stantial share of our energy and in this way they are making a signifjcant contribution to protect our planet. they are the energy of the future. germany as one of the world’s most important industrial nations has decided to cover 100 % of its energy supply by renewable energies. the restructuring of energy supply is in full swing in germany. at the latest since the paris climate agreement in late 2015 energy generation from fossil fuels is no longer an option even on a world- wide scale. the same applies to the use of nuclear energy: it fails due to its high costs and risks. the rapid growth of renewable energies requires a professionaliza- tion along the entire value-added chain. Qualifjed specialists are the order of the day. rapId development of wInd energy technology the development of modern wind energy began in the 1980s in germany. Meanwhile an international industrial sector has established itself which also includes such global players as siemens and general electric. today’s machines can generate 100 times as much electricity as the earliest wind turbines.

modern wInd turbInes requIre extensIve know-how as performance increased the demands on man and technology also rose. today the control, monitoring and maintenance of wind turbines require extensive know- how both in the area of mechanical and electrical engineering, a lot of experience and appropriate tools. in view of the high performance of modern renewable-energy power plants malfunctioning results in substantial fjnancial losses. hIgh performance large-scale solar farms even in the photovoltaics segment today’s plants can in terms of dimension and design hardly be compared to those in the 1990s when the fjrst solar plants with just a few kilowatt output were built in germany. today, both rooftop and ground-mounted plants are built in megawatt size. some ground-mounted solar farms even reach an
the electricity yield of a single solar park is correspondingly large – and also the fjnancial loss if inverters or module strings break down. although on the whole solar farms are less service intensive than wind farms they also require continuous performance monitoring. today wind and solar farms are important, and in future they will be the decisive power plants for the energy supply. thus, their operation increasingly requires professional management.

the investor operates a wind farm with 8 wind turbines in northern germany. the plant monitoring is done by dge.
OUR APPROACh
the permanent monitoring of the farm discloses a continuously poor performance. the plant manager advocates for a replacement of the machine heads and wins
RESULT
the plant manager negotiates again with the manufacturer, to the effect that costs for the full maintenance contract are waived for 5 years. for this time period the reduction amounts to about 40 per cent of the annual operating costs. as a manufacturer-independent service provider with approximately 20 years of inter- national experience our know-how is extensive and we have a far-reaching network of

inspections and eXpert assessMents // windwerk – independent wind and solar farM services 20 | 21
wInd turbInes are subject to extreme strain. weather effects can cause
massive damage which may impede, or even preclude, operation. technical inspections help to obtain clarity on the current status of the turbine, iden- tify defects as early as possible, and as a result avoid costly consequential damage. this minimizes the maintenance effort, ensures a long service life of the machinery, and improves availability
OUR OFFER
as independent experts we will assist and advise you across the whole of the life- cycle of wind power plants.

Important for the successful construction, operation and
purchase or sale of wind farms are fair contractual regulations. contracts are often complex due to manifold technical descriptions and may be designed one-sidedly to the detriment of the operator, a factor which can then put him at a fjnancial disadvantage. the knowledge and implementation of appropriate regulations in your contracts by our legal and technical experts give you security.

bACkgROUND
the manufacturer sells a performance upgrade to a wind farm with 18 wind turbines which supposedly improves the power curve of the existing power. the manufacturer guarantees a yield increase of fjve per cent. the technical consultancy is taken over by dge.
OUR APPROACh
in order to verify the effectiveness the entire wind farm is equipped with the upgrade with the exception of two turbines. the operator commissions an accompanying analy- sis of the yield data of the plants with and without upgrade. the comparison shows that the upgrade measures of the manufacturer did not lead to any yield increase whatso-
fjnd a business solution that is attractive for the operator.
RESULT
thanks to the renegotiations better price terms could be reached for the full mainte- nance contract which could in addition be concluded over a longer time period. the savings amount to approximately fjfteen per cent of the overall costs for servicing and maintenance to be expected for the term of the contract.
