ENOVA Wind Farm Management expands its offer in the fields of CMS (Condition Monitoring System) for gearless wind turbines

/in /by

Since autumn 2019 ENOVA Wind Farm Management is offering vibration analyses within the scope of condition monitoring. In the course of expiring full maintenance contracts and continued operation of old wind power plants for more than 20 years, the early detection of major damages is an elemantary issue.

“Especially on rolling bearings of gearless wind turbines, harmful influences should be detected before they lead to damages. This enables us to have repairs carried out by the full maintenance contractor before the full maintenance contract ends. This prevents cost-intensive consequential damages and the associated plant failures”, says Technical Wind Farm Manager Ralf Brinkema. The vibration analysis is an essential component in the overall evaluation of a possible further operation of old plants which is superviced by the ENOVA Wind Farm Management. The results allow actuarial questions to be answered and give an estimate of the further operating time. That knowledge is an effective protection against expensive bad investments.

Successful year for the ENOVA Group

/in /by

Bunderhee, 18.12.2018. The East Frisian ENOVA Group can look back on a financial successful year 2018. For example, the wind energy specialist has acquired stakes in onshore and offshore wind farms with a total output of 70 megawatts via the network company ENOVA IPP. In August 2018, ENOVA IPP and EWE ERNEUERBARE ENERGIEN GmbH, took over the 12-MW Windpark Hohegaste. EWE and ENOVA share the technical and commercial tasks in the operation of the wind farm.

Project successes in repowering and technical operation management

After a successful repowering in January 2018, ENOVA Energiesysteme commissioned the WPP Sanden in Ostfriesland. From mid-March to October, the repowering and scheduled commissioning of the Düddingen wind farm took place, which has a 50 percent higher output now. “In addition, we are steadily expanding our portfolio of wind farms, where we provide services related to asset management, such as technical operations management,” elaborates Managing Director Hauke ​​Brümmer. In 2018, ENOVA took over 43 EWE WPP. The total portfolio of managed WPP comprise more than 250 megawatts. The technical management will offer further services such as Big Data evaluations and condition monitoring solutions in 2019.

Manufacturer-independent service provider maintains more than 50 wind turbines.

At the turn of the year ENOVA Service, founded in 2017, will handle a portfolio of 100 megawatts. In the second half of 2018, the manufacturer-independent service provider started maintaining 16 further wind turbines. In July 2018, the complex rectification of a major component damage was achieved: during the repair of a defective powertrain, the service specialists first exchanged only the main bearings and repaired the defective axle journal without replacing the entire hub.

Wind farm Dueddingen put into operation

/in /by

The time has come: The Dueddingen wind farm will be connected to the grid after a successful repowering within the tight schedule! In mid-March 2018, the first construction measures began in the area of ​​the Wesermarsch. Approx. eight months later, the four new Enercon E-70 E4 wind turbines, each with a capacity of 2.3 MW, were completed and commissioned. The old NEG Micon 1500-64 from 2000 was dismantled and replaced by the new ones.

David Szilagyi, Project Developer at ENOVA, said: “We made it! And the whole thing according to plan. Despite some adversities, the project was implemented very well thanks to the dry summer and the well-rehearsed performance of all project participants and subcontractors.” The project schedule was particularly stringent with the tight schedule and the necessary extensive coordination between the trades. During the dismantling of the old plants were still in full swing, the new wind turbines were already being built elsewhere. Another obstacle was the current situation of access via a private railroad crossing, which made larger transport difficult. However, this hurdle was taken sovereign.

The new plants reach with a hub height of 64 meters and a rotor diameter of 71 meters a total height of about 100 meters. They will produce over 15,142,000 kWh of electricity annually. This is enough to supply just under 4,000 households with renewable energy, resulting in CO2 savings of around 9,000 tones.

Successful fair presentation at the WindEnergy Hamburg 2018

/in /by

Once again ENOVA was represented at the WindEnergy fair in Hamburg, Germany. The fair offered the perfect platform for a constructive exchange and very interesting discussions across all business areas – new partner- and customer relationships are in sight.

Especially for the affiliated company, ENOVA Service, the appearance was a complete success. Many potential customers found their way to the independent maintenance company for gearless wind turbines. Managing Director Dietmar Buß is confirmed in his strategic direction by the hustle and bustle at the ENOVA fair stand: “Many operators are looking for a service alternative, for being able to economically realize the continued operation of their wind turbines after the expiration of the EEG compensation. Together with my colleagues, we’ve been able to introduce our maintenance concepts to many interested parties and see, among other things, the Windenergy offers a short-term growth potential for our services of over 200 MW.”

The highlight of the event was the ENOVA Service trade fair party on Thursday evening. The reason for this, in addition to the service provider’s one-year existence, was also the first settlement of a major component damage as an independent service provider on an Enercon wind turbine. With lager beer, snacks and good music, the numerous guests could end the day of the fair.

Many thanks for the technically demanding exchange and the numerous visits – we are already looking forward to the next fair!

Start of the repowering of the wind park Düddingen

/in /by

Here we go!: The first construction work of the wind farm Düddingen in the district of Wesermarsch began on schedule in mid-march. The four older NEG Micon NM 1500-64 wind turbines from 2000 will be repowered by four new Enercon E-70 E4 wind turbines, each with a power output of 2.3 MW. The expected commissioning of the new plants is scheduled for the third quarter of 2018.

