Grids & Integration

Reactive Technologies uses an ultracapacitor to send signals to the grid that help managers determine the level of system inertia, supporting power grid stability – and they’re coming to the United States.

The Canadian provincial government’s Green Economy Plan, launched in November 2020, envisages a 37.5% reduction in greenhouse gas emissions en route to net zero by mid century.

Singapore-based Sun Cable has submitted its Environmental Impact Statement to the Northern Territory Environment Protection Authority. The document reveals the full extent of the project’s enormity, specifically a 17-20 GW solar farm tied to 36-42 GWh of battery energy storage, which is set to be transmitted by subsea cables to Singapore.

Developed by scientists in Spain, the new methodology is claimed to be capable of mitigating energy crises in Europe through climate predictions.

With each of the 10-year network development plans produced by Europe’s electricity transmission system operators years in the making, the latest such publication may already be out of date as the bloc prepares to fast forward its energy security and climate change ambitions.

The Spanish authorities applied solar curtailment for the first time on Easter Sunday, when power generation exceeded demand and the wholesale electricity price went from €168.50 ($182)/MWh to just €3.70/MWh.

The National Renewable Energy Laboratory’s (NREL) final report on the future of storage presents “key learnings” from a series of six in-depth studies.

To speed the interconnection of utility scale solar and storage, “maybe we want somebody running the show that has more of an interest in getting all these resources in the grid,” said law professor Shelley Welton in a webinar for “100% clean energy states.”

Researchers in Mexico have looked at integrating hydrogen-based power-to-gas-to-power into an existing rural microgrid. They said this solution could become competitive if electrolyzer, fuel cell and hydrogen tank costs are halved, or if diesel prices keep rising.

The International Renewable Energy Agency’s latest global outlook has spelled out just how ‘woefully’ far the world is from capping temperature rises at 1.5C, and lamented: ‘The stimulus and recovery efforts associated with the pandemic have also proved a missed opportunity.’
