Storinum

Storinum is a decision and procurement platform for the renewable energy sector. We provide a single operating layer that connects technical feasibility with commercial reality, ensuring large-scale energy projects move from concept to operational asset without the typical delays or performance gaps. We remove the manual effort and ambiguity from energy investments through two core pillars: 1) Integrated Scenario Modelling: We translate complex site realities—grid constraints, load patterns, and infrastructure limits—into buildable pathways. Our platform synthesises vast market signals and technical data that are typically managed through time-consuming manual effort. By anchoring every option in verified data and deep market intelligence, we convert technical variables into clear commercial outcomes, ensuring projects are grounded in fact before capital is committed. 2) Structured Procurement: Storinum brings all vendor offers into a shared evaluation model where price, performance, and delivery timelines are directly comparable. This mechanics-driven approach reveals the true trade-offs in every bid. We ensure the final agreement isn't just a document, but a high-performance blueprint that locks in commercial value and delivery certainty before any contracts are signed. By providing a single framework for both analysis and acquisition, Storinum ensures that the system intended in the planning phase is exactly what is delivered on-site.

Favourable location to wealthy Scandinavian markets with (air)ports and ice-breaking ferries. Best wind and solar power conditions in the country, marking 7 GW of planned offshore wind capacity. Peak renewable generation feeding the hydrogen market, launching mobility decarbonization first. The target of energy independence is supported by the establishment of energy cooperatives, demand response, the use of local resources for energy production, and various storage solutions. Educational programs support key sectors of health tourism and promotion, aquaculture, small craft construction, the food industry, and smart energy solutions. The energy agency helps investors identify the best location, supply chain, partners, and energy sources by providing all soft-landing services, including permitting. The agency serves also businesses to increase energy efficiency and savings. The priority of the agency in the coming years is to help island municipalities decrease costs and emissions from their buildings. In addition, refurbishment advice is expected by apartment houses. Together archipelago stands for grid reinforcements allowing interconnection of renewables and attraction of energy-intensive investments (data centres, ammonia production, greenhouses, aquaculture). The energy agency links the region with other European islands.
