Having a power supply serving only the mine, fully independent of the grid, to provide the company with reliable and economic electricity has not always been a viable solution. Remote locations with a minimal on-site infrastructure, or mining operations where the power requirements are likely to vary, are just two examples of sites where normal fixed power plants are not always a feasible investment. The new Wärtsilä Modular Block provides mining sites the opportunity of having their own captive power generating capacity.
The Wärtsilä modular block concept comprises a pre-fabricated, modularly configurated and expandable enclosure. It incorporates medium-speed engine technology with fast-starting and load-taking capabilities, and is able to handle a mine’s large motor starts. Furthermore, it provides a viable opportunity to use power from renewable sources, such as wind and solar, for both environmental and economic gains.
The Modular Block concept includes most of the process equipment needed for converting a simple generating set into a compact power station. Its pre-fabricated, modular design means that it can be quickly and easily installed in just a few weeks. Similarly, it can be disassembled and re-installed at an alternative location should it be necessary or expanded with additional modular blocks to adapt the power supply should the mine capacity increase. Incremental expansion allows the investment costs to be cascaded accordingly. Its rapid deployment from delivery to start-up minimises possible loss of revenues for the mine.
