Onshore, Offshore Wind Power Generation

Wind from land, ocean and mountains,
all wind resources are
converted to energy.

We promote the construction and management of on-shore and off-shore wind power plants
with an aim to spread and increase wind power generation that utilizes nature's unlimited wind resource.

Overview of Onshore Wind Power Generation

Wind power generation is spread across the globe
as a clean source of energy that does not emit carbon dioxide.
SB Energy has initiated the construction and management of wind farms.

Wind Farm HamadaWind Farm Hamada

Wind Farm Hamada

“Wind farm Hamada” is constructed in Kanagi Town, Hamada City, Shimane Prefecture. The generation capacity of the total 29 wind towers is approximately 48,430kW (48.4MW) with an estimated annual output of 85,000,000kWh. SB Energy has invested in this joint project with two other corporations.

Business Plan

Suitable sites for wind farms are decided based on existing materials and observation data from the Japan Meteorological Agency. Once a suitable location is found, wind strength and occurrence of turbulence are studied using NEDO's local wind map and wind simulator.

Wind Pattern Investigation

A wind observation point is selected by taking into consideration the theoretical study results and surrounding topography of the proposed location of the wind farm.
At the wind observation point a truss or monopole style wind observation tower, 50-60m tall, is built and data such as wind direction, wind speed and air temperature etc. is recorded every 10 minutes. The proposed site for the wind farm is observed for 1~3 years to see if wind is suitable for electricity generation all year round. This data is used to estimate the annual wind power generation of the farm.

Environmental Impact Assessment

At the time of power plant construction, we forecast and evaluate the potential impact on the natural environment and the living conditions of the local residents. Not only for the wind power plant with total capacity of more than 10,000kW (more than 75,000kW for Type II business), with which the environmental impact assessment law is imposed, SB Energy implements voluntary environmental impact assessment. We plan a project in a careful manner by reflecting ideas and opinions collected from local residents through briefing sessions.

Consideration for environment and safety during the development phase

The wind farm development is a long process from planning, construction and until commercial operation.SB Energy places importance on the environment and strives to be accepted by the local communities.

Material delivery at night time

We are making our best effort to avoid disturbance to the local community by delivering construction materials during the night time, low traffic hours with cooperation of the local community and the police officers.

Overview of Offshore Wind Power Generation

Stable and sustainable offshore wind is converted to large capacity of renewable energy

Offshore wind farms, compared to onshore wind farms in mountains and plains, can continuously obtain a large wind power and stably generate a large amount of electricity as the wind flow is not affected by the surrounding terrain. Being a maritime nation, Japan is blessed with wind conditions in the surrounding waters. Expectations for the potential of offshore wind power generation is great and technological development is progressing rapidly. SB Energy will focus its efforts on offshore wind power generation.

Wind power generator, inverter and grid connection substation comprise a wind power plant. A large wind power generator could be taller than 100 meters in height, requiring a wide space for construction, which makes it essential to have adequate environmental impact assessment, satisfying ground survey, a sufficient design and a good maintenance plan. SB Energy spends a few years to execute surveys on the project site and communicate closely with the local residents before operationalizing a project.
