The Project Realizing Value from Electricity Markets with Local Smart Electric Thermal Storage Technology (RealValue) is a European Union funded project that analyzes the impact of the implementation of local small-scale power-to-heat storages predominantly in domestic buildings across Ireland, Germany, and Latvia. While there are studies that focus on large power storage projects, there are hardly any that take a local and decentralized view. This gap is filled by the RealValue project.

The project revolves around local small-scale power-to-heat storages (SETS). SETS are modern and efficient electric heaters. However, information and communication features distinguish SETS from ordinary electric heaters.  For example, SETS are capable to react to electricity prices, charge when electricity is cheap and save households money. Since households cannot react to cheap electricity prices at the power exchange, companies that have such access may bundle households with SETS together and share the profits with said households.

The task of bundling households with SETS together is non-trivial. Therefore, the RealValue project aims to provide 1,250 households in Ireland, Germany, and Latvia with SETS in order to test how best to aggregate the electricity demand for space heating. In addition to technical difficulties, the project also analyzes consumer behavior – with a special focus on whether SETS allow households to reduce their electricity spending. Apart from benefits to individual household, large parts of RealValue pursue the question whether local small-scale power-to-heat storage benefits the electricity system as a whole employing modelling techniques. In addition, RealValue also analyzes regulatory issues introducing electricity storage into a system as complex as the European electricity market.

Workshop 2015

Forum on Flexibility Options in the Electricity and Heat Markets

 Berlin, 21 September 2015

DIW Berlin, Mohrenstrasse 58, Schumpeter Hall

The aim of our expert forum is to explore improvement potentials and interactions in storage and renewable energy technologies, demand side management, e-mobility, and energy efficient housing stock. To this end, we have invited experts share their expertise on their respective targets regarding technological and cost potentials, drivers and risk. Each presenter will have about 12 minutes to give the audience the broad strokes of his or her area of expertise in a nutshell. The remaining session time is reserved for questions and answers as well as general discussion.

The objective of the workshop is to broaden the understanding of the technology options and to discuss future scenarios. The outcome of the workshop will also be used to guide the modelling activities of the overall project, in particular the development of an integrated energy model for electricity and space heating sectors that is intended to be set up as a free, fully disclosed, open-source model.

09.30-10.00   Registration & Coffee

10.00-10.15   Welcoming remarks: Prof. Karsten Neuhoff, Deutsches Institut für Wirtschaftsforschung

10.15-10.45   Opening Presentation: Prof. Mark O’Malley, University College Dublin

10.45-11.00   Coffee Break

11.15-12.00   Electricity storage (power-to-power)

A variety of battery types as well as hydro storage are being considered to allow for storage of power at different scale and time frames. We will provide a structured overview of the different opportunities emerging, and discuss the key drivers that will impact their relative importance as well as competitiveness with other flexibility options.

12.00-12.45   Electricity to heat conversion (power-to-heat)

Instead of conserving electricity by means of pump-storage, electricity can also be transformed into heat. These heat storages could absorb electricity when production exceeds demand, for example when renewable electricity production is high. To model the potentials for small electric thermal storage (SETS) is at the heart of this project.

12.45 – 13.45                Lunch Break

13.45 – 14.30                Electric-mobility

In addition to heat conversion, electro-mobility could have a potentially large impact on the electricity market. Batteries in electric vehicles could be charged at times of surplus electricity from intermittent renewable electricity production. There is also the possibility of discharging batteries at times of high electricity demand into the electricity grid. This would depend on the cost of a battery and the number of times it can be discharged before it has to be replaced.

14.30 – 15.15                Demand-side measures

Instead of storing and discharging electricity, there is the possibility to shift or shed parts of the electric load. For example, select consumers could be disconnected from the grid to lower peak electricity demand. To make a noticeable impact on overall electricity consumption, these electricity consumers would usually have to be bundled together.

15.15 – 15.30                Coffee break

15.30 – 16.15                Thermal efficiency of buildings and energy conservation

In addition to technological changes in electricity and heat generation, there are also advances with respect to thermal efficiency of buildings that might have a large impact on the overall demand, but might also impact the technology choice for energy conservation.

Presenter 2: Prof. Thomas Bednar

16.15 – 17.45                Cross-cutting session

After reviewing individual flexibility options in the electricity and heat market, such as power-to-power or power-to-heat storage, the cross-cutting session will open up the discussion and take on questions regarding the expected relative costs as and potential interaction of the individual technologies. The aim is to provide a broader perspective on scenarios of future flexibility provision.
