The development of a new adaptable short-term load forecasting (STLF) tool with the use of a neural network is introduced in this paper, to predict energy consumption in an industrial environment, by modeling industrial loads and creating a baseline for electricity consumption, using various data from industrial or other large consumers.

Adopting a circular economy approach requires new business models, multi-stakeholder engagement, and tailored financial models and mechanisms as core pillars. This paper examines the conditions needed to scale circular economy initiatives in Europe by analysing insights collected from the DECISO project and conducting a comparative analysis of 38 European projects. The study adopts a mixed methods approach that integrates an online stakeholder survey with inputs generated through participatory workshops and discussions of selected use cases. This combined approach is used to identify the main structural barriers limiting the maturity and investment readiness of circular economy projects, such as regulatory complexity, difficulties in accessing funding, and weak stakeholder dialogue mechanisms. The approach was also used for enabling factors that can support development of circular economy. Particular attention is given to the role of project development assistance, modular financing strategies, and de-risking tools, which are highlighted as crucial elements for supporting the technical and economic credibility of projects and attracting public and private investors. The article also identifies and addresses seven unresolved research gaps in the literature, including the lack of interoperable policy instruments, the absence of business models capable of integrating investor expectations, the paucity of integrated methodologies for assessing technical and economic regulatory feasibility, and the need for trust-building procedures. The findings suggest that the transition to a regenerative economy requires a systemic approach based on coherent policies, de-risking financial instruments, collaborative governance, and strategic technical support throughout the project development cycle.

This work presents the transition of Western Macedonia from a lignite-dominated energy model to a sustainable system based on renewable resources, with particular emphasis on the interlinked roles of policy, regulation, and financing. The analysis is centered on the utilization of biomass and residual waste for district heating applications, highlighting the contribution of the Just Transition Fund and the Greek Green Fund. The study also evaluates the regulatory and institutional frameworks that either support or hinder renewable energy deployment, while embedding the principles of circular economy and cross-border cooperation. The insights derived serve as a reference point for regions undergoing similar post-coal transitions, offering a comprehensive roadmap for sustainable energy integration underpinned by policy alignment and financial cohesion.

Initially, the paper involves a thorough analysis and documentation of international literature (research publications, global standards like IEEE, European standards like EN, experimental outcomes, etc.), along with existing studies conducted by the Hellenic Distribution Network Operator (HEDNO) on these topics. Subsequently, there will be a comparative assessment between the international findings and Greek standards and regulations regarding these matters. The final stage includes presenting a substantiated and detailed recommendation for each technical issue. Where feasible, an optimal proposal for fiber optic cable installation is developed for each case, ensuring technical compliance with all constraints.
