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.; Landis+Gyr Gridstream the platform depends on Landis+Gyr metering hardware, including electric, gas and water meters plus communication network devices, rather than being sold as software alone
  • They diverge on capability: Emerson Ovation covers Power application libraries, Landis+Gyr Gridstream covers Advanced metering infrastructure.
  • 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.

Landis+Gyr Gridstream

  • The platform depends on Landis+Gyr metering hardware, including electric, gas and water meters plus communication network devices, rather than being sold as software alone
  • No price, licensing model or subscription term is published on the solutions pages; the site offers only a contact form and a distributor finder
  • Deployment, integration and ongoing optimisation are sold as separate Lifecycle Services rather than included

Questions people ask

Is Emerson Ovation or Landis+Gyr Gridstream better?
Neither clearly leads. Emerson Ovation starts at On request and Landis+Gyr Gridstream at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Emerson Ovation or Landis+Gyr Gridstream?
Emerson Ovation starts at On request and Landis+Gyr Gridstream at On request.
Does Emerson Ovation or Landis+Gyr Gridstream run on more platforms?
Emerson Ovation runs on Windows, On-premise. Landis+Gyr Gridstream runs on Web, Api.
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 Landis+Gyr Gridstream is typically brought in for.
What can Emerson Ovation do that Landis+Gyr Gridstream cannot?
Emerson Ovation covers Power application libraries, Ovation SIS, Embedded historian, NERC CIP tooling. Landis+Gyr Gridstream covers Advanced metering infrastructure, Real-time meter data, Grid edge analytics, Distribution automation.

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.

Landis+Gyr Gridstream: How much does Landis+Gyr GridStream cost?

Landis+Gyr does not publish pricing on their website. Contact Landis+Gyr directly through their contact forms, reach out to a local distributor, or contact their sales team for pricing information.

Source
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.

Landis+Gyr Gridstream: How do I request Landis+Gyr pricing?

Use the website contact form, reach out to a local distributor, log in as an existing customer, or contact Landis+Gyr sales directly for pricing details.

Source
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.

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.
