The current market fails to generate pricing signals allowing full cost recovery of power generation. The European Commission decided to introduce a set of measures to ensure generation adequacy and supply security. The measures are further detailed in network codes, explains Jan Ondřich.
After surpassing 80 percent renewable electricity for a few hours last year, Germany may have briefly reached around 95 percent on May 8. But the news is not only cause for celebration – a boundary has also been crossed. We are now entering the hard territory. Craig Morris explains.
The Greek energy system is still relaying to a large extent on lignite power plants. Apart from the known negative impacts on public health, an increasing number of proposed projects will have a negative return on investment. Tasos Krommydas reports.
Renewable energy could supply Russia and Central Asian countries with all the electricity they need by 2030 − while cutting costs significantly. Paul Brown and Komila Nabiyeva investigate.
A recent editorial at Reuters charged that German nuclear policy is uncoordinated, particularly because the cost of nuclear waste disposal is still unclear. In reality, Merkel’s 2011 phase-out was a return to a former plan only briefly abandoned. And Germany’s phase-out budget looks pretty good internationally. Craig Morris explains.
The Poles have limited power imports from Germany in order to reduce “loop flows” through the country. Now, grid experts at the European Network of Transmission System Operators (Entso-e) warn that the country may no longer have generation and power import capacity to meet demand. By Craig Morris.
Germany’s Fraunhofer Institute for Solar Energy Systems (ISE) has added a new section on power trading to its Energy Charts website. Craig Morris says it dispels the myth that Germany is dumping excess renewable electricity on neighboring countries at low prices.
According to conventional wisdom, renewable energy needs storage options. While it is true that a completely renewable energy system would need mechanisms to balance supply and demand, there is surprisingly little need for energy storage until renewables reach a really high share in the power mix. Martin Tampier reviews the scientific literature and looks at the implications for North America.
The Swiss and Danish electricity sectors have quite a bit in common. Both are flooded with electricity from all sides. Yet, their power mixes are very different. The Danes have mainly wind and coal; the Swiss, primarily nuclear and hydro. The power lines were mainly built for coal and nuclear. Craig Morris takes a look.
In August, the fifth of five nuclear plants in Switzerland went off-line, but only for two days. There were no blackouts. Craig Morris investigates.
