Businesses worldwide are prioritising renewable energy to achieve sustainable growth. Rising climate concerns, depleting fossil fuel reserves and escalating energy costs are driving corporates and commercial and industrial (C&I) consumers towards green power procurement. Technological advancements have reduced costs, making solar, wind and hydro energy more accessible than ever. Beyond environmental benefits, renewables enhance financial stability and ensure regulatory compliance. As governments promote greater renewable adoption, companies are leveraging innovative procurement models to secure long-term cost savings and improve energy security.
Growing need for green power procurement
Corporates and C&I consumers are increasingly prioritising green power procurement due to multiple factors. One of the primary drivers is the global shift towards sustainability and corporate responsibility. Governments, investors and consumers are pressuring businesses to reduce their carbon footprint and align with international climate agreements such as the Paris Accord. Environmental, social and governance compliance has become a key metric for business evaluation, with companies demonstrating sustainability leadership gaining a competitive edge in the market.
Cost competitiveness is another crucial factor driving the shift towards green power. Over the past decade, the costs of renewable energy technologies such as solar and wind have declined significantly. In many cases, renewable energy offers lower long-term costs than conventional fossil-fuel-based power, making it an economically viable option for corporates. Unlike traditional energy sources, which are subject to price volatility, renewables provide price stability and predictability, allowing companies to plan their long-term energy expenditures with greater confidence.
Further, the rapid rise of digitalisation has driven exponential growth in data centres, making them major consumers of renewable group captive power due to their high energy needs. In many states, group captive power remains a cost-effective alternative to grid tariffs and third-party open access. Meanwhile, demand for distributed solar energy is surging, driven by both consumer preferences and financial incentives. Industries such as IT, automotive, electrical manufacturing, construction and metals are among the top renewable energy adopters. Currently, C&I consumers account for 40-45 per cent of India’s electricity demand, with residential adoption gaining momentum.
Regulatory support and government incentives further accelerate corporate adoption of green power. The government has implemented policies that encourage businesses to transition to renewable energy through tax incentives, open access regulations and renewable energy certificate mechanisms. Corporates are strategically leveraging these policies to meet their sustainability goals while benefiting from cost-effective power procurement.
Pathways for green power procurement
Corporates and C&I consumers have multiple options for green power procurement, each with unique advantages and challenges. One of the most direct methods is on-site renewable energy generation, where companies install solar panels, wind turbines, or other renewable energy systems on their premises. On-site generation not only reduces dependence on grid electricity but also helps lower energy costs in the long run. However, high upfront investment costs and space constraints can pose challenges, especially for businesses with limited real estate.
Another effective strategy is the use of green open access and captive power plants. Open access allows large consumers to procure renewable energy directly from independent power producers through the grid, while captive power plants involve businesses setting up their own renewable energy projects (off-site) for self-consumption. These models provide access to cost-competitive renewable power and offer long-term energy security. However, regulatory approvals, transmission constraints and additional charges such as cross-subsidy surcharges in certain states can impact their feasibility.
Power purchase agreements (PPAs) are among the most popular mechanisms for corporate renewable energy procurement. PPAs are long-term contracts between corporates and renewable energy developers, ensuring stable electricity prices for extended periods. Physical PPAs involve the direct supply of renewable energy to corporate buyers, whereas virtual PPAs function as financial agreements where companies support renewable energy projects without directly receiving the power. PPAs help businesses hedge against electricity price fluctuations and demonstrate a strong commitment to sustainability. However, they require careful contractual structuring and long-term financial planning.
Power exchange instruments such as the green term-ahead market and the green day-ahead market enable corporate consumers to purchase renewable energy directly, offering greater flexibility without lengthy PPA processes. Additionally, India is set to introduce a phased carbon market, paving the way for new business models in the renewable energy sector. Some companies opt for green tariffs and utility green programmes, where they purchase renewable energy from utilities offering green power options. This approach is relatively easy to implement as it does not require infrastructure investments. However, in some regions, green tariffs can be more expensive than standard electricity prices, which may deter widespread adoption.