With a hub height of 64 meters and a rotor diameter of 71 meters, the new wind turbines reach a total height of approx. 100 meters. They will produce more than 15,142,000 kWh of electricity per year. This is enough to supply just under 4000 households with renewable energy and save 9000 tons of CO2.

Commissioning WPP Sanden

/in /by

On time and kept to the budget the repowering action of the windmill-powered plant Sanden finished after five months of construction in January of this year. The old engine, a Vestas V-66, got replaced by a new Enercon E-92.

By repowering the annual energy output has nearly doubled. With a hub height of 85 m and a rotor diameter of 92 m the wind turbine generates an energy amount of approx 4.7 GWh/a. This supplies the energy requirement of more than 1100 households.
The repowered wind turbine is located in the industrial area of Weener in Ostfriesland.

ENOVA takes over the technical management of 43 wind turbines from the EWE portfolio

/in /by

At the beginning of 2018 ENOVA took over the technical management of 71 MW of the portfolio of the EWE AG. In the tender ENOVA prevailed against a large number of competitors. “We are very pleased. Being able to use our know-how to increase the performance of the EWE portfolio is great,” says Ralf Brinkema, Head of Technical Operations Management.
The wind farms will be transferred in two stages. By January 2018, 44 MW will be taken over by ENOVA, followed by another 27 MW in July 2018. The portfolio contains among others 1x ENERCON E112 with 4.5 MW, 1x E112 with 6 MW and 1x E126 with 7.58 MW.
About one year ago, ENOVA reorganized its operations management. Over the year, 19 wind turbines with a total capacity of 60 MW have already been added to the portfolio.
The acquisition of the EWE portfolio now underlines the successful realignment. Just in time for the turn of the year, ENOVA’s management breaks the 250 MW barrier.
The special features of the ENOVA management are e.g. the use of independent monitoring software, the absorption of operator obligations, short reaction times and the theoretical as well as the practical skills of the employees. In particular, the practical experience of the technicians on ENERCON wind turbines ensures a balanced relationship between operator and manufacturer/ service provider.

Since early 2017, ENOVA’s smart wind farm management offers a lean management with a focus on yield optimization, lifetime extension and compliance. Also worth highlighting is the need-based compilation of ENOVA service packages and modules: a small, smart package that only contains services that are necessary for a maximum energy output.
A “save package” that secures the operator and in which services in the area of occupational safety or plant inspections are taken over. Last but not least there are various extra modules that help the costumer to simplify the operation of the wind farm when needed, to better evaluate the performance and to make better decisions. Brinkema: “With these service packages, we can map every individual customer request at attractive conditions.”

At the end of the year at least another 11 wind turbines will be taken over by ENOVA Service.

The services range from remote monitoring through maintenance and inspection to corrective repair.

The concept is characterized by a quick troubleshooting, a cost-oriented pricing in the corrective repair, a transparent and rapid flow of information and the usual security of a manufacturer’s concept.

Desire for wind: wind park festival thrilled numerous visitors

/in /by

On the 1st of September, six companies involved in the wind farm party of Börger had invited to their Windparkfest. (ENOVA Energieanlagen GmbH, ENOVA Windpark Börger Ohe 1 GmbH & Co. KG and ENOVA Windpark Börger Ohe 2 GmbH & Co. KG, as well as the energy parks Ohe GmbH & Co. KG, Ohe II GmbH & Co. KG, Sievers Energy GmbH & Co. KG and Ohe GmbH & Co. KG, which are mainly operated by citizen participations). The occasion was the ceremonial opening of the Börger Ohe 1 and 2 wind farms to the public, in which a total of eleven wind turbines will generate around 87,000 MWh of renewable energie each year.

Project participants, regional politicians and public officials as well as property owners gladly accepted the invitation. 

The whole topic of wind energy where praised by Jürgen Ermes, mayor of Börger, as well as Ulrich Janzen, board member of Volksbank Nord, Frauke Reimers of Enercon and Wilhelm Pieper, chairman of the BWE Niedersachsen in their short speeches. The detailed thanks of ENOVA, expressed by Managing Director Helmuth H. Brümmer, was shared by all those involved in the project, specifically the district, the municipality, the landowners, the manufacturers and suppliers and its employees: “Thanks to the commitment of each individual, many kWh of clean energy are generated” said the company founder, who is currently launching another company with ENOVA Service GmbH. The independent wind turbine service provider started operating the same day. CEO Dirk Warnecke: “We have successfully resolved the first disruption, and we are glad that the energy is flowing again.”
And as befits a proper celebration, the appropriate entertainment was not missing: a desire for wind was created by a view gondola, which granted a view over the whole wind farms Börger, Börger Ohe 1 and 2 as well as Breddenberg Ohe and the opportunity to visit a wind turbine. Children were able to let off steam on the specially constructed bouncy castle and of course the physical well-being of all guests where taken care of in the large marquee.


To the project:
Since 1999, ENOVA has been active in Börger together with the municipality and acts as general contractor of all wind farms located there. In 2002, the old wind farm Börger was built, which has generated about 245,000MWh regenerative energy since then. In June 2016, the wind farm Börger Ohe 1 with four ENERCON E-115 / 3.0 MW wind turbines was put into operation. Just one year later, the commissioning of Börger Ohe 2 with seven ENERCON E-115 / 3.2 MW. Due to the new and old wind farms, the municipality of Börger contributes decisively to the energy turnaround: Annually a total of about 105,000 MWh of clean electricity is produced. The technical and commercial management of all parks is carried out by ENOVA.
