Paving the way towards sustainable energy
GPSS produces sustainable energy through the development, design and construction as well as via investment.
Supplying sustainable energy to match ever-changing demand requires combining energy sources based on each resource’s distinctive characteristic. For example, wind and solar generation are subject to the vagaries of nature and thus affect the supply of electricity. At GPSS we specialize in developing a broad mix from five technologies to realize the goal of delivering a sustainable lifestyle with safe and reliable energy for all.
Solar power relies on sunshine, and thus is considered a variable power source with a low capacity factor of approximately 13%. GPSS aims to improve generation efficiency and power output by incorporating the best practices of engineering and construction techniques from around the globe, minimizing the cost of electricity produced.
Wind generation in Japan has been perceived as difficult due to the lack of a consistent prevailing wind. The lowering of costs and gaining the trust of local stakeholders remain important issues. We aim to use our experience in running community joint ventures and combine this with the buying power and engineering expertise of the European majors to develop wind farms. This is also complemented by our strengths in financing and developing projects.
Hydroelectric generation has a long history; however, smaller scale reserves have traditionally been difficult to commercialize, and thus many resources have been left untapped. By carrying out EPC internally, GPSS can lower initial capital costs, thereby allowing us to develop previously commercially non-viable projects.
Geothermal energy operates as a base-load power source, running 24/7, maintaining at a very high-capacity factor, similar to nuclear power. It requires the securing of high-temperature geothermal resources. Geoscience and development teams work closely together to improve resource development efficiency. We are developing projects nationwide through forging long-term partnerships with local communities to create such generation businesses.
Methane gas is used to generate electricity from organic materials such as livestock manure and food residues, which can be used as energy resources. The system converts waste that used to be disposed of as rubbish into a form that can be utilized, creating a long-term resource cycle in partnership with the local community.
