The client’s AMI platform was becoming a constraint on performance, cost, and future operating models – rather than an enabler of digital transformation.
Client Context
A large power utility managing a significant AMI estate, facing pressure to reduce operating costs and evaluate outsourced communications models.
Ask / Requirement
The power sector client engaged SIS to assess and transform its Advanced Metering Infrastructure (AMI) to address performance, reliability, and operating cost issues, and to determine whether an outsourced communications model was viable while maintaining security across AMI, IT, and OT environments.
Key decisions on outsourcing, communications, and security lacked a single architectural view – increasing long-term costs and operational risk.
What We Delivered
SIS delivered a current-state AMI architecture assessment and a risk-informed digital transformation roadmap, using TOGAF and SABSA, covering HES, meters, communications, data, and security.
The outcome provided the client with a definitive architectural reference – a single source of truth – to guide transformation decisions, evaluate outsourcing options, and manage security across AMI, IT, and OT environments with confidence.
Outcome
The client was able to make an informed, risk-evidenced decision on the outsourcing question, with clear transformation options and cost implications identified. Architecture and security decisions that had previously stalled could now proceed from a shared reference point.
