Demonstration of Renewable Energy Sources and Demand Side Management Implementation on the Future Smart Island

Water Utilities face numerous challenges in their field of work. Problems of infrastructure aging and high replacement costs lead to lack of finance for operation and maintenance. Energy is required in all stages of water production and distribution, from pumping and treatment to transportation. Hence, the energy costs are of great concern for the water utility companies. In a last decade there has been an increase in research on demand side management, which was followed by development of numerous educational programmes to encourage producers and users to conserve water reserves and to efficiently use available water. Usage of ICT and IoT technologies will also play an important role in future water systems, and it will allow for easier implementation of efficiency measures. Therefore, the overall objective for the water utilities is to be able to holistically manage their operation in a flexible way and be focused on decreasing the water losses, save energy and water, and at the same time promote social and environmental sustainability, while having high quality of service. This paper studies the implementation of renewable energy sources on the island basis. Moreover, the possibility of demand side management is investigated which gives the opportunity for the water companies to operate more efficiently and receive additional remuneration and/or increase savings regarding the energy consumption. Case study for the implementation of the developed model shows demand response capabilities in the water network on the islands of Cres – Lošinj archipelago and possibility to integrate solar PV plants for electricity self-consumption of water and wastewater treatment company
