The heat waves, India witnessed in April 2022 were the hottest in the past 122 years, and was no relief in May either. Due to the severe heat wave sweeping the nation, electricity demand is at an all-time high as homes, businesses, and other structures turn to air conditioning for relief. As a sign of the post-pandemic recovery, the economy is experiencing massive growth. According to data from the Ministry of Power, on April 26th, the total amount of power needed to meet all of India’s demand reached an all-time high of 201.06 gigawatts (GW), exceeding the whole amount required to be satisfied the previous year. It anticipates that this demand will amount to 215-220 GW throughout May and June. As a result, the nation’s electrical demand increased by 23.5% in May.

Power outages are already commonplace in the statistics, though, as India struggles with a coal shortage in the face of rising energy demand. For instance, in April, India saw its worst power outages in more than six years. Due to a decreased pre-monsoon coal stock at power plants, the Centre for Research on Energy and Clean Air (CREA) anticipates another power crisis in July–August 2022. The Union Government has therefore instructed States to import coal.

Since this is a quick way to fix the problem that eventually leads to carbon emissions, the country needs to focus on more long-term eco-friendly methods to control the power crises in the future. Let’s understand in this article why ESS which is Energy Storage System is a simple and direct solution to this problem, as well as what obstacles the nation would face in creating an ESS setting.

Does ESS is a greener and safer system?

As the name implies, an energy storage system (ESS) is a device or collection of machines that convert electrical energy from power systems into energy storage and then release that energy when it is needed. Its ability to cut costs is one of its benefits. For instance, the British government estimates that by 2050, innovations like battery storage systems could save the country’s energy system up to £40 billion, eventually lowering consumers’ energy costs.

As India strives to meet 50% of its electricity needs through renewable sources by 2030 and eventually become a net zero economy, an ESS ecosystem that is reliant on clean energy is a step in the right direction. Additionally, according to an estimate from the research firm BloombergNEF (BNEF), India may overtake the United States as the third-largest economy in terms of energy storage installations by 2040. According to the Central Electricity Authority, India would need 27 GW of battery storage by 2030, including 10 GW of hydro-pumped storage plants with a four-hour storage capacity.

This presents a vast opportunity for battery manufacturers in India given the economy and infrastructure’s rapid growth. Not only will this make the nation a center for R&D, but it will also encourage local production, the spirit of entrepreneurship, and investment in India, as well as reduce carbon emissions, find a solution to the yearly power issue, and save money.

There are also some hurdles in establishing robust ESS

Although ESS appears to be a solution for many issues, the nation must put in a lot of effort to build a stable ecosystem to become a major producer and exporter of ESS. India faces several difficulties, including:

• High battery prices: The biggest barrier to the adoption of energy storage systems by consumers in the residential, commercial, and industrial sectors is the high price of these systems.
• Performance and safety: These devices can regulate the frequency to keep the load on the network and the power generated in balance, and they can make the power supply for high-tech industrial facilities more dependable. In light of this, operational uncertainty cannot be ruled out as a possibility.
• Lack of adequate raw materials: Lithium, copper, nickel, and cobalt are some of the essential metals needed to create batteries, however, India lacks sufficient stocks of these substances.
• Lack of standardization: According to a report from a reputable organization, “participants in early-stage marketplaces frequently cope with varying technological requirements as well as varied processes and policies.”
