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.

New appearance for the anniversary

ENOVA turns 25 – and will celebrate this birthday with a new corporate design.

The key date was September 23: The new corporate design was to be ready just in time for the start of the “Wind Energy 2014”. It worked! Visitors to the exhibition won’t miss the new, bright red booth. The new corporate image will be presented during the anniversary celebration on September 26 to business partners, companions, and friends of the company, at the Friesian horse breeding farm Brümmer “The Polderhof”, next to ENOVA headquarters.

Rotor as a key theme

For the relaunch of the corporate design, a typical ENOVA motif was consistantly used: the rotor of a wind turbine, set free and standing alone, is found both in the new company logo and on a red background on all of the East Frisian wind farm developer’s printed materials. “The wind is our most important employee,” says physicist and Managing Director Helmuth A. Brümmer, who founded ENOVA in 1989. It’s only natural therefore, that the “windmill” was placed at the center of the new image.

ENOVA Corporate Design

From pioneer to industry leader: ENOVA in 25 years

“Wind is what drives us.” – This phrase describes ENOVA, the East Frisian company based in Bunderhee, like no other. Founded in 1989 by Helmuth A. Brümmer, the wind energy project developers and service providers look back on 25 years of history today. The anniversary is celebrated not only with an event on September 26, but with a completely new corporate design.

Vision from the beginning

When physicist Helmuth A.Brümmer founded ENOVA in 1989, he demonstrated one thing in particular: vision. Even then he was consistently set on the development of sustainable solutions and the protection of the environment, and placed these maxims at the core of his actions. Success proved him right: Today, ENOVA is one of the oldest and most experienced German project development firms in the field of renewable energy. A pioneer of wind energy.

ENOVA plans, implements, and manages renewable wind energy projects, whether on land or on the water. From the first draft during approval stage, to handover and commissioning. Around 200 megawatts have already been installed in the Federal Republic of Germany, and many more are planned. Out of a two-man operation, a corporate group with 40 employees and counting has developed over 25 years. The East Frisian company will celebrate this positive development on September 26, with an anniversary event in the riding hall of the Friesian horse breeding farm Brümmer “Der Polderhof” located next to the old manor that houses ENOVA’s headquarters.

Anniversary celebration and new public image

The new corporate design focuses on milestones in the company’s history. On the new website and in the new brochure, the Holtgaste Wind Farm can be found again, which was not only one of the first in its time in Ostfriesland, but also created attention with its extensive repowering in 2012. And of course RIFFGAT – the first commercial offshore wind farm in the German North Sea, implemented by ENOVA together with EWE AG.
Milestones in the company’s history
As a project developer, general contractor, and service provider, ENOVA has planned over the last 25 years numerous onshore projects throughout Germany.
Since 1998, ENOVA has been planning offshore wind farms, and is among the largest offshore project developers in Germany. To date, approval for approximately 1,500 megawatts were obtained and development rights were sold to utilities like EWE, RWE, and E.ON. Further projects are currently in the approval process.
The RIFFGAT Wind Farm, a joint project between EWE AG and ENOVA, has become a milestone in the company’s history. The project was honored this week by the Renewable Energy Cluster Hamburg at the Hamburg Wind Energy Fair with the “German Renewable Award” as “Project of the Year.”
In addition to its own projects, ENOVA is working in partnerships on current and future plans on land. These partnerships for new projects are with public utility and energy companies, mainly in Lower Saxony, Rhineland Palatinate, Hesse, and North Rhine-Westphalia. ENOVA utilizes its offshore experience collected from numerous own projects, as well as the construction of the offshore Riffgat Wind Farm, in its role as a service provider for other projects.

Important targets for the future

Currently, the share of renewable energy in electricity consumption is approximately 30 percent, about a third of which comes from wind power. According to industry projections, renewable energy will cover almost half of Germany’s total electricity needs by the year 2020. The integration of wind energy into the heating market is meaningful, because the potential is twice as large as that of the electricity market. “We are facing the challenges,” said ENOVA’s Managing Director Helmuth A. Brümmer. In photovoltaics as well as for wind power grid integration, the storage of energy as well as the adjustment of energy production and consumption are becoming increasingly important.

Riffgat: Award for the best project in the field of renewable energies

Innovative renewable energy project recognized

The Renewable Energy Cluster Hamburg (EEHH) honors personal commitment to renewable energy with the German Renewable Award, the first German prize in the industry. The award ceremony will take place for the first time this year at the 2014 Wind Energy Fair in Hamburg, and not only be distributing awards in the categories “Product innovation of the year” and “Project of the year,” but also “Student work in wind” and the “Lifetime achievement in wind.”

This year, Riffgat was selected by an independent jury for best project. The offshore wind farm was developed by ENOVA and implemented in cooperation with the Oldenburg-based utility provider.

The offshore wind farm has been feeding electricity into the German grid since the start of the year. The award ceremony was held in Hamburg’s Fish Auction Hall on September 23, 2014

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.
