2 We are hydropower The history of Pöyry Energy GmbH is founded in Austria upon more than 50 years of experience in engineering and power plant construction. Our special know-how has been applied to many of the country s hydropower plants. You too can take advantage of this expertise in the implementation of your small hydropower projects! Austria is qualified to energy generation of hydropower like no other country in Europe. Besides the large rivers of the Danube, Inn, Mur and Drau, hundreds of municipalities are home to streams and bodies of water that are ideal for electricity production. Experience since 1959 Pöyry Austria has been dealing with this issue since its founding. Our engineers have been bringing the expertise acquired since 1959 into the construction of many Austrian projects for hydropower plants. Today, our experts support hydropower projects out of Salzburg and Vienna maybe they ll soon be overseeing yours.

4 Always at the cutting edge Ever since the Austrian Viktor Kaplan put his first turbine into operation in 1919, a great many revolutionary developments have taken place in power plant and turbine construction. We haven t missed a single one and co-designed many. However, amid this spirit of i nnovation, we never lose sight of the essential: the user-friendliness, cost-efficiency and durability of your plants. Technically speaking, we at Pöyry are always at the cutting edge. Our engineers continuously deal with the latest developments in building technology, in turbine construction, in electrical engineering and automation. Innovation & proven technology However, due to our 50 years of experience, we know that the potential of innovative new solutions can only be fully exploited if they are intelligently integrated within proven technology. What we wish to achieve for our customers is the utmost availability, reliability and operating safety, as well as efficiency. Alongside offering a consulting service for technical implementation, there are many other areas in which our employees can support you with their expertise: They know what needs to be taken into account in environmental impact assessments, are well-versed in hydrological surveys or make the economic calculations concerning the profitability of your project. Regardless of what you are planning, we have the expertise to jointly implement your project with you.

This guarantees an optimal design of weir plant, water intake, Works waterway and other System components. In order to achieve the best results, our recommended technical solutions also differ according to the project concerned. Your advantage: our proposals are independent of the supplier. 5

6 All from a single source Our portfolio offers the entire range of services that you need for the successful realisation of your small hydropower plant projects: from the support in the initial planning and feasibility studies right through to construction, site supervision and the turnkey handover of the plant. You decide to what extent you wish to engage as we handle the rest reliable, custom-fit and on schedule. 6

7 Preliminary studies Feasibility studies Approval design Tender Design Project construction Preliminary studies A great deal has to be taken into consideration before the decision to construct a small hydropower plant is made: Where is the region s greatest potential? Which sites are suitable? And what impact does the construction have on flood protection, groundwater and water ecology? All of these questions can be answered by means of appropriate preliminary studies. For example, we compile so-called master plans (capability studies on a large scale) and carry out both site and variant analysis. Feasibility studies If the preliminary studies show that the construction of a small hydropower plant is sensible, we are able to build upon this to clarify all issues relating to feasibility. We conduct hydrological and geological tests, make energy economical calculations and design the framework for construction methods and civil engineering. Approval Design Prior to the start of construction, a serious hurdle needs to be overcome: the approval by authorities. In this case, it is good to have a company at ones side who is familiar with all elements of law and water, construction and electricity industry, as well as the preservation of nature. Of course, our experts also know how the project description must be designed, what has to be considered in specifications on execution of construction work and construction traffic, and which infrastructure facilities must in no way be disremebered by the operating company. Tender Design It is also not a problem should you decide not to collaborate with us on the construction. We file the tender documents for you for acceptance of tender, and supply you with all of the general, commercial and technical specifications for the proceeding. Once the developers proposals are available, you can utilize our wealth of experience in this area and have them assessed by us. In addition we re happy to accompany you by your contract negotiations. Project execution There are several variants in our proposal for the construction of your plant. One variant is that we only carry out the engineering. We then take care of the detailed design for the civil works and and the electrical and mechanical engineering, the project management, the site management and site supervision, as well as the contractual management. However, you can commission us with just the design, procurement and installation of electrical equipment. We then ensure that the power connection to the grid and the automation function perfectly. As a logical consequence, we also offer the complete construction of small hydropower plants. You thus receive a plant that is at the cutting edge of technology, in which the budget fits, that is commissioned on schedule, in which the maintenance costs are low and the operational availability is high. From the initial preliminary studies right through to the commissioning of the plant, our team of experts offers the entire range of services in individual project areas or as a Comprehensive package. 7

8 Investments with a future The construction or revitalisation of a small hydropower plant is not just about opting for an environmentally friendly method to generate power. It is also tied in with considerable investments. Our special funding offer from the federal and state governments enable costs to be reduced. 8

9 To ensure that your project stands on a solid economic foundation, we support you in the energy efficiency calculations and compile an initial rough cost estimate. In addition, there is also the possibility to apply for special funding. Both the federal and some state governments support operators of small hydropower plants in the construction and revitalisation of their plants. Federal government funding is regulated via the Eco Electricity Act ( 12a). This falls under the jurisdiction of the managing body of Ökostrom AG (OeMAG). Operators of small hydropower plants of up to a maximum of 10 MW may apply here for investment grants of 1,500 Euro per KW or up to 30 % of the eligible investment costs (see illustration). Federal state funding Alongside the State funding via OeMAG, the federal state (Bundesländer) of Lower Austria, Upper Austria and Styria have issued their own funding programmes. Lower Austria, for example, increases the State funding by a further 25 % upon approval. Upper Austria grants an increase of 25 % of investment costs (maximum 50,000 Euro per plant/ operator) to plants with a potential capacity of up to 1 MW, and Styria funds already the planning phase for consulting services of external service providers. Anyone planning a small hydropower plant is therefore advised to find out about funding possibilities in advance.
