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
As a leading international network of expertise, IEA PVPS has the mission to cooperate on a global level in this rapidly evolving technology area.Read full article
The IEA Photovoltaic Power Systems Programme (IEA-PVPS) is one of the collaborative R & D agreements established within the IEA and, since 1993, its participants have been conducting a variety of joint projects in the applications of photovoltaic conversion of solar energy into electricity.Read full article

The present study provides background information about the European non-residential building stock, to be used for the assessment of the market potential of building energy technologies.
This paper investigates the energy efficiency aspects in the network design and operation based on the Energy Efficiency Directive (2012/27/EU) and its provisions related to network tariffs and regulation.
The analysis on the possible technical efficiency measures to reduce losses (chapter 2), shows that a variety of both equipment replacement and operational improvements can lead to greater efficiency.Read full article
The conductivity of copper is a factor of 5 less during fire. However, this is not taken into account in the current fire safety standards for cables. Consequently, a simulation case study was carried out on safety cables during a fire based on the design data of an actual large building—the GaleriaTarnovia shopping mall in Tarnow, Poland—in order to investigate cables’ properties in this situation and ensure future cable effectiveness.

Proper methodology for cable selection and sizing provides solution
Safety equipment and safety circuits in commercial buildings are likely to stop functioning in the event of a fire, even if they are designed and installed according to state-of-the-art methods and current regulations. This is due to the increased resistance at the temperature at which these circuits are required to function, according to the findings of a case study of a modern shopping mall in Tarnovia, Poland.Read full article
Africa is witnessing a trente glorieuses. Nonetheless, high oil prices coupled with global warming concerns have necessitated the development of renewable energy throughout Africa. Much of Africa understands these concerns, but incentive structures should be set so that states continue to diversify their energy supply.Read full article
After several years of the PV market’s rapid growth, 2012 has been a year of market consolidation. In total, about 28.4 GW of PV capacity were installed in the IEA PVPS countries and the major other markets during 2012 (2011: 28.9 GW; 2010: 16.7 GW). This raised the total installed capacity in IEA PVPS countries close to 89.5 GW with another estimated 7 GW of capacity installed in other major countries. Read full article
