in the UK
Iberdrola, through its subsidiary ScottishPower, is one of the largest energy companies in the UK. Its activity focuses on electricity networks, renewable energy and the energy retail sector.
Iberdrola's UK subsidiary, ScottishPower, is one of the UK’s largest energy companies and operates across electricity networks, renewables and the energy retail sector. It is spearheading the UK’s green energy transition; from building the clean renewable power needed to reduce reliance on dirty, volatile fossil fuels, to rewiring the electricity grid for the future and supporting customers with clean technology in their homes and businesses. It was the first integrated energy company in the United Kingdom to produce 100% green electricity.
In line with Iberdrola's strategy to upweight investment in A rated countries with stable regulatory environments, the company will invest £24billion to 2028 unlocking more clean, green renewable power, alongside investing in a major rewiring of Britain to more efficiently transport it around the country. Significantly reducing the UK’s reliance on fossil fuels and boosting energy security.
ScottishPower's main business lines
ScottishPower divides its activity into three main business lines:
Electricity networks: Through its SP Energy Networks and SP Electricity North West brands, ScottishPower is now the second largest distribution network operator in the UK, delivering electricity to around 12 million people across a network spanning more than 170,000 kilometers.
SP Energy Networks distributes and connects electricity across Merseyside, Cheshire and North Shropshire (England) and North Wales, as well as central and southern Scotland. SP Electricity North West distributes electricity across the north-west of England including Manchester and the Lake District. It was acquired by Iberdrola in August 2024 and unveiled its new name and visual identity as part of ScottishPower in 2025.
SP Energy Networks also owns and operates the high voltage transmission network across central southern Scotland. It has plans to invest up to £12bn to 2031 via RIIO-T3 in a major rewiring of Britain to support electrification.
ScottishPower Renewables: with more almost 3,100 MW of installed capacity, it has 40 onshore and two offshore wind farms in operation. It is also in the process of building the East Anglia Three offshore wind farm, the second largest in the world with an investment of almost £4 billion, as well as East Anglia Two. Together with the already operational East Anglia One, they will form East Anglia Hub, an ambitious project which will see up to 3.9GW of power generated off the east coast of the UK.
ScottishPower Customer: With 4.2m customers, ScottishPower is one of the UK’s largest retail energy suppliers, selling electricity and gas alongside supporting customers to install smart solutions like EV charging, heat pumps and domestic solar to households across the country.
ScottishPower also supports decarbonisation through green hydrogen
