Initial situation

After successfully operating its own Börger-Breddenberg wind farm consisting of seven E-66/18.70 turbines in 2002/3, ENOVA began in 2013 to work on a southern extension in the municipality of Börger.

Challenge

In 2014, the district of Emsland decided to revise its Regional Spatial Development Plan (RROP) in the wind sub-category in order to designate new areas suitable for wind. ENOVA countered opposition from quarters such as aviation and nature conservation and developed strategies to have the planned area included in the RROP. Finally, in 2016, after numerous discussions with the authorities and municipalities, ENOVA managed to have the area included in the RROP. Half of the project was also offered to the landowners for their own use. Every resident was also allowed to participate in the project through a fixed-interest loan. In total, €400,000 of the wind farm was partially financed by citizen investments to bring fresh wind for a greener future.

Result

The Börger Ohe 1 wind farm, which was commissioned in 2016 in the Samtgemeinde of Sögel (Emsland), consists of four Enercon E-115 wind turbines and has a total installed capacity of 12 MW.

Taking just under nine months to build, the wind farm was commissioned in June 2016. Its projected energy yield is around 31 GWh/a, which is equivalent to the energy demand of 9,000 households.

Wind farm and task description

Asset manager EB-SIM purchased a portfolio of Enercon wind turbines from Enercon on behalf of the investors in its Enercon Wind Onshore Deutschland fund, which spans several German federal states. They needed a wind farm manager for this portfolio to undertake technical asset management by providing in an “all-round, carefree package”. ENOVA stepped in in 2020.

Challenge

This all-round, carefree package is designed to offer the client a product that optimises operations, fulfils all of the requirements and automatically generates the comprehensive reports required by banks and the fund.

The portfolio encompasses various farms that present different challenges. Some of the turbines have been hived off from larger farms, others are subject to manifold official requirements or geographical peculiarities.

Solution

Our powerful, innovative e.live software enables the turbines to be monitored automatically, despite extensive parameters. Straightforward solutions and processes were established that meet every customer and official requirement, thanks to high-level staff expertise and flexible reporting.

Result

By using e.live it was possible to integrate monthly reporting which includes the following aspects:

  • Overview of the entire portfolio
  • Yield and revenue forecasts for infeed and curtailment including Section 51
  • Consideration of different financial models
  • Detailed TARGET/ACTUAL comparisons of different loss groups
  • Evaluation of service response times

Evaluations of bat and mast shutdowns in communication with authorities, and direct marketing and redispatch work (including custom solutions), were also optimised using structured processes, and wind farm shutdowns were reduced through the coordinated deployment of wind farm wardens.

Wind farm and task description

The Uetze wind farm consists of six Vestas V 112 wind turbines which were commissioned in 2017. Once ENOVA IPP had purchased the wind turbines, technical wind farm management was taken over by ENOVA.

Challenge

The turbines at Uetze are equipped with a bat shutdown system to meet permit requirements. A set of parameters had been determined on the basis of expert biological opinions which predict the likelihood of bats, and the turbines shuts down under such conditions to protect them. Once the turbines had been included in our technical operation management and past operating data had been evaluated using ENOVA’s own e.live software, it became apparent that bat shutdowns had been happening wrongly for a long period of time and that significant yield losses had been caused by unnecessary shutdowns.

Solution

Specific data was evaluated in e.live to clearly demonstrate a technical defect, which revealed the resulting yield losses and the technical availability freed up by eliminating incorrect shutdowns.

Result

By proving the losses and negotiating hard over the loss of income, we secured a refund of lost profits and adjusted the service contract to align with energetic availability.

Wind farm and task description

The Waldfeucht wind farm has 14 Enercon E-66 18.70 turbines and was commissioned in 2004 in the district of Heinsberg (North Rhine-Westphalia). It has a total output of 25.2 MW.

