Delhi discom deploys digital data platform for solar energy management

BSES Yamuna Power Limited has deployed a digital solution pilot project that predicts the energy demand at consumption points like electric vehicle charging stations and energy generation capacity at solar rooftops. This will help the utility plan to store excess energy by considering the distribution congestion and commercial aspects. 

Blockchain technology in renewable energy

The present system of the energy sector is centralized due to which the prosumer’s and consumers’ direct connection is yet to be formed. It’s due to persisting challenges like transaction efficiency, security and data transparency in the Indian energy market. The blockchain is a data-driven technology that helps create a very transparent process in data sharing among the peers involved in the system and sort out the challenges persisting in the energy market.

Forget batteries, what if surplus renewable energy could be stored as information?

A pair of researchers from UC San Diego has proposed to precompute certain data when the grid is flooded with solar or wind power, and then store it on servers for later use.

Record solar numbers expected this year but IEA highlights pricing concern

The Paris-based body expects the world will have installed almost 160 GW of solar this year, a record number, but still not enough to keep the prospect of a net zero global economy by mid century in sight.

ICRA improves energy demand outlook for FY2022

The ratings agency expects the energy demand in FY 2021-22 to grow by 8-8.5%. While the increased energy demand will improve the thermal plant load factor (PLF) level, this sector outlook remains negative as the PLF level will remain below 60%.

Proposed power market reforms could reduce renewable energy costs further

A new IEEFA note discusses the impact of the proposed market-based economic dispatch mechanism for procuring bulk power, and regulations for frequency control ancillary services.

Combining big floating solar with hydropower

Scientists in Bangladesh have evaluated how a 50 MW floating PV plant could be integrated with the 230 MW Karnafuli Hydroelectric Power Station, located at the Kaptai Dam on the Karnaphuli River. They found that the two energy sources can be perfectly optimized and that PV can compensate for the reservoir’s shortage of water storage during the winter season while hydropower can compensate for the poor yields of the floating array during the monsoon season.

The substantial sustainability benefits of smart meters

Power generated by renewable sources and corresponding action taken by business layers is not predictable. So it’s imperative that the latest controls are leveraged in the service of smart grids.

Hitachi ABB Power Grids commissions ultra-high-voltage DC link connecting Indian states 

The 1,800-kilometer link connecting Raigarh in Chhattisgarh to Pugalur in Tamil Nadu can deliver 6 GW. Power can be transmitted in either direction, depending on demand.

Earth sciences ministry revisiting weather forecast approach to suit solar sector needs

The Ministry of Earth Sciences will strengthen meteorological forecasting activities in sync with the demands of the solar and wind energy sector stakeholders. It is already working on a five-year (2021-26) plan, said M. Rajeevan, Secretary, MoES, at a virtual workshop conducted recently.
