The short version

  • Each has a real cost: Emerson Ovation nothing about the cost is published, and the licence is a minority of the total; engineering, I/O hardware and commissioning commonly exceed it, so a budget built from a software quote will be wrong by a large multiple.; EcoStruxure Geo SCADA Expert the ClearSCADA name is retired, so the large body of documentation, forum answers and integrator experience under that name is increasingly stale and does not always match current behaviour.
  • They diverge on capability: Emerson Ovation covers Power application libraries, EcoStruxure Geo SCADA Expert covers Point-banded server licence.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Emerson Ovation

  • Nothing about the cost is published, and the licence is a minority of the total; engineering, I/O hardware and commissioning commonly exceed it, so a budget built from a software quote will be wrong by a large multiple.
  • Ovation is power and water specific, so a group operating both power stations and chemical plants will end up running Ovation alongside DeltaV or a third-party DCS and paying for two engineering skill sets.
  • The annual support and subscription contract is effectively mandatory: without it you lose access to security patches, which for a NERC CIP regulated asset is not a decision you can defer.
  • Replacement is bounded by outage windows rather than by budget, so a decision to leave Ovation typically takes multiple years and cannot be reversed cheaply once started.
  • Third-party engineering capability is much thinner than for Rockwell or Siemens platforms, so you are largely dependent on Emerson or a small partner pool for changes, and their day rates set the cost of every future modification.

EcoStruxure Geo SCADA Expert

  • The ClearSCADA name is retired, so the large body of documentation, forum answers and integrator experience under that name is increasingly stale and does not always match current behaviour.
  • Licensing is point-banded and client-counted with nothing published, and discount depends on your existing entitlement, so a first-time buyer negotiates from a weaker position than an incumbent renewing.
  • The free development mode is capped at 1,000 points and two hours of runtime, which is enough to prototype a screen but not enough to load-test a realistic network before you commit.
  • It is a Windows Server product; there is no Linux server option, so the operating system licensing, patching cadence and hardening burden come with the platform whether you want them or not.
  • Schneider has repeatedly rebranded and repositioned this line, from Control Microsystems to ClearSCADA to EcoStruxure Geo SCADA Expert, which makes long-horizon roadmap commitments hard to trust for a system a utility expects to run for fifteen years.

What is Emerson Ovation best used for?
Emerson Ovation is most often used for replacing an end-of-life control system on a coal or gas unit during a planned outage, where the vendor must supply turbine control as well as plant control, a municipal water authority standardising treatment plant control across several sites under one nerc-adjacent security regime, an ipp wanting the dcs and the safety instrumented system engineered in the same tool rather than integrated across two vendors, hydro operators needing iec 61850 and dnp3 into a control system that also runs the balance of plant. Of those, replacing an end-of-life control system on a coal or gas unit during a planned outage, where the vendor must supply turbine control as well as plant control and a municipal water authority standardising treatment plant control across several sites under one nerc-adjacent security regime are not what EcoStruxure Geo SCADA Expert is typically brought in for.

Answered from the vendors’ own pages

Emerson Ovation: Is Ovation the same as DeltaV?

No. Ovation targets power generation and water; DeltaV targets chemicals, life sciences and refining. They are separate products with separate engineering tools and separate support organisations.

EcoStruxure Geo SCADA Expert: Can I still buy ClearSCADA?

No. The product is sold as EcoStruxure Geo SCADA Expert. ClearSCADA is a retired name and current quotes will use the new one.

Emerson Ovation: Can I get a price without talking to Emerson?

No. There is no published price list, no trial and no self-service configurator. Every Ovation number comes through Emerson or a certified partner.

EcoStruxure Geo SCADA Expert: How is the server licensed?

By point count, in bands starting around 250 points and scaling to over a million on a single server. Clients are licensed on top, individually or in bundles.

Emerson Ovation: Does Ovation 4.0 mean I can stop buying Emerson hardware?

No. The software-defined architecture virtualises controllers, but the I/O and field interfaces are still Emerson hardware and are still the bulk of the equipment cost.

EcoStruxure Geo SCADA Expert: Is there a way to test it for free?

Yes, unlicensed development mode runs up to 1,000 points for two hours at a time. That is a prototyping tool, not a pilot.

Emerson Ovation: What decides the price?

Controller count, I/O point count and the number of operator workstations, plus the engineering hours to configure the control logic for your plant.

EcoStruxure Geo SCADA Expert: Is Geo SCADA the same as AVEVA Plant SCADA?

No. Plant SCADA is the former Citect product for plant-floor supervisory control. Geo SCADA is the former ClearSCADA product for distributed telemetry. Different codebases, different problems.
