Utilize your unused land spaces

Your land could turn itself into a source of renewable energy.We want to work with you to realize your land's potential.

Shizen Energy Group Characteristics

Our aim is to construct power plants together with people from the local community.
In each region of Japan, we will plan power plant designs suited to the land based on its characteristics while asking land owners their thoughts on its utilization and consulting with them.
We offer consulting not only on photovoltaic power plants but also on wind power plants.
We will also coordinate with power companies and obtain the necessary permits from authorities.

Shizen Energy Group Achievements

To date, we have carried out power plant construction projects on land owned by municipalities, private organizations and individuals.
The know-how we have cultivated all over Japan and throughout the world regarding everything from business development (negotiations with power companies, permit applications, etc.) on the land to EPC (Engineering, Procurement and Construction) makes it possible for us to successfully build your power plant under various conditions.
Ask us not only about photovoltaic power plans but also about wind and small hydroelectric power plants.

Is your land suitable for a photovoltaic power plant?

Following is a brief list of check items. Contact us to find out your land's fit more thoroughly.


Size of your land

Currently, we are assisting with considerations for installation on land that is 0.3 hectares (3,000 m2) and over.

  • A photovoltaic plant on a land with area of 1.0 ha (about 5,000 tsubo) generates approximately 1MW (1,000 kW) of electricity.

  • We currently work with owners of lands greater than 0.3 ha (about 1,000 tsubo).

  • Each land space is different. Feel free to talk to us about your land.

  • Ideal lands include former manufacturing facility spaces and golf courses.

Amount of sunlight
  • The more sunlight your land gets, the more electricity your land (or the plant) will be able to generate.
  • Our database will assist you to simulate how much sunlight your land space actually receives throughout a year ("irradiance")

Simulate irradiance.


Structures on adjacent land spaces

Ideally, there's no natural or artificial structure that blocks sunlight in east, west and south of your land, like a mountain, trees and buildings.

  • (Example) solar power plant installed to fit
    A land fit for installing a photovoltaic plant
  • (Example) solar power plant installed at non-conforming
    A land NOT fit for photovoltaic plant

Nearby transmission lines

There needs to be transmission lines nearby your land so that generated electricity can be sent to the grid.

 

The presence of lines for the distribution/supply of power

 


Land condition and registration ("chimoku")

Time needed for obtaining permits, designing and constructing may vary depending on land conditions and registered use of your land.

Is your land suitable for a wind power plant?

wind power

Wind conditions

Average annual wind speed must be at least 6 m/s (at 50 m).

Restrictions

It must not be restricted land, such as national/quasi-national parks, protected forests, etc.

 

Installation environment

The windmill(s) must be outside a radius of at least 500 m from private houses.

 

Nearby power lines

There must be power lines nearby to transfer the electricity generated by the power plant.

 

Transportation route

Windmills are large structures.
The blades can be 50 m or longer, so there must be a road suited to transportation of such large structures.

Is your land suitable for a small hydroelectric power plant?

小水力発電所イメージ

Types of locations

General rivers, agricultural water channels, erosion control/afforestation dams, water supply facilities, etc.
In addition to the above, maintenance discharges from dams, discharged water from existing power plants, sewage treatment facilities, circulated water from buildings, etc. can be used.

 

Natural conditions

  • Well-kept mountains and forests
  • Easy to obtain effective head
  • Flow is stable year-round
  • Quality of water to be used is favorable (low influx of debris, leaves, driftwood and dirt) etc., etc.

Water rights

Falls into category of customary water rights/licensed water rights
Does not require application for water rights (point where water from agricultural water channels becomes wastewater, point where river water flows into purification facility, etc.)
