ESHA celebrates anniversary and achievements

The European Small Hydropower Association (ESHA) is celebrating its 20th anniversary this year.

Looking toward the future, ESHA said a newly adopted renewable energy sources directive paving the way for 20 percent renewable energy by 2020 will bring a new drive for sustainable hydropower development in the European Union (EU).

The organization also said it plans to continue to represent the interest of sustainable hydropower within the renewable energy family, thereby contributing to EU’s security of energy supply, to economic development, and to abatement of climate change.

Representation over 20 years has served to position the small hydro sector and enabled it to effectively promote the beneficial use of hydropower in the EU, ESHA said. It has helped encourage the development of small hydropower — projects with an installed capacity of up to 10 MW — through lobbying and other activities, including conferences, seminars, workshops, and studies.

The non-profit association based in Brussels, Belgium, promotes small hydro plants and emphasizes environmental integration. ESHA was created through an initiative of the European Commission in 1989 and has represented the interests of the small hydropower sector in the EU since that time. ESHA is a founding member of the European Renewable Energy Council. It also is a member of the Alliance for Rural Electrification.

On line reports: Macedonia, Norway, Panama, Peru

New and refurbished small hydropower projects in Macedonia, Norway, Panama, and Peru are now operating.

Utility EVN Macedonia brought on line the refurbished and upgraded 9.6-MW Matka hydroelectric project on Macedonia’s Treska River. The Macedonian Information Agency said Hydropol of the Czech Republic refurbished Matka under a concession to modernize and manage seven small hydro plants. New turbines and other equipment were supplied by GE Norway, while generators were provided by INDAR Spain. Matka, formerly totaling 3.7 MW, was built in 1938.

Norway utility Statkraft began operation of the 2.9-MW Rodberg hydroelectric project in Norway’s Buskerud County. The project uses 60 percent of the water drop between the 206-MW Nore 1 and 63-MW Nore 2 hydro projects by using the minimum flow release from Rodberg Dam. The plant is to have an average annual generation of 15.5 gigawatt-hours. Statkraft said development of Rodberg meets the government’s and Statkraft’s goal of upgrading and extending its existing hydropower projects.

Developer Istmus Hydro Power Corp. has commissioned its 10-MW Concepcion hydropower project on the Piedra River in Panama’s Chiriqui Province.
