The Municipality of Zaanstad has negotiated a new energy contract, that saves energy, stimulates the local production of renewables and reduces energy costs substantially. The young energy company Green Choice was selected as a contract partner for the coming years. The contract stipulates that the energy consumption of the Municipality will be reduced a full 15 % in the first two years. Green choice profits when a further reduction is realized, an innovative element in the contract that gives the energy company a clear interest in energy savings. The company will also assist Zaanstad in the smart management of energy production and consumption.
