Quisqueya I & II, Dominican Republic

"Since we need to match the generation to the mine's load, the advantage of Wärtsilä's power plant is that we can vary the dispatch to match the load without sacrificing efficiency or suffering maintenance impacts."
-Bernerd L. Grill, Commercial Manager, Barrick Gold Mine


In September 2011, Barrick Gold Corporation acquired a majority share in a gold mine located some 100 kilometres from the Dominican capital, Santo Domingo. The mining company quickly placed an order for a state-of-the-art Wärtsilä power plant to satisfy the needs of their new power-hungry mine

The Quisqueya project is a rare combination of two power plants. The largest utility in the country, EGE Haina, jumped on the boat of efficient and  reliable power generation, turning the initial project to a synergetic effort where the total value exceeds the sum of its parts.

Both Quisqueya plants feature Wärtsilä Flexicycle™ combined cycle technology and operate on 12 Wärtsilä 50DF dual-fuel engines each. The power plant will have a net efficiency of 48 %, which is an astonishingly high figure in tropical conditions, with soaring humidity and temperatures above 35°C.