Further, renewable energy certificates (RECs) provide an alternative to businesses to claim renewable energy usage without physically procuring green power. By purchasing RECs, companies can offset their carbon footprint and demonstrate commitment to sustainability. While RECs provide flexibility, they do not necessarily lead to cost savings, making them more of a reputational tool than a direct cost reduction strategy.
Regulatory scenario
India has made significant progress in enabling green power procurement for corporates and C&I consumers through favourable regulations and policies. The Green Open Access Rules, 2022 marked a major milestone by reducing the minimum eligibility limit for open access from 1 MW to 100 kW, making it more accessible for medium-sized businesses. Additionally, the waiver of transmission charges for renewable energy projects commissioned within specific timelines has made renewable power more cost-competitive.
The renewable purchase obligation framework requires obligated entities, including large industrial and commercial consumers, to source a certain percentage of their energy from renewables. This has encouraged businesses to actively seek renewable energy procurement options. Furthermore, India’s energy storage and hybrid policies are playing a crucial role in addressing the intermittency issues of renewables, making it easier for companies to integrate green power into their energy mix.
Challenges
Corporates face several challenges in green power procurement. Regulatory uncertainty remains a significant hurdle as frequent changes in open access policies and cross-subsidy surcharges can impact long-term planning. Businesses need to stay updated on evolving regulations to make informed decisions about their renewable energy procurement strategies.
Grid integration poses another challenge, as renewable energy sources such as wind and solar are inherently intermittent. Without adequate energy storage solutions, maintaining a reliable power supply can be difficult. Companies are increasingly exploring battery storage systems and hybrid renewable energy models to address this issue, but these solutions require additional investment. The high initial capital costs associated with on-site renewable energy projects and captive power plants can be a deterrent for many businesses. While the return on investment is favourable over the long term, securing upfront funding can be challenging, particularly for small and medium enterprises.
Contractual complexities in PPAs also present a challenge. Long-term commitments of 10-20 years require careful financial and legal planning, as market conditions and business needs may change over time. Companies must assess counterparty risks and ensure that contractual terms align with their long-term energy strategy.
Additionally, there is a lack of awareness and technical expertise among businesses regarding green power procurement options. Many corporates are unaware of the regulatory provisions, financial incentives and mechanisms available for renewable energy sourcing. Capacity building initiatives and knowledge-sharing platforms can help address this gap and encourage more businesses to transition towards green power.
Outlook
As corporate sustainability commitments continue to rise, the green power procurement landscape is evolving rapidly. One emerging trend is the corporate aggregation model, where multiple small-and mid-sized companies pool their demand to collectively procure renewable energy. This approach allows businesses that may not have the scale for individual PPAs to access cost-competitive green power.
Battery storage integration is gaining momentum as companies seek to overcome the intermittency challenge of renewables. Advances in energy storage technologies and declining battery costs are making it more feasible for businesses to incorporate storage solutions alongside renewable energy procurement. The adoption of blockchain technology and smart contracts is transforming renewable energy transactions by enhancing transparency and efficiency. Blockchain enables real-time tracking of renewable energy generation and consumption, ensuring authenticity and reliability in green power procurement.
Green hydrogen is emerging as a promising alternative for industrial decarbonisation. As hydrogen production costs decrease and infrastructure develops, more industries are expected to explore hydrogen-based energy solutions.
The rise of decentralised energy markets and peer-to-peer energy trading platforms is another noteworthy trend. Companies can trade excess renewable power with other businesses or consumers, creating a more dynamic and efficient energy ecosystem.
Conclusion
Green power procurement is no longer just an environmental responsibility – it is a strategic business decision that offers financial, operational and reputational benefits. Overcoming challenges such as regulatory complexities, grid integration and investment barriers will be crucial to accelerating the transition. By proactively adopting green power procurement strategies, businesses can future-proof their operations, enhance their sustainability credentials and contribute to a cleaner and more resilient energy system.
