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.; Helioscope licences are single user, so each designer needs their own
  • They diverge on capability: Emerson Ovation covers Power application libraries, Helioscope covers PV system design.
  • 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.

Helioscope

  • Licences are single user, so each designer needs their own
  • Projects are capped at 10 a month on both Basic and Pro
  • System size is capped by plan, at 1.25 MW DC on Basic and 5 MW on Pro, so a larger array forces an upgrade regardless of project count
  • Trackers, LIDAR modelling and API access sit on the higher tiers
  • Enterprise is priced per project with no published figure

Questions people ask

Is Emerson Ovation or Helioscope better?
Neither clearly leads. Emerson Ovation starts at On request and Helioscope at $159/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Emerson Ovation or Helioscope?
Emerson Ovation starts at On request and Helioscope at $159/month.
Does Emerson Ovation or Helioscope run on more platforms?
Emerson Ovation runs on Windows, On-premise. Helioscope 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 Helioscope is typically brought in for.
What can Emerson Ovation do that Helioscope cannot?
Emerson Ovation covers Power application libraries, Ovation SIS, Embedded historian, NERC CIP tooling. Helioscope covers PV system design, 3D shade modeling, Performance simulation, Single-line diagrams.

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.

Helioscope: What is the starting price for HelioScope?

HelioScope Basic plan costs $159 per month per license with annual billing at $1,620/year (15% discount). The Pro plan is $259/month or $2,640/year. Each license covers 1 user. Source: https://helioscope.aurorasolar.com/pricing

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.

Helioscope: How many projects can I design monthly with HelioScope Basic and Pro?

Both Basic and Pro plans include 10 projects per month, equaling 120 projects per year. The project allocation is the same across both tiers; the difference is in design capability (1.25 MW for Basic vs. 5 MW for Pro). Source: https://helioscope.aurorasolar.com/pricing

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.

Helioscope: What is the maximum solar design capacity by HelioScope tier?

HelioScope Basic supports designs up to 1.25 MW DC, Pro supports up to 5 MW DC, and Enterprise supports unlimited designs up to 30 MW DC. Accuracy within 1% of PVsyst modeling is maintained across tiers. Source: https://helioscope.aurorasolar.com/pricing

Source
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.
