Introduction
As global demand for renewable energy accelerates, energy storage manufacturers face unprecedented pressure to improve production efficiency, streamline supply chains, and operate on a digital foundation capable of supporting rapid scale. ESS Inc., a leader in long-duration iron flow battery technology, recognized early that digital transformation was essential to meet increasing market demand and operational complexity. By partnering with NexInfo to implement and continuously optimize Oracle Cloud applications, ESS embarked on a multi-year modernization journey that transformed their financial operations, manufacturing workflows, and enterprise-wide visibility. NexInfo’s Oracle Managed Services played a critical role in stabilizing, enhancing, and expanding ESS’s cloud ecosystem to support significant growth from 2017 through 2024.
About ESS Inc.
ESS Inc. (NYSE: GWH) is one of the most innovative companies in the clean energy sector, manufacturing long-duration iron flow batteries for commercial and utility-scale applications. Using earth-abundant materials such as iron, salt, and water, ESS provides safe, affordable, and sustainable energy storage solutions that support grid stability and renewable energy adoption. With a growing global footprint and a rapidly expanding customer base, ESS required an enterprise platform capable of supporting the full lifecycle of manufacturing—from supply chain planning and production through order fulfillment and financial consolidation.
By 2024, ESS had expanded its user base by over 200%, reflecting significant organizational growth and escalating operational demands. To sustain this momentum, the company needed a scalable technology infrastructure with continuous Managed Services support to ensure reliability, agility, and strategic optimization.
Challenges Faced Before Transformation
Before adopting Oracle Cloud applications, ESS encountered challenges common among fast-growing manufacturing organizations. Their legacy systems lacked real-time visibility across supply chain operations, inventory levels, production workflows, and financial processes. As manufacturing complexity increased, the need for a tightly integrated ERP system became critical. ESS also required enterprise planning capabilities, predictive financial modeling, and integrated service operations to support field deployments and post-installation support.
The company’s rapid growth created additional pressures, including scalability constraints, manual reconciliation processes, disconnected operational data, and limited forecasting intelligence. ESS needed not only a modernized ERP ecosystem but also a reliable Managed Services partner to maintain system performance, manage releases, support enhancements, and ensure long-term operational continuity.
Oracle Cloud Modules Implemented
ESS implemented an extensive suite of Oracle Cloud applications covering Finance, Supply Chain, Planning, Manufacturing, Inventory, Procurement, Costing, Order Management, Subscription Management, CX, Field Service, Maintenance, HCM, BI, Integrations, and EPM.
This broad adoption enabled ESS to create a unified, cloud-first operational framework that connected engineering, manufacturing, finance, operations, and customer support into a single digital ecosystem.
Solutions Implemented by NexInfo
NexInfo supported ESS through a phased, multi-year Oracle Cloud rollout beginning in 2017 and continuing through major expansions in 2021, 2022, 2023, 2024, and 2025. NexInfo’s implementation strategy focused on aligning cloud capabilities with ESS’s aggressive growth trajectory. The team designed integrated workflows for production planning, procurement, order orchestration, subscription billing, workforce management, financial consolidation, and predictive planning.
A defining factor in this engagement was NexInfo’s Managed Services, which ensured stability, scalability, and continuous optimization as ESS expanded domestically and globally. NexInfo provided 24/7 AMS support, overseeing issue resolution, system enhancements, quarterly update validation, integration monitoring, performance optimization, and process improvements. The AMS team ensured ESS remained release-ready for every Oracle quarterly update—a critical requirement given ESS’s extensive module footprint.
NexInfo also supported ESS with ongoing global expansion initiatives, including footprint expansions from 2021 to 2023, CX enhancements in both sales and field service, EPM Planning deployment, predictive cash forecasting, and PLM expansion. Their continuous AMS involvement ensured that new functionalities were adopted effectively and aligned with operational readiness.
Benefits Achieved
With Oracle Cloud ERP, SCM, CX, and EPM fully deployed and supported by NexInfo’s Managed Services, ESS achieved enterprise-wide digital transformation. The company now benefits from real-time inventory visibility, accurate supply chain planning, optimized manufacturing workflows, and connected financial reporting. Predictive analytics and scenario modeling enhanced decision-making accuracy, while automation reduced manual work and improved operational throughput.
ESS’s customer service operations also improved significantly with integrated field service management, enabling better scheduling, dispatch, and resolution tracking. Subscription and order management improvements accelerated revenue recognition and strengthened customer lifecycle management.
Most importantly, NexInfo’s Managed Services ensured uninterrupted performance, rapid issue resolution, continuous enhancement delivery, and the ability to scale the system in parallel with ESS’s explosive growth. This has allowed ESS to focus on innovation and market expansion without being constrained by technology limitations.
