The development of Electrical Energy Storage technology (EES) carries the weight of huge expectations. According to an earlier International Electrotechnical Commission White Paper, many of the medium and long-term renewable energy targets that have been set by governments are impossible to achieve without a fundamental breakthrough in storage technology. Energy storage systems already exist, but a major technology shift is required to enable large-scale deployment.Read full article
PV Grid Parity is defined as the moment when PV Levelized Cost of Energy becomes competitive with retail electricity prices, assuming that 100% of the electricity is self-consumed instantaneously. This point has already been reached in many regions of the world.Read full article
The stresses responsible for transformer failures, creep behavior of aluminum conductor, operating conditions, frequent magnetic inrush current and their effects on the life of distribution transformer (DTs) are being investigated. It is being investigated by conducting experiments that hot spot temperature, creep behavior of aluminum conductor, and frequent switching of DTs in the field may be responsible for excessive failures.Read full article
Denmark is seen as the great wind power success story. But the number of ordinary Danes participating in the wind power sector actually decreased for many years.
In 2004, 100,000 Danish households owned shares in community wind power projects. 3,000 MW of wind turbines was installed by 2003 – double the target set by the Danish government for 2005.Read full article
All power transformers have very high energy efficiency—the largest are probably the most efficient machines ever devised. However, there is still scope for improvement. Any improvement in the performance of large transformers offers the potential of genuine economic benefits because their throughput and their continuous duty mean that the energy they waste is likewise enormous.Read full article

Summary : The energy performance of buildings is key for reaching the European Union’s very ambitious climate targets. “Nearly zero energy building (nZEB)” is the term for a building standard that complies with this ambition.
Living in 2013 we have 8 years to go until every single Member State will have to build every new building as nearly zero energy building, and even only 6 years to go for nearly zero energy public buildings.Read full article
The increasing deployment of intermittent resources, decentralised generation, and the expectation of further electrification pose a number of challenges to DSOs and TSOs in relation to the balance of supply and demand. The increasing interest in demand reduction and demand shifting has resulted in discussions about how dynamic pricing can be used to best encourage household end-users to change their energy behaviours - more specifically to shift (and reduce) energy consumption.Read full article
Industrial companies seeking ways to reduce energy consumption often call upon external advisors to assess the energy efficiency of a plant. While this is generally a good idea, it is unwise to leave this task entirely up to the external advisor. Identification of promising opportunities for saving energy requires thorough insight into the plant’s processes and a profound knowledge of the process design. Plant engineers and operators generally have a much greater insight into their plant than external advisors.Read full article
