Sometimes, one plus one does not equal two. The 25,000 inhabitants of Quisqueya, a small town close to San Pedro de Macorís, in the Dominican Republic, know so. In September 2011, Barrick Gold Corporation acquired a majority share in a soon-to-be-opened gold mine, some 100 kilometres away from the Dominican capital, Santo Domingo. As soon as the mining company understood the needs of their new power-hungry mine, they decided to place an order for a state-of-the-art Wärtsilä power plant. The way in which Barrick, its host country and Wärtsilä would cooperate for the greater good came to exceed the initial expectations of any of the three involved parties and strike gold in an unforeseen way.
