Challenged with the rising contribution of inherently intermittent wind and solar power supply, network operators are investing billions in stabilising their power grids. To anticipate supply/demand patterns and avoid overloaded grids, GreenCom Networks has developed an “Open-innovation Lab” with live data from end-customers. The system links electric cars, PV systems, heat pumps and other energy equipment in Germany and France.
Maritime Link, an ABB-built 500-megawatt power link between Canada and the US, has passed a key milestone in testing. The high-voltage direct current (HVDC) interconnector allows for renewable energy, generated in Newfoundland and Labrador to be transmitted to the North American grid in Nova Scotia.
Energy storage technologies like batteries create an “unusual combination of cost and revenue streams,” according to EIA analysts, given that they can serve as both energy suppliers and consumers at different times. Thanks to their versatile functionality, about 700 MW of new utility-scale batteries has been added to the US power grid over the past three years.
China’s leading power generation equipment manufacturer Harbin Electric has ordered two GE 9F.05 gas turbines for the State Power Investment Corp’s (SPIC) 800-MW Langfang gas combined-cycle power project. Harbin Electric itself will provide steam turbines, generators and other auxiliary systems for the CCGT, due for commission in 2019.
The Australian Prime Minister Malcolm Turnbull has made a political U-turn on energy, dismissing earlier instated 'clean energy targets' in favour of stipulating guarantees for reliable power supply and emissions reductions as the two new pillars of his new policy. Utilities will henceforth be obliged to deliver electricity at times of peak demand.
Intermittency issues of wind and solar power supply are feared to jeopardize the stability of the U.S. power grid. To remedy this issue scientist at the Massachusetts Institute of Technology (MIT) have developed an “air-breathing” battery storage that, at the cheapest, run about $100/kWh and functions only in certain locations.
Falling costs for renewables and energy storage will squeeze out gas-fired generation in South Australia as early as 2025, Wood Mackenzie and GTM Research find. By then, wind, solar and battery costs are seen decline by 15%, 25% and 50% respectively – hence they offer a “lower cost alternative” to CCGTs, which cover the bulk of South Australia’s base load power today.
Just days after launching a transformation plan, NRG Energy has disclosed it will divest 6 GW of conventional power generation capacity, and 50-100% of its renewable energy arm, NRG Yield. The American utility said it hoped to raise between $2.5 billion and $4 billion in cash proceeds from the sale. Mauricio Gutierrez, NRG president and CEO said underlined the board’s “commitment to simplify and strengthen the company to thrive through any market cycle.”
The Caribbean island of Aruba’s main electric utility, WEB Aruba, has awarded a contract to ABB to supply an advanced microgrid in order to help integrate solar and wind energy through production forecasting and real-time optimization of operations.
Los Angeles Department of Water and Power (LADWP), California’s largest public-owned utility, is reconsidering plans to spend over $2 billion on natural gas and power infrastructure. The company’s board confirmed it "has put on hold all planned local repowering projects until a system-wide, in-depth, and independent study/analysis is conducted." Falling costs for renewables, and rising green energy supply, has inspired the California Senate to propose a 100% renewable energy target by 2045.
