The UK's renewable energy generation in 2023 will exceed that of natural gas, most of which will come from wind power

With the increasing role of renewable energy in the UK's electricity supply, the UK has taken another step towards the independence of new energy. According to the data, in the winter of 2022, the electricity generated by renewable energy in the UK exceeded the electricity generated by natural gas, which is enough to provide electricity for every British household throughout the winter.
According to the data of the UK non-profit organization Energy and Climate Intelligence Center, between October 1 and February 24, 2022, the UK's wind, hydro and solar power generation capacity will reach 46 TWh, more than 45 TWh of natural gas power generation capacity. Renewable energy power generation in the UK accounts for 38% of the country's power generation, almost equal to 40% of natural gas power generation, which also makes the UK a net exporter of electricity for the first time since 2010.
Most of Britain's clean energy comes from wind power generation, which is the most efficient in winter when the wind is strong.
Increase the contribution of renewable energy!
According to the MARTIN analysis of Hengfengyou Electric, in the winter of 2022, renewable energy power generation has replaced more than one third of the UK's annual demand for natural gas power generation, and wind power generation occupies a more important position.
If there is no renewable energy for power generation, the UK will have to burn more natural gas, which may increase its net import of natural gas by more than 22%, including natural gas imported through pipelines.
The energy director of the UK Energy and Climate Intelligence Centre said: "We see that the old power system has been replaced by the new power system, and renewable energy has become the pillar and is increasingly replacing natural gas."
He said: "The development speed of new energy and battery energy storage is faster than expected, which improves the energy security of the UK and makes us less affected by the international natural gas market.".
The CEO of the British Energy Industry Association said that "we must do everything possible" to encourage and accelerate investment in low-carbon energy. She added that the analysis of the Energy and Climate Intelligence Center confirmed that the local renewable energy power generation has made an increasing contribution to British households and businesses.
Committed to achieving greater energy independence.
How does the rapid development of new energy in the UK benefit our power transmission and distribution enterprises?
Evan, the electrical engineer of Hengfengyou Electric, shares with you the importance of wind power step-up transformer for wind power generation. Wind power step-up transformer is particularly important for wind power generation.
The construction of wind power stations has a high demand for wind power step-up transformers. Each wind turbine generator unit needs to be equipped with a wind box-type substation. The power station also needs dry-type step-up transformer, dry-type isolation transformer and dry-type reactor for grid-connected transmission.
Due to the unstable output power of wind power generation, the no-load and load losses of dry-type transformers are high, and the energy efficiency requirements of dry-type transformers are high (the transformers produced by Hengfengyou Electric can fully meet the requirements of Tier 2 of the EcoDesign Directive of the European Union on energy efficiency of transformers); The layout of wind power stations is relatively scattered and remote, and dry-type transformers need to have the characteristics of low failure rate and maintenance-free; The wind explosion-proof step-up transformer needs to withstand the wind and sand environment, especially the offshore wind explosion-proof transformer, and also needs to be able to withstand the long-term corrosion of sea salt, which requires high reliability.
Qingdao Hengfengyou Electric Group, an electrical enterprise with power transmission and distribution products as its main business, is the designated supplier for the world's top 500 enterprises. The main products are power transformers, medium and low voltage switchgear, distribution boards, circuit breakers, transmission towers, wires and cables, new energy and other transmission and distribution equipment. It has been successfully sold to more than 50 countries around the world. https://www.hengfengyou.com ； info@hengfengyou.com ；
