Green Energy Group (GEG) has today announced the launch of its new C64 well-head condensing power plant. The C64 performs 6.4 MW and has a modular design based on standard manufactured components. Being flash based, the C64 is suitable for temperatures above 190 degrees Celsius. The plant can operate independently for each well or be organized in power farms to provide a similar power output to large traditional geothermal power plants.
The C64 plant is delivered in 40-foot ISO containers on-site, and the standardization of key components allows for quick installation. The first power online can be expected within 12 months after ordering.
“Our solution has been developed to counter both the long term delays in supply of power online and prohibitive investments costs associated with the deployment of traditional geothermal power plants. The C64 deliver power online from the completion of the first well, providing for step-by-step utilization of the geothermal field, without waiting until a critical mass of productive steam wells are drilled. For our customers this represents a significant advantage over the deployment of traditional power plants enabling the early supply of electricity and importantly access to revenues earlier in the investment cycle” said Stig Torvund, GEG’s Sales and Marketing Director.
Optimal energy utilization The independent well-head power plant C64 enables optimum power to be produced from each individual well regardless of their differing outputs and characteristics. The concept negates the needs of traditional power plants for well redundancy, or an excess steam buffer to cater for well failures and allows all wells to be utilized. The C64’s modular design also makes it possible to generate electricity from remote wells that are outside the topographical reach of large traditional plants.
Rapid deployment The C64’s modular design, based on standard manufactured components, allows for significantly reduced lead times and early power online. Today, GEG can deliver power online within 12 months of ordering the first C64 power plant and thereafter rapid deployment, at a rate of one C64 plant per month, can be achieved.
Lower risk with modular flexibility The C64 modular power plant is delivered in 40-foot ISO containers and each module is ready made at the factory allowing for quick installation. It is designed to operate independently for each well, but can be organized in power farms to provide a similar power output to large traditional geothermal power plants.
In the event of a well failure, the C64 is designed to be decommissioned, transported and redeployed on a second well, maximizing the return on investment. Equally importantly, the failed well can be returned to its original state thus preserving the environment.
Reduced cost per megawatt The C64’s modular design based on standard manufactured components enables a highly competitive capital price and allows for easy maintenance and access to spare parts.
Focusing on the characteristics of each well independently, the C64 is able to adjust turbines to achieve a high level of power output efficiency, driving down electricity production costs.
The C64 also deploys an advanced control system providing real-time operational data, allowing for early remediation action and preventative maintenance thus avoiding unnecessary downtime and associated costs.
