Energy networks and storage

Costain plays a significant role in safely delivering the energy infrastructure that will satisfy the UK’s future needs.

The demand for new power generation and transmission assets continues to increase. We need to replace ageing power stations and grid networks, and prepare for an increase in electricity demand over future decades. We must also ensure that we have a safe and flexible gas network, capable of providing the heat and energy that our economy needs.

What might this mean?

  • New capital investments including flexible small-scale gas generation, renewables and new nuclear generation
  • Investing in making existing power stations cleaner
  • Upgrading and expanding transmission and distribution infrastructure – creating more flexibility.

The Costain solution

We bring an asset lifecycle perspective to energy infrastructure projects (ideal for a RIIO environment - a performance-based model introduced by Ofgem to set price controls to ensure consumers pay a fair price for this investment) supported by seamless transitions between project phases, and shortened lead times and outages.

Our power sector team offers

  • ‘Right first time’ projects that minimise downtime, delivered safely and sustainably   
  • Innovative solutions, suppliers and processes to meet regulatory or economic challenges
  • Flexible solutions and forms of contract that allow operations to change with the market 
  • System integration and optimisation (e.g. Building Information Modelling [BIM], programme management)
  • Collaboration leader and facilitator for large-scale, long-term solutions
  • Partner for life – asset management, construction, operations & maintenance and decommissioning and disposal at the end of an asset’s life
  • Depth of talent to deliver what customers need 
  • A commitment to bring new talent into the energy industry, via graduate programmes and apprenticeships – including offering job share opportunities to fast track experience for customer and Costain people.
