Hitachi MDMS
Hitachi’s Meter Data Management System (MDMS) turns massive smart-meter streams into reliable, real-time business value. Proven at scale in Japan and beyond — cloud-native, serverless, and AI-ready — MDMS from Hitachi enables utilities to accelerate smart metering journey, improve operational resilience, and unlock smart-meter data monetization.Â
Hitachi MDMS — An Overview
Hitachi MDMS ingests, validates, stores and processes data from millions of meters across the grid. Built on a distributed processing framework, the platform supports high-throughput transformations (30-minute register values and shorter), secure seamless system integration with other systems e.g. HES, CIS, ADMS, DRMS and flexible deployment (on-premises, cloud, cloud-migration).
Utilities face mounting pressure from rapid smart meter adoption, evolving regulations, and the need for real-time data processing. Traditional systems struggle with scalability, transparency, and operational complexity, leading to inefficiencies and higher costs.
Hitachi MDMS addresses these challenges with a future-ready, flexible architecture that ensures high-speed processing, seamless integration, and simplified operations.
Flexibility to handle energy regulatory changes
MDMS needs to have flexibility to handle frequent changes in the regulatory and business environment that utilities are facing
Rapid data growth for next-generation smart meters (5-min intervals, billions of records)
High-speed processing architecture for huge amount of smart meters data including net usage calculation for 5-minute register value and advanced use of smart meters data and sudden intensive processing requests
Reduces significant maintenance workload related to OS/middleware EoL, license renewal, and server replacement
Smart meter data monetization
By converting high-resolution consumption data into insights, digital services, and grid optimization products
Agile operational support by enabling agentic AI based on-demand assistance to streamlines operations and accelerates issue resolution
Our Solution – Flexibility by Design
Hitachi MDMS is purpose-built to help utilities thrive in a dynamic energy landscape. It combines enterprise-grade reliability with next-generation agility, enabling fast adaptation to evolving data volumes, regulations, and business models.
Flexible Implementation
Modular, microservices-based architecture allows each MDMS function to scale or upgrade independently. `Open APIs and User-Own Coding (UOC) simplify integration and ensure future readiness.
Flexible Operation Support
Agentic AI (Chat Bot) guiding operators through exception analysis, data correction, and audit traceability.
Flexible Infrastructure
Deployed on AWS 'native' hyperscale architecture with Hitachi’s distributed processing framework, the system scales effortlessly millions of smart meters.
Flexible Development Process
Agile and CI/CD-enabled delivery accelerates rollout of new features, regulatory updates, and analytics use cases.
Key Features
Smart Meter Daily Summary Dashboards
At-a-glance operational insight with flexible visualization and drill-down analytics summarizing asset status, between meter, feeder, or region-level. Charts and widgets can be personalized by role — operations, business, or energy analysis — ensuring every user sees the most relevant KPIs.
Smart Meters List
A unified and flexible view of all connected smart meters.The Smart Meters List allows operators to search, filter, recollection and manage millions of devices with ease. Built with flexible design, simplified asset visibility and faster meter management through intuitive UI could be achieved.
