AEMER, RSA España and FuturENERGY have published the English language version of the Guide entitled Recommendations for Periodic Diagnosis and Assessment of Wind Farms. The Guide represents a further step in the Association’s strategy for the internationalisation of maintenance providers, within its basic lines of action, which focus on professionalisation and quality.

The Guide addresses the main components of wind turbines: blades, tower, foundations, electrical equipment, mechanical transmission and substations. It also identifies the responsibilities of the different parties involved: owners, manufacturers, independent service providers and insurance companies.

The Guide fills a gap in the world of wind power know-how, given that there are scarcely any documents of Spanish origin published in English that can be of general use in the sector, in a context of foreign competition, mainly from Denmark, Germany and the United States.

This Guide is aimed at wind farm owners, insurance companies and maintenance companies, but it is also very useful for centres that provide training in accordance with GWO standards, as well as other complementary courses for the purpose of improving knowledge of equipment and components. This is particularly true in the current market, where older farms co-exist with more modern facilities featuring large wind turbines.

The ultimate aim is to optimise the performance of wind farms, accompanying them throughout their service lives at the lowest possible cost, whilst maintaining the highest standards of health and safety at all times.

GES has returned to the construction and installation activity in Egypt recently. In the last year, GES has been awarded with three new projects in the country. GES has a long experience in the O&M field in Egypt. The company has 200 MW in maintenance in the country and will add 40 MW more in the near future.

The instability and the special market situation forced GES to slow down its construction activity during the past years. But in 2016 GES took the opportunity to get back to work in the country, undertaking part of the electrical works and the installation of a 220MW wind farm.


A stable presence in Egypt made it possible to GES to commit the installation of such a huge project, integrating local workforce at the same time. This decision has been consolidated during the last few weeks, by the awarding of a new 20 wind turbines project, GES is already working on.

Egypt is a big market, where GES expects to grow in the near future. Carlos Charray, EMEA Sales Director mentions: “GES has a 300MW background in construction and installation in the Egypt. The company plans to keep growing in this strategic country.”

Siemens has completed extensive service operations on the gas turbines at Jebel Ali K-station in a record time of only 29 working days, a notable accomplishment for a project of this scale. The power plant is located in Dubai and owned by Dubai Electricity and Water Authority (DEWA) and in operation since 2002.

The outage featured the application of the “rotor-swap”; a pioneering concept that has been developed by DEWA to utilize a spare rotor and other critical parts, stored at the plant’s site, to maximize each unit’s availability and reduce idle time while waiting for the completion of rotor assembly work.


Under terms of the agreement, Siemens provided supervisory services for three of Jebel Ali K-station’s gas turbines to enable further efficient and reliable operation for approximately 100,000 hours – equivalent to about 15 years. The upgrades also increased power output by 62.6 MW and improved power plant efficiency by about 0.5 percent.

After a certain number of operating hours, all gas turbines need to be dismantled for maintenance services. Typically, an outage of this kind would take up to 45 working days to complete, involving over 100 personnel with different areas of technical expertise. By implementing a newer outage concept, Siemens was able to perform the services within just 29 working days, setting a new benchmark in the global power service industry.

Recently, Siemens and Dubai Electricity and Water Authority (DEWA) have signed an agreement to collaborate on an advanced data-driven project. Siemens and DEWA are working together to identify ways to improve thermal efficiency, provide cost-effective solutions for performance optimization, manage costs and reduce fuel consumption and emissions.

New research into turbine reliability from Wind Energy Update in partnership with Wind Energy Benchmarking Services (WEBS) has found DFIM turbines have the longest repair times per failure. The research took thousands of years of combined operational data for different generation capacities and turbine technologies. By measuring the time to failure and the repair time per failure, the research provides a cutting-edge insight into turbine reliability and performance. Participation in a benchmarking programme is critical to enable access to reliability and performance data, knowledge sharing of best practices and the implementation of sector-wide standards. This is already increasing investor confidence in the wind sector by reducing the levelised cost of energy. Without strong benchmarking capabilities, insights such as this are harder to detect and asset managers will miss out on the benefits of greater reliability and targeted maintenance planning, which benchmarking can offer.

The O&M landscape has undergone considerable changes in recent years. Owner, operators and IPPs are increasingly examining a range of O&M options as their assets reach end-of-warranty. A recent report by GCube noted that around 1/3 of all wind turbines are nearing the end of O&M service agreements. Operators, asset managers and those responsible for overall project operations are now assessing the value of independent service provider (ISP) maintenance contracts. Cost is often cited as an important issue when selecting an ISP or the OEM end-of-warranty package option. At a time of decreasing subsidies and record low auction prices, cost is increasingly significant, a trend expected to continue over the next 3-5 years.


Navigant Research has noted that warranties have now expired on over 50% of the global installed turbine capacity. Make Consulting predict that the global O&M market is set to grow from $9.7bn in 2015 to $19.3bn by 2021. This trend is particularly prevalent in the USA. IHS Energy Research forecast US O&M spending will almost double to $6bn by 2025 as a direct result of the number of turbines coming out of warranty. Read more…

Schneider Electric now offers one of the most comprehensive weather intelligence solutions in the market focused on the Wind Farm Operations and Maintenance segment

Schneider Electric recently announced the launch of Hub Height Wind forecasting capabilities within their WeatherSentryOnline platform. This feature helps identify potential risks of high wind speeds and wind gusts at turbine hub heights, and the impact they may have on assets. As a result, wind farms can do better maintenance scheduling and control maintenance costs, which can typically run into several thousand dollars per day.

Schneider Electric’s superior Hub Height Wind forecasting capabilities provide wind speeds, wind gusts and wind direction forecasts seven days in advance at different heights of turbines. Turbine-specific forecasts can be generated for any worldwide wind farm location.


Knowledge of forecasted wind activity will aid wind farm operators in scheduling proper times for maintenance—specifically, when high winds don’t pose a safety risk for maintenance equipment and personnel.

Improved operations planning saves money, avoiding costs such as crane rental fees, which have to be rented in advance. More efficient planning will help operators maximize output from the farm, as well as improve crew safety. High wind speeds can make maintenance work extremely dangerous, posing a threat to the safety of the maintenance crew. If the winds are forecasted to be high, the operator can modify the maintenance schedule for a clear period based on these forecasts.
