Superior End-to-End Project Delivery
Multi-vendor coordination is often what slows a project down, but Stem's Project Delivery service removes that problem entirely. One team owns every phase, from initial design through commercial operation, so there's no handoff between parties, no waiting on someone else to resolve an issue, and no ambiguity about who's accountable when something needs to get fixed.
That accountability starts before a project ever reaches your site. Every deployment is factory pre-configured and pre-tested at Stem's own certified production facility in Colorado, then supported by regional engineering hubs in the Americas, EMEA, and APAC – so the same rigorous process runs behind every project, in whatever market you're operating in, and gets you to commercial operation faster.
Technical Capabilities Proven at Scale
Full Visibility from Day-One
All solutions configured, tested, and verified by technical experts and engineers in Stem's Longmont Assembly before shipment ensures data from BESS, solar and battery PCS, meteorological stations, and balance of plant equipment, all accessible the same day your system goes live. Sub-second polling means nothing gets missed.
Dedicated Project Management
One accountable project manager, from kick-off to commissioning. We coordinate the details so your solar and energy storage projects stay on schedule and go live correctly.
Technical Cybersecurity Expertise
We apply defense-in-depth across PowerTrack and site controls, with network segmentation, role-based access, encrypted communications, and managed patching. Our program is aligned to ISO 27001 for information security management, IEC 62443 for industrial control system security, and NERC CIP for bulk electric system protection.
Regulatory Reporting that Runs Itself
Stem preconfigures automated submissions and compliance management across SGIP, CleanPeaks, and other regional programs. Standardized formatting and submission protocols work across every site and every market you operate in.
Controls Engineers
Our controls engineers design and configure the systems that make solar and storage plants behave as one. They build EMS, PPC, and SCADA integrations, tune control modes, and model plant response to meet utility and grid code requirements. Backed by deep experience across inverters, batteries, meters, and protocols, they deliver controls that perform on day one and stay reliable over the life of the asset.
Commissioning Support
Hands-on engineers who get your plant from installed to online. We test, validate, and troubleshoot every system so you reach commissioning and PTO with confidence.
