Should run-of-river plants be integrated with energy storage?
Integrating run-of-river hydropower plants with energy storage is being demonstrated for its technical and economic benefits by three national laboratories.
What are off-River pumped hydro storage sites?
Prospective off-river pumped hydro storage sites vary from tens to hundreds of hectares, much smaller than typical on-river hydro energy reservoirs. Tunnels and underground power stations, as assumed in the costing methodology, can be used in preference to penstocks to minimize other surface impacts.
Which energy storage size is considered a potential lower reservoir?
We explored a range of energy storage sizes of 2, 5, 15, 50, and 150 GWh. Every potential reservoir with a height difference (head) of 100 to 800 m below the target reservoir and with a height difference to separation ratio more than 0.03 (3% slope) were considered as a potential lower reservoir.
What are the benefits of locating reservoirs near rivers?
The reservoirs are also typically small, of the order of tens to hundreds of hectares. Locating upper reservoirs away from rivers and the small area of the reservoirs greatly reduces the environmental impact. It also minimizes the need to manage large flood events, which substantially reduces construction cost.
What types of energy storage technologies are available?
Wind turbines and solar photovoltaic (PV) collectors dominate new electricity capacity additions. Wind and solar PV are variable generators requiring storage to support large fractions of total generation. Pumped hydro energy storage is the largest, lowest cost, and most technically mature electrical storage technology.
