The Central Electricity Regulatory Commission issued draft amendments to the Renewable Energy Certificate (REC) Regulations. The amendment proposes clearer eligibility criteria for captive projects, establishes a new timetable for REC applications by power distribution companies and open-access consumers, updates the methodology for certificate multipliers, and addresses RECs under virtual power purchase agreements. Stakeholders can submit their comments and suggestions by October 23, 2025.

India has a ground-mounted solar potential of around 3,343 GW, according to a report released by the Ministry of New and Renewable Energy and the National Institute of Solar Energy. The potential was calculated using approximately 6.69% of the total identified feasible wasteland nationwide. Apart from the well-known solar-rich regions in Rajasthan, Maharashtra, and Gujarat, which are characterized by vast wastelands and high irradiance, several other states also have significant potential due to favorable solar geometry and land-use efficiency. Rajasthan has the highest potential at 828.78 GW, followed by Maharashtra (486.68 GW), Madhya Pradesh (318.97 GW), Andhra Pradesh (299.31 GW), Gujarat (243.22 GW), Karnataka (223.28 GW), and Tamil Nadu (204.77 GW).

PFC Consulting invited bids for the establishment of an interstate transmission system to facilitate the drawal of renewable energy at the South Kalamb Substation in Maharashtra. The project will be executed on a build, own, operate, and transfer basis. Bids must be submitted by December 26, 2025. Bids will be opened on the same day. The scope of work also includes the design, engineering, procurement, erection, testing, and commissioning of the assets, as well as preparing a detailed project report, arranging financing, project management, and land acquisition. It also entails obtaining the right-of-way, statutory consent, and permits.

Renewable energy company Hero Future Energies (HFE) secured ₹10.24 billion (~$115.43 million) in funding from the State Bank of India to finance a 60 MW hybrid project in Andhra Pradesh. The project, which combines solar, wind, and storage and is contracted with the Solar Energy Corporation of India, is being built in the Kurnool district. Funding was secured through the company’s special purpose vehicle, Clean Solar Power Barmer. HFE has a global portfolio of 7.2 GW of renewable energy assets and 2.3 GWh of battery energy storage systems across India, Ukraine, Vietnam, and the UK, comprising operating or under-construction projects.

Inox Solar, a subsidiary of INOXGFL, partially commissioned 1.2 GW of its 3 GW solar module manufacturing plant in Bavla, Ahmedabad, Gujarat. The manufacturing plant was established in four months. In the next phase, Inox plans to add 1.8 GW of module manufacturing capacity to the plant. The fully automated facility produces N-type, tunnel oxide passivated contact (TOPCon) solar modules using M10 and G12R and G12 solar cells. It will also manufacture bifacial modules. Additionally, Inox is establishing a 4.8 GW integrated cell and module facility in Dhenkanal in Odisha. Inox Solar is a 100% subsidiary of Inox Clean Energy.

Solar module and cell manufacturers LONGi Green Energy Technology and JinkoSolar announced that the two companies, along with their affiliates, have reached a global settlement regarding ongoing patent disputes and related legal proceedings. Under the agreement, all worldwide patent litigation between the two companies will be terminated. Additionally, LONGi and JinkoSolar have entered into a commercial agreement that includes the cross-licensing of selected core patents. Both companies emphasized that the settlement reflects a shared recognition of the importance of intellectual property protection and a long-term commitment to fostering sustainable innovation in the solar sector.

Vietnam-based solar cell and module manufacturer, Boviet Solar Technology, added a third module manufacturing production line at its facility in Greenville, North Carolina, in the U.S., expanding its production capacity from 2 GW to 3 GW. The company added the third manufacturing line to enhance its ability to meet the U.S.’s growing demand for domestically produced solar products. The Greenville manufacturing facility’s first phase commenced operations in April this year. It produces Boviet Solar’s Gamma series monofacial and Vega series bifacial solar modules. The company had announced an investment of $249 million for the facility in April last year.

The Netherlands is holding back €277 million (~$326.75 million) that was conditionally reserved for the second and third phases of the SolarNL project, which aims to develop domestic solar manufacturing capacity. The SolarNL project was initiated with a one-time public subsidy of €312 million (~$367.21 million) to develop and scale manufacturing for three solar technologies: high-efficiency silicon heterojunction cells, flexible perovskite foils, and integrated solar products. The first phase was awarded €135 million (~$159.24 million).

At the end of 2024, price arbitrage was the leading use of utility-scale batteries, accounting for 43% in the California Independent System Operator (CAISO) and about 50% in the Electric Reliability Council of Texas (ERCOT), according to the U.S. Energy Information Administration (EIA). The survey was conducted between 2023 and 2024. Most of the U.S.’ utility-scale battery capacity is in the two electricity markets that cover much of California and Texas. By the end of 2024, CAISO had reported 11.7 GW and ERCOT had reported 8.1 GW of battery capacity. In the U.S. EIA’s annual report, operators of utility-scale batteries were asked about the common use cases of their battery systems.
