BImSchG for the Heerenweg repowering project

For the wind farm repowering project Heerenweg, in course of the approval planning, the approval decision in accordance with the Federal Immission Control Act (BImSchG) was granted by the district of Leer in September 2015.

On behalf of Windpark Heerenweg GmbH, ENOVA Energieanlagen GmbH has prepared the BImSchG application for the project “Repowering Heerenweg” (Bunde, Leer district) as part of a service contract. 6 WEA locations are planned with the manufacturer SENVION. As part of the approval planning process, ENOVA handles the preparation of the application as well as the interface communication between the district involved, the municipalities and the assessors. Furthermore, the coordination with clients by ENOVA as well as the participation in all government appointments including the application conference takes place.

The new 3.4M114 plants have a nominal output of 3.4 MW, a rotor diameter of 114 m and a hub height of around 93 meters. They replace the nine existing E-40 plants from Enercon with a rated output of around 500 kW. The construction of the access road and the crane shelves has already begun.

Furthermore, ENOVA is commissioned to implement the grid connection of the wind farm to the public electricity grid. Due to the higher capacity of the new wind farm, further use of the previous grid connection is not possible. The approx. 11 km long 30 kV underground cable system connects to the new substation (UW) on the 110 kV line of AVACON AG. As part of a service contract, ENOVA Energieanlagen GmbH is responsible, among other things, for the planning of the line, the negotiation of user contracts with landowners and the obtaining of permits. In addition, ENOVA coordinates the planning and construction work of third parties, such as electrical engineering, cable laying and the erection of the substation.

Wind energy conference NRW

From 26 to 27 November, the Wind Energy Days NRW offer operators, planners and project engineers of wind turbines a central exchange platform. Also this year ENOVA will be represented at the industry meeting as a sponsor and exhibitor. The event is organized by the NRW Regional Renewable Energy Council in cooperation with the North Rhine-Westphalian State Association of the German Wind Energy Association. Around 350 participants and over 35 exhibitors are expected.
The ENOVA Group is already planning and projecting several wind farm projects in North Rhine-Westphalia.

Thematic focal points of the wind energy days include the tendering procedure 2017 and its effects on wind energy inland as well as the design of future wind power marketing. In addition, the expansion of wind energy in North Rhine-Westphalia is discussed.

Approval for repowering project in industrial terrain

For the ENOVA planned repowering of a wind energy plant on the grounds of Klingele Papierwerke GmbH & Co. KG in Weener, East Frisia, this week the approval according to Federal Immission Control Act (BImSchG) was granted.

Since the end of 2013, ENOVA has been planning and implementing the repowering of a Nordex N52 wind turbine on the industrial site of the paper mills. With the premature building permit issued by the district of Leer it was already possible to start the preparatory work for the access road, the crane parking areas and the erection of the foundation at the end of April. The preliminary work on the foundation including the measures to improve the soil has already been completed. 

On the industrial site of Klingele Papierwerke GmbH & Co. KG, the old system with a hub height of 60 m and a rated output of 1000 kW will be replaced by a new, more powerful one. The E-101 from Enercon has a hub height of 135 meters and a nominal output of around 3 megawatts (MW) with a rotor diameter of 101 meters. Commissioning is planned for 2015.

Upon completion, the wind turbine will produce an annual energy yield of around 8.5 million kWh.


To the performance overview

Approval granted for project Neuss

ENOVA had already submitted the BImSchG application in the summer of 2014 for the realization of two wind turbines for Stadtwerke Neuss. For the wind farm project ENOVA was commissioned in May 2013 with the approval planning of two wind turbines. Now the final approval was granted for the wind farm project. The planned wind turbines have a nominal output of up to 2.3 MW, a rotor diameter of up to 82m and a total height of around 180m. At present, preparations are being made for the implementation of the access route and the cable route. The two wind turbines are to be built in the Neuss-Hoisten district and provide electrical energy for approximately 3,000 households in the region.

Financing for offshore wind farm “Nordsee One” is set

 On March 19, Northland Power Inc., Toronto (“Northland”) and RWE Innogy GmbH, Essen (“RWE”) announced the full placement of project financing for the planned North Sea One offshore project. An important milestone has been reached in the amount of 1.2 billion euro invested. Northland’s share of the offshore wind farm is 85 percent, with RWE holding the remaining 15 percent of the shares.

Northland and RWE are also joint owners of the North Sea 2 and North Sea 3 projects, which are still in the early stages of development. These projects (formerly Innogy Nordsee 1-3) have initiated the ENOVA group of companies and have taken over the approval planning. In 2008, the project rights of the offshore wind farms were sold to RWE Innogy GmbH. After the sale, the project area was divided into three segments of almost equal size. As a project developer, ENOVA continues to be entrusted with the development of all three wind farm areas until approval.

The project area for the planned offshore wind farm “Nordsee One” is located 40 kilometers north of the island of Juist in water depths of up to 29 meters. A total of 54 wind turbines of the 6 MW class are to be erected there. The construction of the offshore components is sheduled in 2016. Commercial operation is planned for the end of 2017. After commissioning, “Nordsee One” will supply around 400,000 German households with renewable electricity.

