DSM's Integration in India's Energy Landscape (Part II)

Demand Side Management (DSM) has emerged as a key strategy for optimizing energy usage while balancing demand and supply in the grid. It plays a critical role in improving energy efficiency and sustainability across the nation.

India's power sector is undergoing a transformative shift, not just through advancements in generation and infrastructure but also by focusing on smarter, more efficient energy consumption. In this context, Demand Side Management (DSM) has emerged as a key strategy for optimizing energy usage while balancing demand and supply in the grid. By encouraging end-users—residential, industrial, commercial, etc.—to adapt their consumption patterns, DSM plays a critical role in improving energy efficiency and sustainability across the nation. In this blog, we will discuss the core concepts of DSM, explore significant energy efficiency initiatives, and highlight sustainability programs.

Demand Side Management (DSM)
Demand-side management is described as the planning, implementation, and monitoring of a utility’s activities (beyond the consumer meter) designed to encourage customers to amend their electricity consumption patterns, in terms of electricity demand level and timing, to help the customers, use electricity more efficiently.

It is a domain that focuses on modifying energy usage to meet a utility’s load-shape objectives by utilizing strategies like,

i. Peak clipping is a traditional demand-side management (DSM) strategy that reduces utility loads during peak demand periods.

ii. Load shifting is the reduction of utility loads during periods of peak demand while at the same time building loads in off-peak periods. Load shifting typically does not substantially alter total electricity sales.

iii. Valley filling is the improvement of the system load factor by building load in off-peak periods.

iv. Conservation is the reduction of utility loads, more or less equally, during all or most hours of the day.

v. Load building is the increase of utility loads, more or less equally, during all or most hours of the day.

vi. Flexibility Utility Load Shape refers to programs that set up utility options to alter customer energy consumption on an as-needed basis, as in interruptible/curtailable agreements.

DSM encompasses a variety of measures and strategies, including energy efficiency initiatives, demand response programs, time-of-use pricing, and load-shifting techniques. Several states in India have implemented successful DSM initiatives to manage electricity demand more effectively and enhance overall grid stability.

Some of the Demand Side Management (DSM) programs involve:

1. Standard & Labelling Program (S&L)

S&L is an initiative program to help consumers make an informed choice about various energy-consuming appliances, in terms of energy savings, that would result based on each appliance’s energy efficiency performance. This scheme also helps the consumer determine the cost-saving potential of the marketed household and other equipment.
Appliances such as refrigerators, air conditioners, washing machines, and televisions are labelled with star ratings, with higher star ratings indicating greater energy efficiency.
The program was launched in 2006 and is presently invoked for 19 equipment/appliances. The other appliances are presently under the voluntary labelling phase.
During the XII plan, the Standards and Labelling program will target at least 3 more new equipment/appliances including the up-gradation of energy performance standards for equipment/appliances covered during the XI Plan.

2. Energy Conservation Building Codes

The Energy Conservation Building Code (ECBC) was developed by Govt. of India for new commercial buildings on 27th May 2007. ECBC sets minimum energy standards for new commercial buildings having a connected load of 100kW or contract demand of 120 KVA and above.
To promote a market, pull for energy-efficient buildings, the Bureau of Energy Efficiency developed a voluntary Star Rating Programme for buildings based on the actual performance of a building, in terms of energy usage in the building over its area expressed in kWh/sq. m/year.
Currently, the Voluntary Star Labelling program for 4 categories of buildings (day-use office buildings/BPOs/Shopping malls/Hospitals) has been developed and put in the public domain.

3. National Mission for Enhanced Energy Efficiency (NMEEE)

NMEEE is the mission under the National Action Plan on Climate Change (NAPCC). It aims to strengthen the market for energy efficiency by creating conducive regulatory and policy regime and has envisioned promoting innovative and sustainable business models to the energy efficiency sector.
It seeks to upscale the efforts to unlock the market for energy efficiency which is estimated to be around Rs. 74,000 crore and help achieve a total avoided capacity addition of 19,598 MW, fuel savings of around 23 million tonnes per year, and greenhouse gas emissions reductions of 98.55 million tonnes per year at its full implementation stage.
NMEEE further has four initiatives to enhance energy efficiency in energy-intensive industries:
- Perform Achieve and Trade Scheme (PAT)
- Market Transformation for Energy Efficiency (MTEE)
- Energy Efficiency Financing Platform (EEFP)
- Framework for Energy Efficient Economic Development (FEEED)

4. Agri-DSM

The Agriculture DSM (Ag-DSM) project aims to replace inefficient irrigation pumps with highly efficient star-rated pumps. In the initial phase, 5 states - Maharashtra, Gujarat, Rajasthan, Punjab and Tamil Nadu- were selected to implement the Ag-DSM program. This can lead to significant energy savings, estimated to be around 30-40%.
The Agri-DSM program has significant potential to reduce energy consumption and improve agricultural productivity in India, but it also faces challenges that need to be addressed to ensure its success.

5. Demand Response (DR)

Demand response programs incentivize consumers to reduce or shift their electricity usage during peak demand periods. By participating in demand response programs, consumers help balance supply and demand.
DR has the potential to enhance grid stability by reducing peak demand during high-load periods, thereby avoiding grid congestion and potential blackouts.

However, while these initiatives are crucial, they also bring to light the persistent challenges within India's power sector—such as aging infrastructure, regulatory bottlenecks, and the ever-growing demand-supply gap. In the next part, we will discuss the critical issues and explore their impact on the broader Indian economy.
