The tender was completed under the new NESO entity with Public procurement organisation number (PPON) PHQL-5234-MWWV
National Grid Electricity System Operator Limited (NGESO), a legally separate business
within the National Grid Group, is the electricity system operator for Great Britain. NGESO
moves electricity around the system to keep homes and businesses supplied with the
energy they need 24/7.

(NESO) and become owned by the UK government. Where in this notice we refer to
NGESO, this should be understood as also including NESO after the change is taken
place.
The Digital, Data and Technology (DD&T) organisation within NGESO provides the
sourcing capabilities, roles and skills required to achieve NGESO digital deliverables.
To support the role of the National Energy System Operator (NGESO), we are looking to
put in place a digital and data capabilities framework, encompassing the following lots:
• Lot 1: All Digital & Data
• Lot 2: Data & AI
• Lot 3: Security
