Economics of Behind-the-Meter Power Generation at Ontario Mines


Mr ILYA KOGAN (Application Engineer - GE Mining)

Growing energy prices and stressed power grids dictate rapid expansion of distributed power generation serving industrial facilities. Gas-fueled generators installed at mine site can operate in parallel with the grid and offset mine net consumption in the hours determining IESO Global Adjustment fee critical for the electricity bill. Same generators can serve for the emergency backup power supply. In the current Ontario market, such projects are highly economical and can save over $0.5M annually per 1 MW of installed capacity. A number of them are currently underway, including some in the mining sector. A case study will be reviewed.
