Having touched 1404 MW of renewable capacity as on January 31, 2020, the state-owned producer aims to add further 2847 MW to reach 4251 MW (4 GW from solar and 251 MW wind) by 2025.

Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.

The Solar Energy Corporation of India should amend the 400 MW round-the-clock supply tender to make co-location of solar, wind and storage mandatory in order to ensure optimal utilization of transmission infrastructure, says NSEFI chairman.

A Turkish research team has analyzed how big changes in temperature can affect absorbance, light transmittance and reflectivity in two types of solar glass. The scientists demonstrated lower efficiency in solar cells and the glass itself were attributable to a large number of micro-cracks and deformations on the glass surface.

An international research group has analyzed the visual impact of PV facades on buildings which include crop cultivation. Architects, PV specialists and farmers were surveyed and the results showed broad acceptance of such projects.

The projects—to be established on a build, own, operate basis—will be awarded through e-bidding and a reverse auction with a tariff ceiling of Rs 2.78 per kWh. Bidding closes on March 19.

By offering 410 KWh of cumulative battery capacity for a total cost of Rs2.51 crore, the state-owned engineer and manufacturer emerged winner in the auction which saw overwhelming response from both Lithium-ion and advanced lead-acid storage providers.

By engineering the structure of a hard carbon electrode, scientists at the CIC energIGUNE research center have created an ‘ultrafast battery’ which has been shown to combine the energy density of a lithium device with the fast discharge times normally associated with supercapacitors.

Leveraging Triton Solar’s battery technology and Ushva’s experienced team from IIT Bombay, the strategic alliance aims to develop one-of-a-kind car with the longest travel range on a single charge and unique user experience.

Tariff ceiling is fixed at Rs 4 per unit for ground-mounted, grid-connected solar projects that will come up across four regions of the state. The projects are to be developed on build-own-operate basis for supply of power to Assam Power Distribution Company Limited for a period of 25 years. Bidding closes on February 21.
