Emerson Ovation

  • 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 controlnot Azelio Energy Storage
  • A municipal water authority standardising treatment plant control across several sites under one NERC-adjacent security regimenot Azelio Energy Storage
  • An IPP wanting the DCS and the safety instrumented system engineered in the same tool rather than integrated across two vendorsnot Azelio Energy Storage
  • Hydro operators needing IEC 61850 and DNP3 into a control system that also runs the balance of plantnot Azelio Energy Storage

Where each one falls short

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

Azelio Energy Storage

Nothing recorded yet. See the Azelio Energy Storage review.

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.

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.

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.

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.
