        Aid Programme for Solar Photovoltaics and Solar Thermal Energy

        As part of the Renewable Energy Action Plan 2000-2010, subsidies for both solar thermal (? 10.8 million) and solar photovoltaic (? 10.8 million) were provided in 2002. The subsidy was given to projects that started in 2002 and were completed before October 2003.

        …and energy-efficient equipment, as well as energy performance evaluation and advice services (required for undertaking refurbishment). The incentives take the form of grants, up to a maximum amount.


        These include subsidies for various renewable energy sources, such as solar thermal and solarphotovoltaic systems (30-50% of the cost up to a specific maximum amount), geothermal heat (40-50%), and biomass heaters (25-30%).

        Condesing boilers are also subsidised between EUR 80 and EUR 600.


        In addition, micro cogeneration fueled by renewable energy sources is subsidised up to 25%, while connection to a heating source fueled 75% by renewable energy…

        Policy Direction for Energy System Transformation Using AI

        This policy direction promotes the use of AI to transform Korea’s energy-system operation, planning and demand management. It focuses on AI-based forecasting, digital grid operation, distributed energy management, demand response, data-centre electricity-demand monitoring and regulatory reform for the AI power era. The agenda was discussed alongside the K-Grid Global Expansion Strategy at the 32nd Energy Committee, reflecting the government’s view that AI, electrification and grid expansion need to be managed together. It should be treated as a system digitalisation and power-sector flexibility policy rather than a general AI industrial policy.

        Battery storage is scaling up and taking on a larger system role

        Commentary As the result of falling costs and greater flexibility needs, battery storage is playing a growing role in power systems worldwide, acting as a “multi-tool” that can provide a range of critical system services at once. According to the latest data, the deployment of batteries expanded strongly in 2025 and broadened across markets – with rapid growth in countries such as Australia and Saudi Arabia, where storage is increasingly being used to support the integration of rising shares of variable renewables.In regions that have been at the forefront of renewable integration and battery deployment, batteries now play an…

        ECOSTAND 071-2:2017: Minimum Energy Performance Standards for air conditioning products

        It establishes minimum energy performance standards for air conditioners with cooling capacity below 20 kW. The regulation defines efficiency requirements and testing procedures for AC units used for space cooling in residential and commercial buildings, aiming to reduce electricity consumption from cooling equipment and improve the efficiency of air-conditioning technologies placed on the market.

        Guidelines on State aid for climate, environmental protection and energy 2022

        …on State aid for climate, environmental protection and energy 2022 are part of the broader EU regulatory framework under Article 107(3)(c) of the Treaty on the Functioning of the European Union. This article permits state aid that supports the development of specific economic activities or regions, provided it does not significantly distort competition within the EU. The guidelines ensure that state aid measures align with EU policies, particularly the European Green Deal, which aims for a climate-neutral Europe by 2050. They establish the criteria the European Commission uses to assess the compatibility of state aid measures with…
