AlternaFuture has been a multidisciplinary research project in Hydrocen to investigate the potential of extreme upgrading of existing hydropower system with a positive effect on the environmental conditions. The project is a desk study and is carried out through developing future scenarios of an extreme upgrading of an existing hydropower system, to create potential for new innovations and solutions from the multidisciplinary scientists within the project. The existing hydropower system in the Mandal river has been applied as a case-study, where the current situation has been the baseline for developing alterative future scenarios and evaluating the economic and ecological results.

Flomdempingstjenester i utvidet miljødesign - Beskrivelse og uttesting av system for klassifisering av flomdempingspotensial i regulerte vassdrag

Bendik Hansen, Atle Harby

This report goes through the method that was developed for the classification of flood dampening services from hydropower reservoirs in CEDREN. The method shows potential flood dampening on an overview level by analyzing readily available data about reservoir sizes, yearly runoff, reservoir filling through the year, drawdown capacity, and the relationship between degree of regulation and flood peak dampening.

Multimarket modelling
Mari Haugen, Linn Emelie Schäffer

This report documents the work done in task 1 of WP3 in HydroCen on multimarket price modelling. The focus of the work has been to simulate spot prices and prices for procurement of reserve capacity using different modelling tools and functionality. We will in this report describe the differences between the models and functionality that have been used, compare price results and discuss challenges in this study and for future work on this topic. All the models and functionality used in this project are developed and maintained by SINTEF. The results illustrate the complexity in forecasting prices for procuring reserve capacity and the impact on spot prices. Furthermore, we find that the PriMod models provide good estimates for prices of providing reserves, while the EMPS functionality not performed that well on our test cases. The report documents nicely how SINTEFs models can be used together and highlights some important experiences to consider when conducting studies like this

 Modelling batteries
Linn Emelie Schäffer

The report documents a test of how pumped storage functionality can be used to model batteries in SINTEFs
long-term models. Firstly, optimal operation of a battery in a price taker setting is simulated using the ProdRisk
model. The exogenous prices are taken from the Low Emission Scenario [3]. This first test was mainly done to
build competence on the problem of modelling batteries. The results show that it functions very well being
aware of the assumptions of the model, the most important being prices known for the whole week. In the
second test, two batteries were put into our Low Emission dataset of Northern Europe 2030, with one battery
in Germany and one UK. The dataset was simulated using the EMPSW model that uses formal optimization on
individual plant level for the weekly marked clearing problem. EMPSW model gives reasonable results and show
that batteries with relative short-term storage capacity can considerably reduce the number of price spikes. As
for ProdRisk, EMPS also assumes everything known for the whole the week. In addition, the testes identified
the weekly end value setting of battery storage as an improvement area. Especially, when the batteries are put
into areas without regular hydro storages.

Environmental Constraints in Seasonal Hydropower Scheduling Survey and Feasibility. Arild Helseth, SINTEF Energi AS. The work documented in this report has been carried out in project WP3.4 in the HydroCen research center. We have surveyed the need for improved modelling of environmental and tech-nical constraints related to operational hydropower scheduling software. The results have been processed and summarized, and we have selected the two major types of constraints that seems the most relevant for this project. The two constraint types are described and their possible in-clusions in the stochastic dual dynamic programming (SDDP) algorithm are assessed. 

Towards environmental design in hydropower reservoirs - Developing a handbook for mitigation measures in regulated lakes. Ingeborg P. Helland, Stein I. Johnsen, Antti P. Eloranta The aim of this report is to investigate the feasibility of developing a handbook for environmental design related to fish in reservoirs, similar to the one for salmon rivers.

Rekreasjonsinteresser i utvidet miljødesign: demovassdrag Nea. Margrete Skår og Berit Köhler. Denne rapporten gjør rede for rekreasjonsinteresser knyttet til det valgte demovassdraget, Nea i Selbu og Tydal kommune.

How are environmental measures realized in European hydropower? A case study of Austria, Switzerland and Sweden. Berit Köhler & Audun Ruud. This report explores how environmental measures are realized in European hydropower production, how they are financed, and how trade‐offs between hydropower production, environmental restoration and value creation are considered.

Power Price Scenarios -  Results from the Reference scenario and the Low Emission scenario. Linn Emelie Schäffer and Ingeborg Graabak. The aim of the research described in this report is to show and quantify variation in power prices in Northern Europe in 2030. The background for this study is the need for reduction of green-house-gases (GHG) emissions and EUs policy for transforming the energy system and in particular the power system to low carbon systems.

Utvidet miljødesign: Ulike metoder for kunnskapsutvikling om rekreasjonsinteresser og landskapsopplevelse i og langs regulerte elver og vassdrag. Margrete Skår og Berit Köhler. Denne rapporten har som hovedformål å danne grunnlag for utprøving av aktuelle metoder i vårt framtidige arbeid i HydroCen 4.3, for kunnskapsutvikling om feltet rekreasjonsinteresser og landskapsopplevelse.

Future Market Structures  and Prices - Workshop summary. Linn Emelie Schäffer. The purpose of the workshop was to improve the participants understanding of the value of Norwegian hydropower, the expected changes in value and the main drivers for change. This include, but is not limited to, the development of prices, services and market structures.
