An group of international scientists has developed a mathematical model to design hybrid renewable energy systems relying on pumped hydro storage for islands. According to their analysis, which was applied to the Ometepe island in Nicaragua, a similar system could provide a cost of energy ranging from €0.047/kWh to €0.095/kWh.
Canadian behemoth Atco has purchased the rights to develop the 325 MW Central West Pumped Storage Hydro Project in Central West New South Wales and credits the investment to policy certainty from the NSW Government. As a significant firming agent the project is ideally placed in the state’s proposed Central West-Orana Renewable Energy Zone.
A study has analyzed the technical and financial feasibility of floating solar at hydro power plants. The report concludes floating PV reduces evaporation from hydropower reservoirs and the water saved can be used to generate more electricity.
Gambia’s national utility is seeking proposals for an energy and water audit of its water operations. Selected consultants will assess the possibility of using solar to improve energy efficiency. The utility will consider floating PV, rooftop arrays, and solar pumps.
Australian researchers have identified more than 600,000 sites suitable for closed-loop pumped-hydro energy storage projects across the globe. “Off-river” pumped-hydro is not only able to overcome the typical topographical issues of conventional pumped-hydro but is also cheaper.
Centennial Coal has secured more than US$3.8 million in government funding to assess the feasibility of turning a coal mine near Newcastle, New South Wales, into a pumped hydro storage site that could supply 600 MW of renewables to the grid.
The first 5 MW portion of the large floating power plant was connected to the transmission system of a 404 MW hydropower dam on the Black Volta River.
The renewables business is set to acquire the SN Power hydropower operator belonging to Norwegian state-owned private equity business Norfund, with the $1.17 billion deal expected to go through in the first half of the new year. Scatec said the transaction could offer floating solar opportunities.
The U.S. based researchers said linking solar with hydro in a full hybrid system configuration may result – at best – in the deployment of 7,593 GW for an estimated annual power generation of 10,616 TWh and a 20% reservoir coverage. And combining solar with hydro in this way brings further benefits, including improved system operation at different time scales, more opportunities for storage thanks to pumped hydro, increased utilization rates of transmission lines, reduced PV curtailment, and lower interconnection costs and water evaporation.
