Software near the grid is judged on what it cannot break
In energy, the question is rarely whether a feature is possible. It is whether the thing you are connecting to can be touched at all, who signs off, and what happens to operations if the integration misbehaves at the wrong moment.
FusionHit builds energy and utility software with senior engineers across Latin America who have worked with meter and telemetry data, device protocols and read-only integrations into systems nobody wants to disturb. They work US Central and Eastern hours, so a change window, an interconnection deadline or an incident is handled inside your day.
\ Energy systems we build
The systems our clients bring us most often, each one built around the data, the devices and the operating constraints behind them.
EV charging platforms
Charge point management, sessions, pricing and roaming, plus the operational view for when a site goes offline.
DER and storage management
Solar, storage and flexible load monitored and dispatched, with the safety and interconnection rules respected.
Metering data and meter to cash
Interval data from the head end through validation and estimation to the bill, at the volume AMI actually produces.
Demand response and flexibility
Programs, enrollment, events and settlement for the loads you can actually move.
Field and asset operations
Work orders, inspections and asset history for crews who are outdoors, often without a signal.
Operational data integration
Read-only paths out of SCADA, historians and metering systems into the analytics and applications above them.
Forecasting and analytics
Load, generation and price forecasting, plus the reporting your operations and commercial teams argue about.
Legacy modernization
Moving a utility or energy system off an unsupported stack, with history intact and operations undisturbed.
The energy companies we build software for
Regulated utilities, developers and technology companies answer to different people. That changes what gets built.
Investor-owned utilities
Work around operational systems, under a regulator and an audit calendar.
Municipal utilities and co-ops
Smaller teams carrying the same obligations, usually with older systems and no spare capacity.
EV charging providers
Networks that have to stay up and settle correctly across sites you do not physically control.
Renewable developers and IPPs
Monitoring and performance across a portfolio, where availability is revenue.
Retail energy providers
Billing, enrollment and customer systems in a market with thin margins.
Energy technology companies
Product companies that need senior engineering capacity on a roadmap their customers depend on.
What connecting to grid and field systems actually involves
Every vendor says they integrate with existing infrastructure. In this industry the question is what you are allowed to touch, and that is what decides the timeline.
Getting operational data out without becoming a risk to operations.
A read-only path agreed with your operations team, usually through a historian or a data diode style boundary rather than a direct connection, and a design your security people approve before anything is installed.
Interval reads from the head end through validation, estimation and editing to billing.
A pipeline sized for the real read volume, handling of late and missing reads as normal cases, and an audit trail that shows how an estimated value was produced.
Chargers, inverters, controllers and loggers that speak their own languages.
OCPP for charging, Modbus and OPC UA for equipment, MQTT for telemetry from the edge, and buffering so a lost connection costs a delay rather than a gap in the record.
Solar, storage and flexible load that has to behave the way the interconnection agreement says.
Following the profiles your utility requires, testing against them, and keeping evidence of the behaviour because someone will eventually ask for it.
Keeping operational networks separated from everything above them.
Traffic in one direction wherever possible, a defined segment for the integration, and change windows planned with operations instead of announced to them.
Your own obligations about vendors who touch systems near the grid.
Named engineers under your access policy, work inside your cloud accounts, change records available for audit, and access removed the same day someone rolls off.

How an energy build runs
What it takes to build, by system
Vendors answer this with 'it depends'. Here is what it depends on, by the kind of system, so you arrive at the first call knowing what to expect.
2-4 months
Number of device types and protocols, quality of vendor documentation, and whether an edge component is needed.
5-9 months
Site and connector count, pricing and roaming, payment handling, and the operational tooling behind it.
4-7 months
Asset types, control requirements, interconnection rules to follow, and the alerting operations needs.
4-8 months
Read volume, head end systems, validation and estimation rules, and what billing expects downstream.
4-6 months
Offline behaviour, asset hierarchy, integrations with work and asset systems, and crew rollout.
6-12 months
Feature parity, data and history migration, and running both systems in parallel through a change window.

DER or storage monitoring

Why energy companies build with FusionHit
-
Read-only until proven otherwise
Anything near operations is designed as a read-only path, agreed with your operations and security people before it is built.
-
Inside your change window
Engineers on US Central and Eastern time, so a cutover, an interconnection deadline or an incident is handled during your working day.
-
Senior engineering talent
Vetted nearshore engineers with production experience in metering, device integration and operational data.
-
Integrated partnership
One delivery lead accountable to you, working in your tools and reporting in writing every week.

Three ways to work with us
Pick the model that fits how your team runs. Plenty of clients start with one and move to another as the roadmap grows.
Staff augmentation
Senior engineers added to your existing team, under your direction. Best when you have a technical lead and need capacity or a specific skill.
Dedicated development teams
A stable team that works only on your product, with a lead on our side. Best when you want a whole workstream owned without hiring a manager for it.
Software development outsourcing
A defined scope delivered end to end under our management, for a fixed price and date. Best when the scope is clear and you want one number and one date.
