Empowering the EV Charging Economy: How S44 Energy is Supporting Operators in a Post-Subsidy Market

As federal EV subsidies slow and programs like NEVI hit pause, many in the industry are sounding alarms. Headlines speculate about falling demand. Automakers recalibrate production goals. Skeptics say the electric future is faltering.

At S44 Energy, we see something different.

We see the market beginning to mature — not retreat. It’s the end of the start-up phase and the beginning of a new chapter defined by real-world performance, business fundamentals, and open-market innovation. This is where the EV industry shifts from being propped up by policy to thriving through competition and customer value.

To help usher in this next era, we’re introducing a new platform purpose-built for charge point operators: TopazEV — a Charge Station Management System (CSMS) designed to unlock growth, flexibility, and long-term profitability.

A Market Built on Value, Not Mandates

The early-stage rollout of EV infrastructure needed public investment to take root. But now that EVs are becoming mainstream, the rules of the game are changing. Operators, retailers, and utilities must find new ways to compete — and win — based on service quality, uptime, and revenue opportunity.

TopazEV was created to meet this moment. It gives operators more control, more margin, and more options to scale charging networks that serve both their customers and their bottom line.

Here’s how:

Revenue Retention

With traditional SaaS solutions, operators often lose a cut of every charging session to transaction fees or roaming markups. TopazEV flips that dynamic by offering a flat-fee model. CPOs keep 100% of their session revenue, unlocking better unit economics from day one.

Technology Independence

Operators shouldn’t be boxed in by someone else’s roadmap. Built on open standards like OCPP 1.6 and 2.0.1, OCPI, and ISO 15118, TopazEV supports full integration flexibility and is available as either a hosted platform or a self-managed deployment. That means operators can design the stack that suits their business model — not the other way around.

Reliability That Drives Demand

Roughly 20% of charging attempts still fail in the U.S., hurting consumer confidence. TopazEV equips operators with real-time network insights, fault monitoring, and plug-and-charge capabilities to increase uptime. Better reliability leads to happier drivers, stronger usage, and more profitable operations.

An Open Future, Built by Operators

At S44 Energy, we’ve long championed the role of open-source technology in accelerating EV adoption. We built CitrineOS, the most widely deployed open-source OCPP 2.0.1 stack, now a Linux Foundation Energy project. That same ethos fuels TopazEV, which we’ve developed as an Open-as-a-Service (OaaS) platform — combining the transparency and interoperability of open-source with the ease of a managed service.

This approach ensures CPOs, retailers, and fleet operators have access to modern tools without sacrificing flexibility or control.

The Opportunity Ahead

The U.S. is at a crossroads. While other nations accelerate EV deployment, the U.S. has the potential to lead — not just in vehicle adoption but in the systems that power them. That means investing in energy resilience, scaling smart infrastructure, and building an ecosystem where charging operators can thrive.

TopazEV is more than a software product. It’s part of a larger commitment to a free and competitive EV economy. Because when operators succeed, the entire industry moves forward — faster, stronger, and more sustainably.

TopazEV is available now — and we’re just getting started.
