Platform

Run the whole portfolio from one place.

GPweb-Server is the operations platform that sits above your plants. Multi-plant, multi-tenant, in our cloud or on your own hardware.

There are many ways to feed it: our own dataloggers and remote controllers from small to large, smart meters, or data read remotely from other dataloggers — so most of what an operator needs is recorded automatically, then displayed, stored, reported, and tied straight into work orders.

Talk to us

One place, every plant

Each remote device sends up what it measured and what it was instructed to do. That is compared against forecast and simulated-performance data, to catch degradation or hidden faults before they surface. The system can also cross-check independent sources — inverter production figures against a smart meter reading the energy fed to the grid, or against settlement notes from sources like DAPEEP — so a bad meter, or energy lost somewhere it should not be, shows up rather than passing unnoticed.

The operations record writes itself

A curtailment instruction arrives from the grid operator. The platform opens an incident, files each change to the limit underneath it, and closes it when the limit is released. Same treatment for plant shutdowns, communication outages, an MV controller left in local, and breaker events — each one an entry with a start, an end and a duration. Nobody logs anything by hand; and where something cannot be detected automatically — a hole in the fence, say — an entry can still be added manually.

The commands that were correctly refused are on the record too. Plant in local for maintenance, a setpoint arrives anyway, the controller drops it as it should — and the drop is recorded: which command, what value, the exact time, and the mode that caused it. When someone asks why the plant did not respond on the fourteenth, that is a timestamped line instead of an argument.

And because those orders are on the record — with their limits, their durations and what the plant was producing when each one landed — the platform reports what the operator's instructions cost, per plant and per period. Most portfolios answer that question by hand, late, or not at all.

The logbook the field actually uses

Maintenance work lands in the same place as the automatic record. An entry opens, takes an assignee, moves to in-progress, and closes. Photos, reports and certificates attach to it, classified by document type, with validity dates on the ones that expire.

Who sees what

The organization tree holds companies, EPCs, departments and individual owners. Roles run from read-only viewer up to full administrator, granted per organization or per plant — and can be set to expire on a date. An O&M operator runs the portfolio; an owner sees his own plant and nothing else; an EPC keeps access through the warranty period and then it lapses on its own, without an admin having to remember. Each user works in English or Greek.

Our cloud or your rack

Hybrid edge-and-server, on purpose. Compliance and control stay on the box in the substation, where they keep working whether or not the platform is reachable — the platform is never in the path between the grid operator and your plant. The Server itself runs in our cloud or in your own rack: same build, your choice, and it can move later.

Common questions

Do we need a GPweb-Remote on every plant to use the platform?

No. You only need a Remote on very large plants, or where you must have DEDDIE remote control. Plants without one run monitoring-only, on the same data model and the same console. There are many ways to read the monitoring data — in many cases we read it directly from the inverters or dataloggers, remotely — and we also sell a very small, low-cost datalogger, GPweb-Monitor. Most portfolios start mixed and stay mixed for years, so the platform is built for that rather than against it.

We already have a monitoring portal from our inverter supplier. Why another one?

An inverter portal monitors that manufacturer's products only. A PV system with a substation (typically from about 250 kW) is inverters plus substation plus the grid operator's interface — and often inverters from more than one manufacturer. GPweb-Server holds all of it, including the relay, and it holds the control history the operator's instructions generate, which the inverter portal never sees. And GPweb is not only a monitoring tool: it does the operations management as well.

Can we run it on our own servers?

Yes. The Server runs in our cloud or on hardware you own and control. It is the same application either way, and the decision is reversible — some customers start hosted and move in-house when their IT policy catches up, or the other way round.

How does the incident record know what the grid operator sent?

The controller in the substation is the party that receives those commands, so it is the party that reports them. It publishes each command, each acknowledgement and each execution result upstream, and the platform assembles them into incidents. That is why the record is complete, rather than inferred from a production curve.

Does it handle net-metering as well as net-billing?

Both. Net-metering is closed to new applications but a large installed base still runs under it; net-billing covers everything new. The optimization problem — matching production to consumption across the settlement period — is the same, and Virtual NetBilling treats them the same way.

Can our field technicians and our clients use the same system?

That is what the role model is for. A technician sees the plants he works on and the entries assigned to him. An O&M operator sees the portfolio. Access is granted per organization or per plant.

How secure is your system?

Security has been designed into GPweb from the beginning. Energy infrastructure must be very well protected, and it is something many vendors neglect. Our systems work only over a VPN — automatically, by default — which makes intrusion very hard. All communication goes through a protected VPN, which also ensures that a breach in one place, should it ever happen, does not open the rest. There are no open ports on the remote systems to give an angle for intrusion. And the whole architecture has been independently audited.
