Commissioning of Hillekopf Wind Farm

Bunderhee/Medebach: The development contract for a wind farm project at Hillekopf (Sauerland) was awarded by the State Foresty Association of North Rhine-Westphalia, Forest and Wood NRW, in the context of a bidding procedure. Around 20 developers nationwide took place in the bidding. The bidding process was won by the East Frisian project developer ENOVA.

The ENOVA Group has many years of experience in the design and implementation of onshore and offshore wind farms. In recent years, they have gained expertise in the development of wind plants in forest areas. The areas for the Hillekopf Wind Farm are located mainly in the national forest of Wald und Holz NRW. Projections indicate that the area around the 805 meter high Hillekopf mountain, in the northern part of the Rothaargebirge, is a very good wind site.

Wald und Holz NRW has for the first time leased a forest area for use as a wind energy site. ENOVA looks forward to working with the forestry office, the municipality, the municipal utilities, as well as the people in the region, says the managing director of the group, Helmuth A. Brümmer.

On the wind farm area of Medebach, north of the village of Kuestelberg, up to six wind turbines can be built according to current plans. Recently, avifaunistic observations (ornithology) have been initiated for species conservation reports, which are required as part of the approval process.

Repowering Memgaste

This year in the municipality of Moormerland, a wind turbine built in 1992 by ENOVA was repowered. The site is located in the northern district of Leer and is one of the oldest wind energy projects in ENOVA’s portfolio.

Repowering replaces the existing wind turbine with a newer and more powerful one. The site’s yield can thus be optimized and the Memgaste wind turbine’s energy output is tripled. The old system, Type Icon M 530 had a rated output of 250 KW and a hub height of 30 meters. Its rotor diameter was 26 meters. In its place is now an Enercon E-53 with a rated output of 800 KW, a hub height of about 73 meters, and a rotor diameter of 52.9 meters.
In October, the tower parts for the wind turbine were delivered and quickly installed. The final assembly of the enclosure, hub, and rotor blades was completed in November of this year. In December, the wind power plant was put into operation.

For ENOVA, Memgaste is the third successful repowering project, in addition to a single system in Neermoor and the Holgaste Wind Farm.

Offshore wind farms promote biodiversity

The Federal Maritime and Hydrographic Agency (BSH) presented a study at the end of October this year on how offshore wind energy parks affect biodiversity in the North and Baltic Sea.

In the investigation, the authority concluded that the foundations of the wind turbines form artificial reefs, around which seashells, starfish, sea anemones, sea lilies, and fish such as mackerel and long-spined bullheads settle.
The danger to seabirds was also lower than expected. The movements and lighting of wind turbines seem to scare birds and therefore reduce the risk of collision.

The test site “Alpha Ventus,” 45 kilometers off the island of Borkum, was used for the study. At the wind farm, which was commissioned in 2010, novel methods such as fish sounders and digital imaging systems were used, in which software analyzed bird movements.
Follow-up data showed no effect on strictly protected marine mammals such as porpoises. The animals avoided the wind farm field during pile driving, but returned after completion of construction.

According to federal government plans, wind farms with a total of 25 gigawatts (GW) of power should be installed by 2030. The BSH is responsible for authorization and environmental concerns. Based on current study results, the authority shall set a standard (“StUK4”), which will be binding in future for the builders of offshore wind turbines.

In the 12-mile zone of the offshore wind farm RIFFGAT (ENOVA & EWE AG), a settlement of European lobsters is to be explored as part of a pilot project. Researchers from the Alfred Wegener Institute in Bremerhaven already began raising about 3000 lobsters at the beginning of this year. They are to be reintroduced into the wild in the foreseeable future. The project will provide information on whether lobsters can successfully settle between wind turbines.

Wind energy in focus: The 3rd Emder Offshore Days

On September 5, the third Emder Offshore Days came to an end at the University of Emden/Leer.
ENOVA was represented at the two-day offshore industry networking meeting, both as a major sponsor and as part of the lecture program. The event was focused on the mutual exchange of ideas in various panel discussions, as well as the accompanying exhibition. Parallel practical and scientific lectures were available to interested attendees.

In addition to the exhibition attendees, regional economic and political representatives came together to encourage offshore wind energy in and for the region. One focal point of the meetings was an event on the evening of September 4 in the Johannes a Lasco Library in Emden. Helmuth A. Brümmer, Managing Director of the ENOVA Group and Dr. Torsten Köhne, CEO of EWE AG, presented to 300 guests the need for reliable conditions in the offshore industry, in relation to the realization of RIFFGAT, Germany’s first commercial offshore wind farms in the North Sea.

