 by providing frequency and voltage support and can be a great resource for renewable energy (RE) and electric vehicle (EV) integration with the electricity distribution grid.

With the present cost of diesel, one unit(kWh) of electricity produced from a DG Set in the range of 35-45 US Cents, whereas the cost of electricity from BESS will be less than half of that, even if BESS in charged with electricity bought from the grid at commercial tariff of US¢ 10~12/kWh.

Innovative business models can be introduced for replacement of DG sets with BESS which would be the fastest route to create distributed energy storage systems for the grid to build flexibility which is emerging as the key requirement for renewable energy integration with the grid.

Objectives

1. To educate and promote BESS to replace of DG sets to reduce air pollution
2. To discuss the environmental benefits from BESS and avoiding DG sets in building and complexes
3. To discuss different strategies for promotion of BESS and campaigns for awareness and adoption.
4. To discuss leveraging renewable energy for battery storage and integration with the grid
