Romanian companies advance small hydro projects
Hydro developer SC Hidro Este SRL is working to construct four small projects in Romania.
As an EU member, Romania is obligated to attempt to supply a minimum of 35% of its electricity from renewable energy sources, including hydropower, by 2015 and 38% by 2020.
SC Hidro Este plans to build the Pascoaia 1, 2, and 3 projects on the Pascoaia River and Priboiasa 1 on the Priboiasa River. The projects are anticipated to cost RON38.2 million (US$13.2 million) to build and RON27.6 million ($9.6 million) to equip. This includes turbines, generators, transformers, and a supervisory control and data acquisition (SCADA) system.
In other news, Romania hydro development company Rott Energy s.r.l. plans to develop a portfolio of 25 small projects totaling 40 MW.
Rott Energy said it is working with consultant Price Waterhouse Coopers to obtain EU funding for two of the projects, of 1.7 MW and 2 MW, for which it already holds permits. The 1.7 MW plant is to be built at Alba and would feature two powerhouses, each containing a Pelton turbine. The plant would have annual generation of 8,035 MWh and an estimated investment of €3.2 million ($4.6 million).
The company said its shareholders have wide experience in the Romania business environment but little experience in hydropower. Construction is due to begin soon on its first two plants, and General Manager Octavian Manastireanu said Rott seeks an investment partner with experience in hydropower and development funding. Rott proposes to assign 50% to 100% of each project to this partner.
Work under way at two Swiss hydro projects
Swiss utility Gruyere Energie SA is working to refurbish generating units at the 4.5 MW Charmey hydro project on the Jogne River.
Gruyere Energie produces nearly 12% of its electricity from Charmey, which was built in 1893 and relocated in 1957.
The utility will renovate and automate three generating units in three lots: Lot 1 turbines; Lot 2 generators; Lot 3 control group, automation and pipe work.
In addition, Swiss utility Romande Energie plans to redevelop the 725 kW Rivaz 2 project on Forestay Creek at Forestay Falls in the Lavaux District.

Romande plans a CHF5 million (US$5.6 million) redevelopment of Rivaz, the site of a historic mill above Lake Geneva, to utilize the full 183 meters of Forestay Falls, compared to 63 meters previously. The new project would increase generation capacity seven times to 2,500 MWh per year.
Pumped-storage scheme planned for island of Alderney
Tidal energy developer Alderney Renewable Energy is planning a small pumped-storage project on the island of Alderney in the Channel Islands, media reports indicate.
The 3 MW scheme would use tidal devices to power a system that would pump sea water into a land-based reservoir before releasing the water through at least one hydro turbine, reports indicate. The pumped-storage scheme would supply an estimated 90% of the island's power demands.
The Channel Islands are an archipelago of British Crown Dependencies in the English Channel, off the French coast of Normandy.
Recently, ARE signed an agreement to lease a site near Braye Harbour, Alderney, as the site of the turbine pump house and reservoir. ARE has begun an environmental impact assessment to obtain marine consent from the Alderney Commission for Renewable Energy. The project could be completed by 2012.
