India is moving aggressively in its mission to achieve its clean energy transition goal. As per the data released by the Ministry of New and Renewable Energy, India has surpassed 300 GW or 60 per cent of its non-fossil fuel power generation capacity target of 500 GW by 2030. The objective is pretty clear – adding more renewable energy generation capability.
Solar power has played a central role in that journey. It contributed 164.59 GW, taking up the largest share in the country’s renewable energy capacity. Solar power is playing a key role in helping businesses and the wider power system access cleaner and competitively priced electricity and achieving energy security. Having said that, in the next phase of energy transition, however, the focus will be on how effectively that renewable energy can be leveraged.
Solar power generation is inherently linked to the availability of sunlight and at the same time electricity demand continues throughout the day. As renewable energy adoption gains momentum and generation capacity expands, striking a balance between the scale of solar energy generation and real-time power demand becomes increasingly important. This is where energy-storage technology becomes important.
Battery Energy Storage Systems (BESS) can provide the flexibility to spread energy transmission across time phases. At an industrial unit, for example, energy storage is required to manage peak demand, thus improving the utilisation of renewable energy or providing greater control over when electricity is consumed. In addition, storage can create a more flexible and responsive grid systems. Energy storage and grid are not simply two separate technologies. Together, they can form a broader energy infrastructure strategy.
For businesses, this is particularly relevant. The energy conversation has moved beyond the periphery of electricity costs. Companies are increasingly looking at the reliability of supply especially during the peak-demand phases, exposure to changing tariffs, sustainability objectives and the ability to manage their energy requirements over the long term.
A solar plant can generate electricity at a competitive cost, but power generation is only one part of the equation. The larger question is how that generation can be aligned with the actual demand patterns.
This is where technologically advanced storage system can add another layer of flexibility. The combination of solar, grid and BESS allow businesses to rethink more actively about their energy profile. Energy generated during one period can potentially be stored and used when it has greater operational value. The objective is not simply to add battery storage to a solar plant. It is about designing an effective energy system around the intended use.
That also means the economics of storage need to be taken into account. The price of a battery or the cost per MWh is an important consideration. But, that is not the entire story. The utility of a BESS depends on how it is designed, the operating profile of the facility, tariff structures, requirement cycles, utilisation and the role that reliability and flexibility play in the business.
This is why a standardised approach to develop a BESS system may not work. The BESS solution for a manufacturing plant may look different from what it is for data centre, a renewable energy project or a grid-scale application. The industry will therefore need to move towards more application-specific thinking. Engineering, system design and lifecycle economics will become increasingly important as storage moves from early adoption into larger-scale deployment.
The boundaries between different parts of the energy ecosystem becoming less distinct. Solar generation, open access, storage and energy management are increasingly being considered together rather than as specific divisions. The industry now requires greater visibility and control over their overall energy strategy.
Technology will play an important role in making this possible. An intelligent energy management system aligns itself with the generation and consumption patterns while determining when energy should be generated, stored, drawn from the grid or consumed. Over time, better data and predictive capabilities can make these decisions more responsive to actual operating conditions. The larger goal should be to set up an energy system that can respond better to changing demand.
India has already demonstrated that renewable energy can be deployed at scale. The larger goal now is to make energy more flexible, dependable and useful across different applications.
Solar will remain central to this transition and storage can help address one of its fundamental limitations: timing. When generation, storage, grid infrastructure and consumption are in sync, renewable energy can lead to a more resilient and responsive energy system.
Ultimately, the success of India’s energy transition will not be determined only by how many gigawatts of renewable capacity are added. It will also depend on how intelligently that energy is managed and stored.