Following its purchase in 2021 by ENOVA Value, the wind turbines are to be replaced by seven Nordex N-163 turbines in cooperation with local partners the Frauenrath Group and BMR energy solutions GmbH, to produce a total output of 39.9 MW.

Until repowering takes place, the turbines will be operated using all the capabilities of the ENOVA group in alliance with external partners.

Challenge

After acquiring the old wind farm from its Danish owners, we had to obtain approval for repowering as quickly as possible while continuing to operate the old farm cost-effectively.

By taking over the wind farm’s technical and commercial management, ENOVA was able to optimise its monitoring and liquidity planning. ENOVA Service was also able to introduce a cost-optimised partial maintenance concept which substantially reduced costs during the operating period.

Cash flow from the old farm paid for repowering, which was done together with partners BMR energy solutions and Frauenrath.

Solution

ENOVA is responsible for structuring financing and general stakeholder management, BMR/Frauenrath for on-site project development. By combining their expertise it was possible to obtain approval for seven turbines and their acceptance in the EEG tender within two years of purchase.

Result

By combining the capabilities of the ENOVA group, it was not only possible to ensure continued operation until repowering, but also to complete all of the preparations and measures needed for repowering in collaboration with the partners.

When the external operator became insolvent, ENOVA managed to take over all of its responsibilities within just a few days and ensure continued economic operation in close alliance with ENOVA Service GmbH. The activities involved in operational management and the provision of services are coordinated so as to avoid unnecessary costs caused by the upcoming repowering. This in turn will achieve the best possible economic outcome for the period until repowering.

Working with local project developers, ENOVA was able to demonstrate not only its competence, but also its ability to work in a team and adapt flexibly to different structures

Wind farm and task description

The Hohegaste wind farm, which was repowered in 2017, consists of four Enercon E-101 wind turbines. Installed in Leer in East Frisia, they have a total output of 12.2 MW. The wind farm was taken over by ENOVA IPP in collaboration with Oldenburg-based EWE Erneuerbare Energien GmbH (now operating under the name Alterric GmbH). Each company acquired 50% of the wind farm.

Challenge

The Hohegaste wind farm was sold by 27 limited partners who had operated it for more than 20 years, initially with 14 Enercon E40s and then, following repowering in 2017, with new turbines. Many of the partners wanted a one-off sale, rather than receiving returns from repowering over 20 years. But because of the complex limited partner structure, it was not entirely easy to satisfy everyone.

Solution

EWE and ENOVA were able to convince the former operators with a joint offer. It provided for a one-off sale sum and guarantees that the sellers could easily calculate, with no further risks from the operation and remaining construction of the turbines.

Result

EWE and ENOVA’s joint offer convinced the sellers and they handed over the project in summer 2018.

Wind farm description

With its 70 Enercon E-40 5.40 wind turbines, Midlum wind farm, which began operation in 1999, is one of the largest in Europe. A total capacity of 35 MW is installed across the facility.

Challenge

Because the wind farm cannot be repowered, a suitable concept had to be developed in order for it to operate economically, even at a lower energy tariff.

Solution

ENOVA Service GmbH’s aim was to develop a concept that would ensure continued long-term economic operation. By analysing the wind farm’s last 20 years of operation, we identified the biggest cost drivers among the spare parts and derived ways of obtaining them cost-effectively. We also had to secure against large component damage. By purchasing and reconditioning several identical Enercon E-40 5.40 wind turbines, it was also possible to minimise the risk of economic decommissioning caused by damage to major components.

A stock range target of one year was set in order to ensure that spare parts would be rapidly available. This target can be tracked in real time using our ERP system and automatically adjusted to the number of wind turbines under management. This system enables us to respond quickly to changes in the market, in order to ensure continued economic operation.

Result

These activities led to the development of a continued operation concept for Enercon EP1 platform (E-40 to E-53) turbines, which not only ensured ongoing economic operation at the Midlum wind farm, but also allowed other operators to benefit from synergies in the future.
