Norwegian Water Resources and Energy Directorate Micro- and mini hydropower
NVE’s main responsibility The Norwegian Water Resources and Energy Directorate is a directorate under the Ministry of Petroleum end Energy and is responsible for the management of Norway’s water and energy resources. NVEs function is to ensure an integrated and environmentally sound management of Norway’s water resources, promote an efficient energy market and cost-effective energy system and take initiative to promote efficient energy use. The Directorate has a central role in national flood contingency planning and has the overall responsibility for maintaining national power supplies.
Micro- and mini hydropower Micro- and Mini Hydropower in Norway focus on rural electrification and/or extra income/ reduced expenses for the farmer
Micro- and mini hydropower Micro hydro is power stations less than 100 kW Mini hydro is power stations between 100 and 1000 kW Small hydro is power stations between 1000 kW and kW. The phrase “small hydro” is also often used for all power stations less the kW.
Micro- and mini hydropower Norway started generation of electricity from hydro power development 120 years ago. Over a period of 50 years a large number of small hydro was commissioned, and in 1929 we had more than 1300 stations in operation with output less than 1000 kW. The technology was purchased from Germany and England, and the power enhanced local production of furniture, cloths and other products, which benefited from new electrical machinery.
Micro- and mini hydropower number
Micro- and mini hydropower NVE supported projects : SKM project: Lessons learned by implementing micro- and mini hydro in Norway :Small hydro union, detailing issues derived from the SKM project and other new information :MGK project highlighted development in protected rivers, and micro - and mini hydropower influence on the local economy.
Micro- and mini hydropower NVE supported projects - SKM Results
The rules and regulations are difficult to understand A guide book is needed The different authorities (NVE, Directorate for Nature conservation, County and Municipality) should co-ordinate their control and licensing work better
Micro- and mini hydropower NVE supported projects - SKM Results NVE must implement the same tariff and policy in all the distribution companies NVE must secure that adequate information is available and regularly updated. It is a need to improve know-how and access to information on the electricity market
Micro- and mini hydropower NVE supported projects - SKM Results Need for improved financing pakages and know- how Need for technical guiding. 25% had experienced problems with intake, and 30% had bad experience with the electro- and mechanical equipment.
Micro- and mini hydropower NVE supported projects - MGK Results 62 possible hydropower plants are located The plants will have a total capacity between 5 and 15 MW, and produce GWh depending on release of compensation water Approximately 100% of electricity consumption in the Municipality could be covered
Micro- and mini hydropower NVE supported projects - MGK Results 13 of the 62 projects have serious environmental conflicts with the idea of “hydropower free watercourse” Total investment is approximately NOK 150 mill Construction activity over a period of 10 years will develop local business, and the need for support during the many years of operation can justify a local maintenance workshop.
Micro- and mini hydropower NVE supported projects - MGK Results Annual benefit for the municipality could be NOK 20 mill. Money saved are better than money earned. The hydropower activity is supplementary to farming, and because of need for few maintenance hours weekly, it allows the farmer to continue being a farmer. The scale factor is important and the largest plants have the best economic viability, but…. Own use of the power is the most important for the economy
Micro- and mini hydropower NVE supported projects - MGK what now? The Report is useful for the local area planning and energy planning The Report has been discussed in the Municipality, and they are now busy preparing an application for licence for 40 of the 62 projects in phase 1, and will present the rest in phase 2 next year when they feel the negative environmental impacts have been sorted out. Other surrounding Municipalities are now planning to embark on similar studies.
Micro- and mini hydropower 2002 n NVE has NOK 3 mill for improving the present situation, and by research and development enhance technical solutions and competence to reduce the worst cases of disasters
Micro- and mini hydropower 2002 NOK for supporting a test laboratory to clear the way for Norwegian certificates for turbine solutions. Also field test activities are included. NOK to support research on new intake technology NOK to support research on the use of “offshore drilling technologies” as a substitute to penstocks, and extending life of old penstocks by using inflatable rubber pipes.
Micro- and mini hydropower 2002 n NOK to support activities in the newly formed Small Hydro Association, which are of common interest. n NOK to improve an existing guide book on planning, financing, construction and operation of small hydro power plants n NOK to start the mapping of micro- and mini hydro resources in Norway by using GIS technology together with electronic hydrology maps and cost curves.
Micro- and mini hydropower 2002 n NOK for seminars and miscellaneous activities n We have 20 projects on a wait list with proposals: advanced tools for remote operation low cost turbine development low cost gates distance learning and more n The NVE activity will continue next year
Small Hydro less than 100 kW 6 kW farm hydro
Small Hydro less than 100 kW 6 kW farm hydro
Micro- and mini hydropower 2002 n The 6 kW farm plant was inaugurated in 1992, and has successfully been in operation for 10 years. n It has produced approximately kWh during these 10 years, and thus generated saving on the electricity bill for the farmer in the order of approximately NOK n The plant had a total construction cost in 1992 of NOK in addition to his own working hours, and the farmer received a lump sum from NVE of NOK because this was a test plant for micro hydro development.
