LOADSHIFT Oberwart
An optimized load shift for electricity, heating and cooling is to be conducted via the development and the living-lab test operation of an all encompassing building- and user-effective energy management in the urban test area of Oberwart. This will enable the integration of Renewables (particularly biomass and solar energy) by increasing direct user quota and Grid Parity without sponsorship, expensive storage applications and grid investments, and do so in an efficient and economical manner.
Initial Situation
The availability of energy based upon decentralized energy sources in combination with an intelligent energy supply system that forces the collaboration of producers can increase the direct user quota by bringing together complementing user load profiles and thus facilitate an optimized (partial) self-sufficiency without costly storage applications. Therefore, optimized load management facilitates the economic integration of Renewables (biomass, PV, solar thermal) by achieving grid parity without sponsorship. Any necessary grid- infeed is reduced, losses and expensive grid investments are minimized. Bringing together the partial areas of intelligent renewable energy production and targeted load shifts, or Demand Side Management (DSM) via complementing urban users under the present general framework, are the starting point of this R&D project and shall be achieved by the development and the test operations of overall building energy management with central command. From Burgenland’s point of view, Oberwart as the second largest city of the region is particularly suitable. With regard to its power supply, Burgenland will be financially self-sufficient by the year 2013 (for example 10x higher PV share than the rest of Austria). The integration of fluctuating energy sources (wind in particular) will be more and more difficult for Burgenland. Furthermore, Oberwart boasts a mentionable heat- and electricity production gained from biomass; a great portion of this energy production is presently financed by sponsored green electricity rates, but it must be marketed directly via smart energy rates in the process. Such rates are to be supported correspondingly by Demand-Side Management Systems on the part of the infrastructure operator. Therefore, the region’s power grid is looking for cost-effective solutions for the integration of Renewables, while load shifts represent the most promising option. As a result, a suitable model region is needed, which is represented by Oberwart. After comprehensive analysis, an optimal (complementing) power load profile is available here, i.e. an ideal consumer combination in a manageable urban area. This makes it possible to realize a comprehensive demonstration while the level of complexity is still manageable.
Problem
Based upon the aforementioned initial situation and the state-of-the art, comprehensive consideration and interdisciplinary optimization are required to realize an overall building/housing load- and energy management. This innovative starting point is complex and requires answers to many new questions. Particularly the integration of an overall building energy exchange in superordinate grids leads to new (interface-) problems:
Economic aspect: How can advantageous conditions be spread across all operators? How is the load shift “priced”? Who is responsible for operations, maintenance and repairs?
Legal aspect: Who is responsible for overall operations? What standards and norms are up-to-date and/or must be reconsidered?
Technological aspect: To date there is no technological standard/no agreement between home technology, energy management, IKT and users and/or a building-relevant or superordinate system. What technical solutions are feasible and how do those have to be developed or adapted? Can defined interfaces be established for all areas?
Security aspect: How are maintenance work or inspections managed? What protective mechanisms are in place and who is authorized to apply those? How can the risk of unintentional grid isolation be prevented?
Social aspect: How can the usage be influenced, yet the quality of life/ processes be maintained at the same level?
Goals
In light of the initial situation as well as the urban vision and the available implementation concepts, the following main goal for LOADSHIFT Oberwart emerges: development and living-lab test operation of a an overall building- and user-(integrated) urban load- and energy-management (EM) system for electricity, cooling and heating with focus on the creation of interface compatibility for all building-related technical components and systems (complex interlacing between home technology, energy management, ICT and users). This should be achieved by the following demonstration projects in a living lab:
- Load shifts in the regional heating grid
- DSM/ load shift through building and/or object automation (primary schools, middle schools, model housing complexes, industrial facilities, agricultural operations, water-supply utilities, waste-water purification plants, community lighting systems);
- Interface-compatible energy-control systems;
- Realization of business models adapted to load shifts and integration of Renewables.
Planned results:
- Realistic efforts toward solutions to implement overall building-energy management systems for electricity, cooling and heating with focus on load shift and integration of Renewables (biomass and solar energy)
- Finding a basis for the state of the art of an overall building EM
- Solutions for the production of interfaces with superordinate grid/system-developed/adapted, tested and verified components and software systems of overall building EM test applications: (1) demonstration of 10% peak load reduction in the regional heating grid (currently approx.. 15 MW) despite regional heating expansion to 3.1 GWh (=10% of the current regional heating demand); (2) demonstration of 20% peak load reduction in energy (currently approx. 7MW) despite PV expansion by 1.87 GWh (=6% of the current energy demand); (3) reduction by approx. 1.182 t CO2 , or approximately 3% of emissions.
- Project-related legal aspects and business models
- Well-founded, experientially documented statements about experience/obstacles/success factors/potentials/usability and recommended actions and conclusions from “active” buildings as an integral part of an energy system with parallel view of varying energy-usage forms and users/buildings
