Grids & Integration

March 30 is the last date to bid for the solar capacity tendered by NTPC Vidyut Vyapar Nigam Limited. The project—to be set up on turnkey basis—shall come up at Panchet power station of Damodar Valley Corporation and shall be awarded through domestic competitive bidding followed by reverse auction.

A report by Norwegian energy consultant DNV GL has considered the opportunity for long-term energy storage to play a role in balancing annual supply and demand fluctuations in a renewables-led grid. Using 58 years of Dutch weather and energy consumption data, the study found long-term solutions such as green hydrogen could make a valuable contribution – but perhaps not as much as some analysts believe.

The OneBox, from Indian manufacturer Vision Mechatronics, consists of a lithium battery, hybrid inverter and solar charge controller to give a hassle-free solution for electricity back-up during power outages. Solar rooftop owners are offered a grid feed feature to maximize net metering income from any excess power generated.

Presently, 55 GW of renewable (solar and wind) energy is being monitored through these centers which are equipped with artificial intelligence based forecasting and scheduling tools.

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.

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.

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.

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.

Having bagged 2.250 MW capacity in January, the Gujarat-based power generator has won four more solar projects—900 KW for JPB Fibers, 675 KW for N.J. Textile Industries, 135 KW for N.J. Texturisers and 950 KW for Sailaxmi Tex—aggregating to a capacity of 2.66 MW.
