“…To this end, Barthelmie et al (1996) and Holttinen (2005) suggest that Danish wind power peaks in the afternoon and the effect is more pronounced in summers. On the other hand, He et al (2012) and Huber et al (2014) show that German wind power tends to peak at night and also in summer afternoons.…”

Although variable renewable energy (VRE) technologies with zero marginal costs decrease electricity prices, the literature is inconclusive about how the resulting shift in the supply curves impacts price volatility. Because the flexibility to respond to high peak and low offpeak prices is crucial for demand-response applications and may compensate for the losses of conventional generators caused by lower average prices, there is a need to understand how the penetration of VRE affects volatility. In this paper, we build distributed lag models with Danish and German data to estimate the impact of VRE generation on electricity price volatility. We find that in Denmark wind power decreases the daily volatility of prices by flattening the hourly price profile, but in Germany it increases the volatility because it has a stronger impact on off-peak prices. Our analysis suggests that access to flexible generation capacity and wind power generation patterns contribute to these differing impacts. Meanwhile, solar power decreases price volatility in Germany. By contrast, the weekly volatility of prices increases in both areas due to the intermittency of VRE. Thus, policy measures for facilitating the integration of VRE should be tailored to such region-specific patterns.

“…The second module of eLOAD, dealing with DR modelling, aims to to smooth the net load, which is defined as the system load less the generation of renewable energy sources. A smoothed net load ensures efficient use of existing electricity generation and grid infrastructure, increased operational security as well as a reduced need for investments in new electricity generation and transportation assets [50], [51].…”

National demand for electricity follows a regular and predictable daily pattern. This pattern is set to change due to efficiency improvements, de-industrialisation and electrification of heat and transport. These changes are independent of renewable infeed and are not well understood: contemporary studies assume that electricity load curves will retain their current shape, scaling equally in all hours. Changes to this shape will profoundly affect the electricity industry: increasing the requirements for flexible and peaking capacity, and reducing asset utilisation and profitability. This paper explores the evolution of load curves to 2050 in Germany and Britain: two countries undergoing radically different energy transformations. It reviews recent developments in Europe's electricity demand, and introduces two models for synthesising future hourly load curves: eLOAD and DESSTinEE. Both models are applied to a decarbonisation scenario for 2050, and consistently show peak loads increasing by about 23% points above the change in annual demand, to 103 GW in Germany and 92 GW in Britain. Sensitivities around electrification show that a million extra heat pumps or electric vehicles add up to 1.5 GW to peak demand.The structure and shape of the future load curves are analysed, and impacts on the national electricity systems are drawn.

“…Huber et al (2014) conclude that there is a dramatic increase in flexibility requirements when the share of renewables of annual electricity consumption exceeds 30%. However, renewable generation has a negative impact on power prices due to its zero marginal costs and prevents the deployment of high-cost flexible plants (Würzburg et al, 2013).…”

How much is enough? Optimal support payments in a renewable-rich power system

The large-scale deployment of intermittent renewable energy sources may cause substantial power imbalance. Together with the transmission grid congestion caused by the remoteness of these sources from load centers, this creates a need for fast-adjusting conventional capacity such as gas-fired plants. However, these plants have become unprofitable because of lower power prices due to the zero marginal costs of renewables. Consequently, policymakers are proposing new measures for mitigating balancing costs and securing supply. In this paper, we take the perspective of the regulator to assess the effectiveness of support payments to flexible generators. Using data on the German power system, we implement a bi-level programming model, which shows that such payments for gas-fired plants in southern Germany reduce balancing costs and can be used as part of policy to integrate renewable energy.
