Roofsol Energy Pvt Ltd has signed a long-term 25-year Power Purchase Agreement (PPA) with NCL Industries Limited, also known for its Nagarjuna Cement brand, to supply solar power to the company’s integrated cement manufacturing and grinding facilities across Andhra Pradesh and Telangana.
The agreement marks an important step in NCL Industries’ strategy to transition toward cleaner and more sustainable energy sources for its energy-intensive industrial operations. Under the PPA, Roofsol Energy will design, develop, own, and operate rooftop solar power plants across multiple Nagarjuna Cement facilities, enabling long-term access to renewable energy without upfront capital expenditure.
Supporting Sustainable Cement Manufacturing
Cement manufacturing is among the most energy-intensive industrial processes, with electricity consumption accounting for a significant share of operational costs and carbon emissions. By entering into a long-term solar PPA, NCL Industries aims to improve energy cost stability, reduce exposure to grid power price volatility, and lower its overall carbon footprint.
The rooftop solar installations will be deployed across Nagarjuna Cement’s operational sites in Andhra Pradesh and Telangana, contributing directly to the company’s clean energy procurement portfolio. The solar power generated under the agreement is expected to support energy efficiency objectives while aligning operations with broader sustainability and decarbonisation goals.
Industry experts note that long-term PPAs are increasingly being adopted by cement and other heavy industries as a practical pathway to integrate renewable energy at scale while maintaining operational reliability.
Project Scope and Execution Model
As part of the agreement, Roofsol Energy will be responsible for the end-to-end execution of the rooftop solar projects, including engineering, procurement, construction, and long-term operations and maintenance. The ownership and operational responsibility of the solar assets will remain with Roofsol Energy for the duration of the PPA, ensuring performance accountability and consistent energy delivery.
The rooftop solar systems are expected to leverage available roof space across manufacturing and grinding units, optimising land use while enabling decentralised power generation close to the point of consumption. This approach reduces transmission losses and enhances energy efficiency for industrial users.
Roofsol Energy stated that the project reflects its continued focus on delivering high-performance rooftop solar solutions for industrial and commercial consumers, supported by technical expertise, standardised project execution, and long-term asset management capabilities.
Profile of NCL Industries Limited
NCL Industries Limited is a diversified manufacturing company with a strong presence in India’s construction materials sector. The company produces a wide range of products, including Ordinary Portland Cement (OPC), Portland Pozzolana Cement (PPC), particle boards, ready-mix concrete (RMC), and allied building materials.
With modern manufacturing facilities and a robust distribution network, NCL Industries supplies infrastructure and construction projects across multiple regions in India. The adoption of rooftop solar under a long-term PPA further strengthens the company’s commitment to sustainable manufacturing practices and responsible resource management.
The solar initiative also aligns with increasing expectations from regulators, investors, and customers for industrial players to demonstrate measurable progress toward environmental sustainability.
Growing Trend of Long-Term Solar PPAs
The Roofsol Energy–NCL Industries agreement highlights a broader trend of energy-intensive industries adopting long-term solar PPAs to meet clean energy targets while ensuring predictability in power costs. For industrial consumers, such arrangements offer multiple benefits, including reduced electricity expenses, improved energy security, and compliance with ESG and sustainability frameworks.
For renewable energy developers like Roofsol Energy, long-term PPAs provide stable revenue visibility and enable scalable deployment of rooftop solar assets across industrial clusters.
India’s rooftop solar segment continues to gain momentum, particularly in the commercial and industrial (C&I) category, supported by policy incentives, falling solar costs, and growing corporate sustainability commitments.
Advancing the Clean Energy Transition
The 25-year PPA underscores how partnerships between renewable energy providers and industrial manufacturers can play a critical role in accelerating India’s clean energy transition. By integrating solar power into core manufacturing operations, companies can significantly reduce emissions while maintaining competitiveness in a cost-sensitive market.
As India advances toward its national renewable energy and decarbonisation targets, such long-term collaborations are expected to become increasingly central to the country’s industrial energy landscape.
