“…They study the effect of different electricity price scenarios on HPP revenue under climate change and conclude for a single emission scenario that HPP revenue losses due to the projected reduction of 25% of water inflow by the end of the century can largely be mitigated through HPP flexibility. Another interesting approach is the work of François et al (2014) who propose to adapt HPP management rules to future conditions based on an analysis of the marginal value of stored water; with such an analysis, the best equilibrium between the water resources and electricity demand can be identified for future scenarios.…”

“…How this integration might develop in the near future remains unclear (Beaudin et al, 2010;Yang and Jackson, 2011) especially in light of economic and environmental considerations (Gullberg et al, 2014;Kloess and Zach, 2014). Research into how the integration might be affected by the spatio-temporal variability of climate related energy (water, wind, sun) and by climate change is in its early stages (François et al, 2014), and much of this research is difficult to access, either in grey literature or in not publicly available reports .…”

Hydropower is a key energy source in almost all world regions, it fuels social and economic development, ensures electricity security and is a pillar for renewable electricity production. But hydropower and its environmental impacts are vulnerable to climate change. This discussion of model-based climate change impact assessments and underlying modelling assumptions will help decision makers and scientists analyzing existing studies and identifying the most urgent open questions. Rooted in hydrological uncertainty analysis, this discussion focuses on the importance of local factors and on modelling uncertainties for a critical view on our ability to project future hydropower production in different world regions.

“…The magnitudes of the environmental constraints ϕ, considered in this study, and ρ, evaluated in [1], were selected to cover a wide range of values. As in [44], ϕ is the average of its seasonal values (ϕ [1][2][3][4][5][6][7][8][9][10][11][12][13] , ϕ [14][15][16][17][18][19][20][21][22][23][24][25][26] , ϕ [27][28][29][30][31][32][33][34][35][36][37][38][39] and ϕ [40][41][42][43][44][45][46][47][48][49]…”

The Influence of Environmental Constraints on the Water Value

Abstract:The establishment of more severe hydrological environmental constraints, usually as seasonal minimum flows (ϕ) and maximum ramping rates (ρ), on hydropower operation is a growing trend. This paper presents a study on the influence of ϕ and ρ on the water values (WV) of a real hydropower plant that participates in the Spanish day-ahead electricity market. For this purpose, a master-slave algorithm, based on stochastic dynamic programming (SDP) and deterministic mixed integer linear programming (DMILP), is used on a real hydropower plant. The master module, based on SDP, has a yearly planning period with weekly time steps and considers three state variables: stored water volume in the reservoir at the beginning of each week; weekly water inflow; and average weekly energy price. The slave module, based on DMILP, has a weekly planning period with hourly time steps and considers many features of the hydropower plant operation, such as: start-up costs, evaporation, wear and tear costs, etc. The results indicate that WV of a hydropower plant are very sensitive to the presence of these constraints; ϕ especially during the wettest season and ρ during the driest one. As the severity of ϕ and ρ increase, WV increase and decrease, respectively.

“…). The multiscale space-time variability of VRE complicates their integration into the electricity networks [3][4][5]. In any energy mix scenario with high shares of VRE, temporal variations of the production would not exactly match those of the load, leading to a succession of over-and under-production periods and, in turn to a risk…”

Impact of Climate Change on Combined Solar and Run-of-River Power in Northern Italy

et al. 2018

Moving towards energy systems with high variable renewable energy shares requires a good understanding of the impacts of climate change on the energy penetration. To do so, most prior impact studies have considered climate projections available from Global Circulation Models (GCMs). Other studies apply sensitivity analyses on the climate variables that drive the system behavior to inform how much the system changes due to climate change. In the present work, we apply the Decision Scaling approach, a framework merging these two approaches, for analyzing a renewables-only scenario for the electric system of Northern Italy where the main renewable sources are solar and hydropower. Decision Scaling explores the system sensibility to a range of future plausible climate states. GCM projections are considered to estimate probabilities of the future climate states. We focus on the likely future energy mix within the region (25% of solar photovoltaic and 75% of hydropower). We also carry out a sensitivity analysis according to the storage capacity. The results show that run-of-the river power generation from this Alpine area is expected to increase although the average inflow decreases under climate change. They also show that the penetration rate is expected to increase for systems with storage capacity less than one month of average load and inversely for higher storage capacity.
