Steel works - wind
Our client, a major steal fabricator had found that energy had become a major overhead cost and was approached by our consortium about considering siting a wind turbine in return for a power purchase agreement to buy the energy generated by the turbine. A saving of 50% of current energy costs for 20 years indexed linked to RPI and not the energy market led to a decision to install a 500kW EWT wind turbine on the site.
The wind speed on site at 70m high had given a wind speed of 6.6m/s which in turn generated an output of some 1,700,00kWh/year contributing to a sizeable reduction in energy costs.
The machine was connected by HV with an LV connection to the factory to take full advantage of all of the energy produced.
Spectrum provides a full design and installation service for all projects.
Spectrum Energy acted as principle contractor, encompassing the role of CDM co-ordinator and delivering the project from site survey to switch on. The skills of Spectrums engineering team all contributed to the successful design of a complicated metering arrangement and site specific earthing system which coupled with the project management skills of the team delivered a successful installation.
The turbine chosen for the project was a direct drive EWT machine with a 70m tower and 54m diameter blade which is one of the most advanced available today
