Haven Power
• Electricity Supplier to serve small to medium sized business customers
and large Industrial & Commercial customers
• Launched in 2006, now employing 350 staff with a turnover in excess of
£250 million
The initial problem:
• The IT estate has grown rapidly with the business, with the technology
infrastructure struggling to keep up with demand
• Mixed virtualisation and a combination of on-site, off-site servers
• Technology working in a reactive basis to support growth

Requirements
• Provision of a solution quickly, to provide more robust disaster
recovery.
• Flexibility to change as the onsite solutions / change programme
developed and advanced.
• To provide a supporting solution for the entire Business
Continuity Plan – not just IT Disaster recovery.

What has changed over 3.5 years ?
The solution has had to support:
• Internal rationalisation, consolidation and virtualisation of platforms
• Opening of a new office wing, closing of temporary office location and relocation of
200 people
• A significant change programme introducing a new billing and registration platform
• Significant growth of the business and critical dependency on IT
• Existing Production Hardware coming to end of life

Lessons to Share
• Continuous training – with attrition rates and continuous development, training and
education is essential. (Skills are in demand)
• Architecture Definitions for capacity planning regularly include costs models for
annual operating (hours run per day) and storage costs.
• As current infrastructure comes to end of life, reviewing options for hardware refresh /
transition to the cloud. Cost model becoming harder to ignore as the business has
grown.
• Continuous Improvement - working with suppliers to ensure they support our
infrastructure and application needs moving forward.
