“California’s grid operator falls short during recent heat wave”

On Friday 14 Aug, an extremely hot and dry day in California and the west, California’s independent system operator (CAISO) had to resort to limited rolling blackouts that affected approximately 400,000 customers in California on Friday and the following Saturday 15 Aug.

Winter belongs to Wind Power

For weeks now, Germany and its European neighbors have had a peak season for wind power. The winter storms Sabine (also known as Ciara or Elsa), Victoria (known as Dennis in UK) and Yulia brought new records – most recently the unprecedented peak value of 46.2 gigawatts (GW). Renewables accounted for 69 percent of net electricity production in the third week of February, with wind accounting for 55 percent. Never before has so much wind power been fed into the German power grid. Are these figures the result of extreme weather conditions, which simply brought us an extraordinary number of storms this winter, or is there a general trend here? And how does the German energy system actually cope with these record values?

What is the Carbon Bubble?

What is the Carbon Bubble?Definition

The carbon bubble, also called CO2 bubble, is a theory that has its origin in climate and economic research. The term describes a possible overrating of companies that could only maintain their growth forecasts for the next few years by consuming fossil fuels on a scale that would violate the two-degree limit of the Copenhagen Treaty.

DERMS

What is DERMS?Definition

A distributed energy resources management system (DERMS) is a platform which helps mostly distribution system operators (DSO) manage their grids that are mainly based on distributed energy resources (DER). By lack of a common definition, a DERMS thus – depending on your point of view – is something similar or even identical with a Virtual Power Plant (VPP). 

On some key aspects, people seem to agree: DERMS is a software platform that is used to organize the operation of the aggregated DER within a power grid. The usual DERMS application is found at the distribution grid level. DERMS typically require a more full-fledged integration of various other systems such as a distribution management system (DSM) for integrating it with a utility. Furthermore, an outage management system (OMS) or a supervisory control and data acquisition (SCADA) system is usually needed to provide all DERMS functionality.

Dark city during a blackout period due to the weather phenomenon Dunkelflaute

Afraid of the dark

In the German language, there is a word that refers to the fear of having inadequate sunshine or wind to maintain a viable supply of renewable energy: dunkelflaute. The dramatic connotation of the word may be lost a bit in translation, but essentially, dunkelflaute means “a dark lull”.
