Here are some noteworthy cleantech announcements of the day from around the world:

The Ministry of New and Renewable Energy (MNRE) has extended the self-certification of solar photovoltaic (PV) inverters under the Bureau of Indian Standards (BIS) from June 30, 2022, to December 31, 2022. The extension was granted as the industry had sought more time for compliance, considering the testing issues and the test labs’ level of preparation. However, the deadline is subject to the condition that manufacturers have valid International Electrotechnical Commission (IEC) accreditation and test reports from international test labs for the smooth implementation of the order.

The Energy and Resources Institute (TERI) and the REMC, a joint venture of the Railways Ministry and RITES, signed an agreement to collaborate on capacity building and developing renewable energy projects for the Indian Railways. The two organizations aim to collaborate on areas related to green building, performance audits, energy efficiency projects, research related to the net-zero target of Indian Railways, and renewable energy-related projects. The effort would also be to build the capacities of railway professionals in the field of sustainability and technical know-how. Both the organizations will work together to achieve the objectives of improving efficiency and net-zero emissions by 2030.

Solar energy equipment supplier Industrial Solar signed an agreement for an engineering study and first phase implementation of a concentrating solar collector for textile supplier Arvind. The order value of the design engineering is €46,000 (~$47,052). The textile company has prioritized reducing its emissions by 56% by 2030. Arvind is prioritizing implementing renewable clean energy in its manufacturing facilities which are responsible for 70% of the company’s climate impact. As part of this initiative, Arvind has stopped onboarding new suppliers with on-site coal boilers into its supply chain and instead invests in its suppliers to support them in transitioning to renewable energy sources. The planned collector field will have a capacity of almost 8.6 MTh and cover an area of 20,000 m2 to produce saturated steam at 9 bars.


Sustainable infrastructure investor Actis signed definitive transaction documents to acquire a controlling stake in Yellow Door Energy. Yellow Door Energy is the leading distributed commercial & industrial solar platform in the Middle East and Africa, with around 200 MW of secured production capacity.  The company’s mission is to advance the low carbon transition through deploying renewable technology, reducing regional business electricity costs and dependence on fossil fuels. The transaction will be funded through Actis’ Energy 5 Fund, Actis’s latest energy fund with $6 billion of investable capital to accelerate the global energy transition.
