    Economic solutions for the integration of volatile renewable electricity generation aredecisive for a socially supported energy transition. So-called energy-flexible factories can adapt theirelectricity consumption process efficiently to power generation. These adaptions can support thesystem balance and counteract local network bottlenecks. Within part of the model regionAugsburg, a research and demonstration area of a federal research project, the potential, obstacles,effects, and opportunities of the energy-flexible factory were considered holistically. Exemplaryflexibilization measures of industrial companies were identified and modeled. Simulations wereperformed to analyze these measures in supply scenarios with advanced expansion of fluctuatingrenewable electricity generation . The simulations demonstrate that industrial energy flexibility canmake a positive contribution to regional energy balancing, thus enabling the integration of morevolatile renewable electricity generation. Based on these fundamentals, profiles for regional marketmechanisms for energy flexibility were investigated and elaborated. The associated environmentaladditional expenses of the companies for the implementation of the flexibility measures wereidentified in a life-cycle assessment, with the result that the negative effects are mitigated by theincreased share of renewable energy. Therefore, from a technical perspective, energy-flexiblefactories can make a significant contribution to a sustainable energy system without greaterenvironmental impact. In terms of a holistic approach, a network of actors from science, industry,associations, and civil society organizations was established and actively collaborated in atransdisciplinary work process. Using design-thinking methods, profiles of stakeholders in theregion, as well as their mutual interactions and interests, were created. This resulted in requirementsfor the development of suitable business models and reduced regulatory barriers.

    Given the increasingly volatile prices on the power markets, it becomes economically more and more important for companies to develop and realize flexible strategies for energy consumption. A steady adaption of production processes which considers current power prices can take place on several levels of the automation pyramid, where each level has its own characteristics and requirements. In this paper, we present an optimization architecture based on an IT-platform which meets the challenges of complex multilayered production processes. We introduce layer-specific optimization strategies as well as an associated information flow, which facilitates creating holistic and well-coordinated optimizations.

    The growing share of renewable energy generation based on fluctuating wind and solar energy sources is increasingly challenging in terms of power grid stability. Industrial demand-side response presents a promising way to balance energy supply and consumption. For this, energy demand is flexibly adapted based on external incentives. Thus, companies can economically benefit and at the same time contribute to reducing greenhouse gas emissions. However, there are currently some major obstacles that impede industrial companies from taking part in the energy markets. A broad specification analysis systematically dismantles the existing barriers. On this foundation, a new end-to-end ecosystem of an energy synchronization platform is introduced. It consists of a business-individual company-side platform, where suitable services for energy-oriented manufacturing are offered. In addition, one market-side platform is established as a mediating service broker, which connects the companies to, e.g., third party service providers, energy suppliers, aggregators, and energy markets. The ecosystems aim at preventing vendor lock-in and providing a flexible solution, relying on open standards and offering an integrated solution through an end-to-end energy flexibility data model. In this article, the resulting functionalities are discussed and the remaining deficits outlined.

    Industrial demand response uses a multitude of energy flexibility measures. Their planning and control requires various production IT systems. A widely accepted approach to classify these inhouse IT systems are the levels of the automation pyramid in companies. This paper broadens the scope of this concept to overcome the limitation to companies' (virtual) borders by including required IT systems that refine and monetarize a company's energy flexibility, e.g. energy markets, aggregators, etc. Therefore, a holistic approach for the classification of functionalities for industrial demand response across companies and energy markets is developed and applied exemplarily.
