On the seabed

2017 Operational Report

Our 2017 Offshore Wind Operational Report tracks progress in the development of the UK's offshore wind resources over the year, the busiest yet for the sector.

The report builds a picture of a maturing technology, which supplied the electricity needs of 5.3 million homes in 2017 (around 20% of the UK total) and helped reduce the UK's CO2 emissions by 8.6million tonnes.

It is an example of The Crown Estate’s work to collaborate with the offshore wind sector and stakeholders to share data and best practice, helping to unlock value offshore.

2017 Marine Aggregates Capability & Portfolio Report

The Crown Estate owns almost all of the sand and gravel resources lying off of the coast of England, Wales and Northern Ireland and we award and manage commercial agreements for companies to extract it.

This document is designed to help planning officers in local authorities understand the contribution that marine aggregates can make, by identifying offshore sources and providing information on supply routes. 

How collaboration is creating value

The Marine Data Exchange, established by The Crown Estate in 2013, is now one of the biggest sources of marine data in the world, providing a platform to manage and share offshore survey data collected by our customers throughout the lifetime of their projects. 

Chelsea Bradbury, Marine Data Advisor, reflects on the important role of this resource, in encouraging collaboration, reducing costs, and ultimately de-risking investment offshore.

Offshore wind energy map

Take a look at our unique, interactive offshore wind electricity map, refreshed hourly, which shows the estimated total electricity being generated by offshore wind around the UK, as well as it’s percentage share of the UK’s total electricity generation, at any one time.  You can also see data for each individual windfarms such as site capacity, operator, number of turbines, and current output, as well as current wind speed and direction.
