        Energy System Resilience

        Lessons learned from Ukraine Ensuring energy security encompasses both long-term and short-term dimensions. The long-term dimension involves securing sufficient infrastructure investment and diverse supply sources. The short-term dimension – resilience – focuses on systems’ ability to cope with events exceeding standard planning conditions. Since Russia’s full-scale invasion in 2022, Ukraine has worked to protect its energy sector and to increase its ability to withstand and rapidly recover from Russia’s attacks on its energy infrastructure. The report explores the lessons that Ukraine has been learning as it works to bolster system resilience and identifies measures that…

        Planned Energy Efficiency Certificates

        As part of Frances Energy Bill, the government planned to put in place a system of tradable "white certificates" for energy efficiency. Suppliers of energy (electricity, gas, heating oil, LPG, heat, refrigeration) would be required to meet government-mandated targets for energy savings achieved through the suppliers residential and tertiary customers.

        Integrating Distributed Energy Resources in China

        Lessons from international experience Like no other country in the world, the People’s Republic of China (hereafter, “China”) is witnessing rapid growth in distributed energy resources (DERs), including rooftop solar photovoltaics, battery storage and electric vehicle (EV) chargers. As China advances towards its carbon peaking and neutrality goals, these resources offer a unique opportunity to support a more flexible, efficient and resilient power system, provided their integration is well-managed.This report analyses recent trends in DER deployment across China and highlights the emerging challenges their growth poses for power system planning and operation, calling for renewed attention to…

        Uganda

        In 2019, Uganda’s energy mix was dominated by fuel wood and charcoal followed by a small share of oil products. The country produces electricity mainly from hydroelectric plants. Between 2017 and 2019, electrification outpaced population growth in Uganda. However in 2020, less than 5% of the population had access to clean cooking.
        The Electricity Connection Policy was introduced in 2018 with the ambition of increasing Uganda’s electricity access to 60 percent by 2027 through connection subsidies for consumers located close to the existing network. About 300,000 households and businesses have received free electricity connections, benefiting 1.5…

        New Zealand

        New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including a strong renewable resource base. New Zealand already has a low-emissions electricity system, with over 80% of electricity coming from renewable sources. The key challenge will be to decarbonise other end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors. Notably, the transport sector accounts for the highest share of emissions and is almost entirely dependent on oil while…

        Brazil

        Brazil’s energy policies measure up well against the world’s most urgent energy challenges. Access to electricity across the country is almost universal and renewables meet almost 45% of primary energy demand, making Brazil’s energy sector one of the least carbon-intensive in the world. Total primary energy demand has doubled in Brazil since 1990, led by strong growth in electricity consumption and in demand for transport fuels on the back of robust economic growth and a burgeoning middle class.
        Large hydropower plants account for around 80% of domestic electricity generation, making the Brazilian electricity mix one of…

        South Africa

        Coal is the mainstay of the South African energy system, meeting around 70% of installed power generation capacity. The 2019 Integrated Resource Plan however sets out a long-term diversification of the power mix by 2030 and moves towards lightening the carbon footprint of the energy sector while meeting growing energy demand and ensuring a socio-economically just transition. While the options to diversify the country's electricity mix appear diverse, the affordability of electricity supply looms as a key concern and a potential constraint on diversification. The structure of consumption and of spending on electricity is skewed towards higher…
