Sumitomo and J-Power Systems to Install Submarine Power Cables Between Taiwan and Penghu Islands

Sumitomo Corporation and J-Power Systems Corporation have won a joint contract to install submarine power cables between the main island of Taiwan and the Penghu Islands, located about 60 km west off the southwestern coast of the main island.

This is a full turnkey project worth about 32 billion yen and involves the installation of six single-core 161kV XLPE power cables with optic fiber. While JPS will manufacture the submarine power cables and auxiliary equipments, Sumitomo Corporation will install the cables and conduct other related civil and engineering work. With a total installation distance of 350 km or longer and an installation depth of up to approximately 150 m, the project will be one of the world’s largest installations of high voltage XLPE submarine cables of this kind.

The Penghu Islands depend primarily on fishing and tourism as their local industries and are blessed with beautiful natural areas. Taiwan is fostering the redevelopment of these islands in order to transform them into “low-carbon islands” to be a model of a future low-carbon society achieved through protection of the island’s nature reserves. As part of these efforts, Taiwan is promoting a shift toward the use of renewable energy by discontinuing the operation of the local diesel power plant and has already constructed a new wind farm. The project to be implemented by Sumitomo Corporation and JPS will play an important role in helping stabilize power supply to the islands during the transition period and is regarded as an essential project for their transformation into these “low-carbon islands.”

In Taiwan, demand for electricity will increase in step with high economic growth, so the Taiwan is also placing importance on energy conservation and on the reduction of environmental impact. Accordingly, multiple projects are being planned in the region to replace aged power plants with more energy-efficient supercritical coal-fired power plants and with natural gas-fired combined cycle power plants. Sumitomo Corporation will proactively implement the project with JPS to contribute to Taiwan’s economic growth and a reduction in environmental impact by capitalizing on its wealth of expertise in the global power business.

2nd Annual Offshore Power Cable Engineering and Reliability Forum

This exclusive BIS forum will showcase an analytical insights into how industry leaders are reducing risk and improving efficiency during offshore power cable installation. Participants will learn how to increase cable integrity and manage cost during offshore projects. This interactive forum will explore effective and safe maintenance of offshore cables in deeper, harsher environments. With a two day intimate forum followed by half a day workshop, joining together key industry professionals to discuss, brainstorm, share experience and partake in exclusive networking sessions in a flexible and dynamic platform – together shaping the future of the market.

As Europe strives to meet its 2020 renewable targets the need for infrastructure increases and the integration of renewable energy into the European grid along with the necessity for trade is of huge importance. HVDC offshore cables are a vital investment; both of time and money, and any challenges arising could result in operational and financial losses. An insight on how to efficiently cope with the changes and keeping up with market trends is needed.

This BIS GROUP Forum will allow leading electricity cable and interconnection players to exchange and discuss experience on reliable offshore power cable monitoring, protection strategies, repair and installation technologies that are vital for operating in cost-efficient manner. The forum will also provide solutions and strategies on how to overcome the challenges of laying and installing of offshore power cables in deep water / far offshore.

66kV Offshore Wind 2015

The only networking event on 66kV array grids.

66kV Offshore Wind is a technical event for experts in the wind industry. The goal is to provide a clear path to commercial implementation of 66kV array grids. By exploring developer requirements, WTG capabilities and equipment certification, we hope to reduce both uncertainty and time to implementation for 66kV offshore wind.

The conference aims to:

  • Evaluate project requirements to select 66kV inter-arrays
  • Explore turbine requirements for use in 66kV systems
  • Review certification procedures for higher voltage equipment
  • Evaluate the technology and cost impacts on transformers, cables and switchgears
  • Understand the need for reactive power compensation in offshore substations
