  • Rubrik: Datum: Title: Servicing is feeling the cost pressures

    Increasing demands by the operators of wind turbines on service and maintenance providers, as well as growing cost pressures, are topics which the sector must look at. This is a conclusion from our current survey of wind power service and maintenance companies.

  • Rubrik: Datum: Title: PV Inverters: Activities which catch the eye

    Inverters have become mass-produced standard products. If a manufacturer wants to stand out it must either offer a superb product or take an entirely different approach.

  • Rubrik: Datum: Title: How can you get the best value out of your energy storage?

    A key challenge for renewable energy plant and utility operators is the selection of the optimum size of lithium-ion (Li-ion) energy storage system to deliver maximum operational and financial benefit. This is because an ESS can have several different roles: control of ramp rates; power smoothing; power shaping/shifting; peak shaving; frequency regulation. Only by understanding its required role and the specifics of each site can we can specify the right ESS for the job.

  • Rubrik: Datum: Title: Upgrades: Optimisation during ongoing operation

    It takes an average of two years of work to bring a new wind turbine onto the market. This is too little time to test each component in detail. But no problem: updates can improve the yields and cost structures of existing turbines.

  • Rubrik: Datum: Title: Premium modules: Players in the top league

    Premium modules are in the champions’ league when it comes to performance and reliability. SUN & WIND ENERGY has surveyed selected players in this top flight about their latest products – and their estimation of the market for these innovations.

  • Rubrik: Datum: Title: China Renewable Energy Outlook 2017

    China has started the transformation from a coal-based energy system with high environmental costs to a low-carbon and environmentally friendly energy system. Our analyses show that the right strategy for policy measures are on the table, but the success of the energy transition depends on strong practical use of these strategies – the power market must be enforced in a way that stimulate flexibility and integration of RE, the carbon pricing mechanisms must ensure sufficiently high carbon prices to make an impact on CO2 emission and the support schemes for RE must stimulate costefficient deployment of RE projects. Also, more ambitious targets for RE and for coal reduction are needed in the short run if China shall be able to comply with the Paris agreements requirements for a “well Below 2 °C” future.

  • Rubrik: Datum: Title: High renewable future in the UK and Germany to create new power systems flexibility challenge

    Economic tipping points mean renewable energy will account for over half of electricity generation by the mid-2020s in the UK and Germany. This comes as the cost of generating energy from wind and solar is expected to more than halve from today’s levels by 2040.

  • Rubrik: Datum: Title: Wind Turbines: An eye on the technical management

    The technical management is responsible for the smooth technical operation of a wind farm. As the tasks become more complex, however, the cost pressures rise as well.

  • Rubrik: Datum: Title: Off-grid systems: Solar energy replaces fossil fuels

    A mountain lodge, a remote part of the country or maybe a comfortable mobile home - sometimes it is difficult or even impossible to connect to the public electrical grid. Then, this is the time for off-grid systems capable of operating independently. The german company enerquinn Energiesystemtechnik GmbH is an experienced full service partner for off-grid systems. In addition to the individually optimized planning and concept design of off-grid PV systems, they also take care of installation, commissioning and training of the operators or their customers.

    Effective action on energy is essential to tackle climate change, according to a new landscape review of EU Action on Energy and Climate Change published by the European Court of Auditors. Energy production and use account for 79% of EU greenhouse gas emissions, say the auditors. Even if efforts to cut greenhouse gas emissions are successful, adapting to changes in the climate is necessary. By the end of the century, Europe’s climate will be significantly different even under the temperature increase of no more than 2°C envisaged by the 2015 Paris agreement.
