2019’s grid storage additions fell for the first time since 2013. Why?

by

Globally, new installations of grid storage fell year-on-year in 2019 for the first time since 2013. This IEA summary of the landscape is taken from its latest series of Tracking Clean Energy Progress reports. The IEA’s recommendations reflect the fact that grid storage is new and complex, needing changes to existing regulations and market rules that are unviable in the age of transition. The policy goal is to monetise the value of storage in … [Read more...]

Energy Post panel discussion – Cross-Border Capacity [VIDEO]

by

Whilst renewable generation continues to grow, cross-border capacity fails to keep up. On May 19, 2020, Energy Post hosted a unique panel qualified to discuss the issue and shed some light on how we got here and what the options might be going forward. The discussion was moderated by Erik Rakhou - alternate member of the ACER board of appeal and consultant at Baringa. Representing the European Commission was Florian Ermacora and for independent, … [Read more...]

IEA: Battery storage races to keep up with solar and wind’s demand-matching challenges

by

Yesterday’s article from the IEA posed the question: will solar’s inherent intermittency slow its rise as a major power supply. For variable renewables like solar and wind to grow to over 50% of global capacity additions by 2040, storage technology must keep up with this pace. For this to happen, “flexibility” – the ability of the power system to quickly adapt to changes in power supply and demand – needs to grow by some 80% in the next decade … [Read more...]

IEA: solar’s exponential growth could make it less competitive, not more

by

Solar’s current growth trajectory means a doubling of annual deployment every three years. But despite further expected reductions in some cost areas (e.g. cheaper tech and economies of scale), the IEA’s new VALCOE (value-adjusted levelised costs of electricity) metric calculates that solar’s relative competitiveness per unit added will actually decline as its inherent demand-matching issues scale up with the growth. Brent Wanner, WEO Energy … [Read more...]
