IDNO for adoption of HH4 Data Centre

Eclipse Power have been appointed by NTT as the IDNO for the adoption of the contestable grid connection works feeding their new HH4 Data Centre in Hemel Hempstead.

The IT space which totals 9,600 sqm will provide a secure, high availability environment solution for housing IT and network systems, offering a maximum of 24MW critical IT load to the initial development,

As the IDNO, we are providing a 132kV 60MW capacity grid connection. The facility is metered at 132kV via Eclipse Power’s on-site 132kV switchgear, and will allow additional load growth and or connection to further NTT DC facilities.

IDNO working with ICPs

We will be working closely with the appointed ICP to develop an effective adoptable design that meets the Data Centres specific requirements’. As an IDNO. we are not constrained by onerous and prescriptive standards and the solution will not be ‘over-engineered’ as it sometimes the case with the DNO.

Eclipse Power are adopting ABB’s Hybrid PASS M0 (Plug and Switch System) 132kV switchgear, which contains a complete switchgear bay in a single module, helping to minimise the on-site substation footprint.

The commercial solution which we provided also ensures NTT can benefit from lower Use of System charges in the first 5 years following energisation. We achieve this by managing the ‘ramping-up’ of agreed capacity over time to meet their expected growth plans, whilst still providing the flexibility of making more capacity available, more speedily if required.

NTT Global working with Eclipse Power Networks

Thomas Georgi, Head of Power Management, NTT Global said:

The Global Data Centres EMEA division of NTT Ltd. found Eclipse Power Networks engaging, helpful and knowledgeable from the first interaction.
Eclipse Power Networks helped us consider various connection and metering options towards our investment case. We look forward to working with Eclipse Power Networks as our IDNO on this prestigious 132kV connected data centre and will consider them again for any future sites we develop in the UK.
