Green Island Group offers one-stop turnkey solutions, providing communities with green prosumer-owned utilities. We manage, finance, design, install, and operate utilities supplying power, water, climate, and waste-to-value systems - with no use of fossil fuels. We employ a synergetic approach to designing DER utilities, combining many tried and tested green technologies to work in concert. And we create shared value by aligning interests between stakeholders and placing ownership of utilities in the hands of prosumers.