The North Sea 2 and 3 projects have a total output of 670 MW and will be developed over the next ten years.

Application for BImSchG approval for the wind farm projects in Weener, Neuss and Gemünden

ENOVA is planning nationwide projects in the field of onshore wind energy. For the current projects in Lower Saxony, North Rhine-Westphalia and Hesse, ENOVA brings in its many years of experience as a service provider.
ENOVA was commissioned by Klingel Papierwerk GmbH & Co. KG in Weener with the design and approval planning for the repowering of an existing 1MW wind energy plant. For this purpose, the application was submitted in August 2014 in accordance with the Federal Immission Control Act. The new 3 MW ENERCON E-101 wind turbine will replace a NORDEX N52 turbine. In addition to the supply to the public grid, there is the technical possibility of direct self-consumption in the connected Klingele Papierwerk.
For Stadtwerke Neuss, ENOVA is entrusted with the realization of two wind turbines of the multi-megawatt class. For this purpose, in the summer of 2014 the BImSchG application was submitted to the competent authority, for which the draft approval has meanwhile been submitted. A final version is expected shortly. The planned plants will supply electrical energy for about 3,000 households in the region.
The BImSchG approval is also currently expected for the project in Gemünden, upon receipt of which the construction phase will begin. The wind farm, consisting of eleven Nordex N117 wind turbines, with a capacity of 26.4 megawatts, is expected to go into operation in 2015. The client is the Verbands-Energie-Werk (VEW) Gesellschaft für Erneuerbare Energien mbH, which will also operate the wind farm. In the future, about 23,000 households should receive clean electricity from wind energy.

Windfarm Kaiserslautern: Plans are progressing

In Kaiserslautern, the ENOVA Group plans in cooperation with Thüga Erneuerbare Energien GmbH & Co. KG and SWK Stadtwerke Kaiserslautern Versorgungs-AG two wind turbines, each with a capacity of 3 megawatts. For this purpose, the company Stadtwerke Wind Kaiserslautern GmbH & Co. KG was founded in 2013, in which the cooperation partners each have a one-third share.
The development of the Kaiserslautern wind farm is progressing as planned. The permit application for the construction of a wind measuring tower was recently submitted. The wind measurement mast is used to measure the wind speed at various altitudes in m/s (meters per second) in order to estimate how much electric energy the plants will convert. The wind measurement is carried out for about one year and after completion of the measurement, the wind measuring mast is dismantled again.
According to previous results of the research on species protection, it is assumed that the wind farm can be operated without significant restrictions. “We see very good conditions and are confident that we will be able to finish the park in 2016,” says Dirk Warnecke, technical director at ENOVA and one of the managing directors of the operating company. The wind energy produced in the future is destined for the region and will supply approx. 4,400 households with green electricity.

Wind Energy Days NRW

On November 27th and 28th the Wind Energy Days NRW take place in Bad Driburg. The event is a central meeting place for operators, planners and project developers. ENOVA will also participate in the industry get-together and is a sponsor of the industry meeting point.
The ENOVA Group is currently active with several wind farm projects in North Rhine-Westphalia and is further expanding its involvement in the fourth largest federal state.
Against the background of the decision of the amendment to the Renewable Energy Sources Act (EEG) shortly before the summer break, planning and licensing issues at the state level are assumed on the wind energy days. Topics include the marketing of wind energy in the electricity market of the future, the financing of new projects under changed legal conditions as well as current legal issues of planning and approval practice in NRW.

Legal security for Riffgat Offshore Wind Farm

On Friday, October 24 the Foreign Minister of Germany, Frank-Walter Steinmeier (SPD), together with the Foreign Minister of the Netherlands, Bert Koenders, signed a treaty addressing the border in the Ems estuary area. The exact boundary line between the two countries has been unclear since the 15th century.

A new version of the Ems-Dollard Treaty, signed in 1960 “in the spirit of good neighborliness”, had become necessary as the construction of Riffgat brought up jurisdictional issues regarding the permit legislation.

The treaty will place the Riffgat Wind Farm – a joint project between ENOVA and EWE AG – on a “secure base according to international law,” according to the Foreign Office. Thus there is now legal security for both operators and investors.

Federal Network Agency: Riffgat will feed in up to 113.4 MW – decision in the first proceedings for the allocation of offshore connection capacity

The Federal Network Agency has currently selected applications for permission to participate in the capacity allocation process and the respectively made decisions about the connection capacities. ENOVA filed such a request for the Riffgat Offshore Wind Farm.
Of the eleven applications submitted by offshore wind farm operators, eight applications were approved, among others a request filed by EWE AG and ENOVA for a so-called power upgrade for the Riffgat Offshore Wind Farm.

This upgrade enables a performance increase of 5.4 MW for all 30 wind turbines and produces a yield increase of more than 2 percent. The total output increases from the original 108 megawatts (MW) to now 113.4 MW.

The process, established in August, for allocation of the connection capacity has been proven in practice, according to Jochen Homann, President of the Federal Network Agency. Applicants would use the opportunity to orient their requests to the actual connection potential. A cross-cluster auction of connection capacity could thus be avoided, says Homann. This enables a speedy conclusion to the process, and is in the economic interest of the offshore facility operator, Homann adds.
