Whether your are a mining operator or a remote community, integrating wind or solar energy with your diesel micro-grid will dramatically improve the way you feel about energy. A renewable micro-grid allows you to cut operational expenses, increase fuel security and build social capital.

What is the opportunity?

Maximum savings are realized at the largest system size which maintains grid stability without battery storage.

 

Advancements in system controls, solar inverters, diesel controllers and auxiliary components have made hybrid diesel generation economically attractive and operationally robust. These advancements have brought new opportunities to lower operating costs, diversify fuel sources, and simultaneously build social capital. By transforming mature military technology that is used to power some of the most remote bases on the planet, Bella Energy has developed a reliable method to support remote diesel micro-grids with renewable energy.

The integration of renewables into a micro-grid does not replace existing generation. Nor, should one expect renewables to power the micro-grid full time. Renewables are currently adept at providing a supplemental, low cost fuel source by producing a substantial part of the facility’s daytime load, while the diesel maintains grid stability and satisfies the balance of the daily power needs. Despite the limited capacity factor and intermittent nature of renewables, there is a financially compelling case for micro-grid integration.

 

The renewable advantage

Cleaner.

Renewable energy reduces your micro-grid's environmental impact. In regions where carbon emissions are priced this can generate additional savings and new revenue streams.

Less Expensive.

Diesel generated electricity is some of the most expensive electricity on the planet. Properly sourced renewable generation can provide substantial savings and a more predictable energy budget.

Social Capital.

For mine operators maintaining community support can be a real challenge. A renewable micro-grid is visible evidence of your sustainability efforts and can be a valuable asset to the community after operational shutdown.

More Secure.

Transportation of diesel fuel across rough and remote terrain is expensive and full of risk. Environmental damage from spills, or loss of production from missed shipments are just some of the many reasons to invest in a renewable micro-grid.

Sample system diagram

Hybrid generation controllers allow Bella Energy to integrate renewables into diesel micro-grids. Proper controls are essential for reliable and stable grid dynamics. Renewable generation supplements production from the diesel generators. The interplay between each production asset is monitored by the control unit, which ramps the diesel engines depending on renewable asset generation.