In his presentation, Helmuth A. Brümmer covered the challenges of the offshore wind farm RIFFGAT’s approval process and illustrated the main obstacles in the 12-year planning phase. ENOVA initiated the project in the mid-90s as project developer and obtained approval. Brümmer also highlighted the rapid implementation of offshore wind farms, pointing out the remarkable achievement it was for all parties to build thirty wind turbines in just fourteen months. Following the presentation, there was an opportunity for mutual exchange and further discussions. Brümmer appeared satisfied with the outcome of Emder Offshore Days for ENOVA. The goal, to make themselves strong in the region and for the region, had been met. The great echo of Offshore Days in the industry was also enjoyable, according to Brümmer. Offshore wind energy has found another high-profile platform.

INNOGY Nordsee 2 and 3 obtain approval

On August 27, 2013 the Federal Maritime and Hydrographic Agency (BSH) granted approval for the offshore wind farms Innogy Nordsee 2 and 3, initiated by the East Frisian ENOVA Group. The BSH therewith approved another 108 wind turbines. Fourty-eight wind turbines account for Innogy Nordsee 2, sixty on Innogy Nordsee 3. The project areas are part of the wind farm cluster Innogy Nordsee 1, 2, and 3, located about 40 kilometers off the island of Juist. Up to 162 wind turbines can be installed with a capacity of approximately 1,000 megawatts (MW). Innogy Nordsee 1 already received approval from the BSH in April 2012.

With this approval, Germany’s largest offshore wind farm complex is now fully developed. ENOVA initiated the project as a project developer. At the end of 2008, RWE Innogy GmbH acquired the project rights and divided the territory into three subareas. ENOVA led the development of the projects through to granting of approval. For ENOVA, this is already the sixth approval for an offshore wind farm. ENOVA here again demonstrates its position as one of the largest offshore project developers in Germany. Further projects for which ENOVA obtained approval include the offshore wind farms Delta Nordsee 1 and 2, and the recently completed wind farm RIFFGAT in the 12-mile zone.

Offshore wind farm RIFFGAT inaugurated

This past weekend, Germany’s first commercial offshore wind farm Riffgat was inaugurated. Present at the ceremony was Lower Saxony Prime Minister Stephan Weil (SPD). During a sightseeing flight, Weil was shown the systems by EWE CEO Werner Brinker. Weil spoke of a pioneering project for future technologies.

The reason for opening the wind farm without electricity production is the very lengthy recovery of the polluted munitions areas, which delayed connection to the power grid.

Prime Minister Stephen Weil (SPD) congratulated those responsible for the completion of construction and called for an expansion of offshore wind farms. Offshore wind energy is able to provide baseload and is therefore the technology Germany needs to compensate for nuclear power.

IHK Offshore Stammtisch at ENOVA

This year, the sixth IHK Offshore Stammtisch took place in Bunderhee at ENOVA headquarters. The networking meeting of the offshore wind industry, which is organized by the University of Emden/Leer and the chamber of commerce twice a year, has become an integral part of the industry and serves as a bridge between the annual “Emden Offshore Days.”

After a brief welcome by Prof. Gerhard Kreutz of the University of Emden/Leer, the meeting dealt with the positive development of offshore wind energy and the six projects that are currently under construction in the North Sea. Over the course of the event, owner and managing director of the ENOVA Group, Dipl.-Phys. Helmuth A. Brümmer, held a lecture on the offshore activities of ENOVA, which was also the thematic focus of the evening. Afterward, Dipl.-Ing. Dirk Warnecke introduced project development and construction on the high seas, using the offshore wind farm Riffgat as an example. After completion of the lecture program, a mutual exchange of information took place.

Offshore wind farm RIFFGAT is completed

Construction of the last wind turbine in the offshore wind farm RIFFGAT was completed over the last few weeks. With its thirty SWT 3.6-120 wind turbines, RIFFGAT is the first ready-built commercial offshore wind farm in the German North Sea.

The installed wind turbines have a single output of 3.6 megawatts (MW) and a rotor diameter of 120 meters. The hub height is 90 meters, and the total height from water surface to the upper rotor blade tip is 150 meters. With a total output of 108 MW, the offshore wind farm will produce enough electricity for 120,000 homes. On August 10, the wind farm will be inaugurated. Current is not yet flowing. The network operator Tennet is still working on completing the last section of the 50 kilometer submarine cable for network connection.
