The Solar Titan 130 and Titan 250 comparison is about more than buying the larger turbine. Unit count, dependable output, service scope and the way a project uses electricity can change which arrangement makes sense.
Both are gas turbine products from Solar Turbines, not photovoltaic equipment. An electrical-power buyer also needs to distinguish a generating package from a mechanical-drive or compressor application before comparing specifications.
Use the Titan 130 and Titan 250 dossiers for model research. This guide adds a source-qualified rating comparison, unit-count examples and a method for evaluating the complete project.
Key Takeaways
- Use power-generation specifications when evaluating electrical supply.
- The current OEM pages list 16.53 MW for Titan 130 and 23.10 MW for Titan 250 at their stated ISO reference conditions.
- Reference ratings do not establish the output of a used package at its destination.
- Compare surviving capacity, scope and service obligations alongside unit price.
Start with the correct OEM reference#
The figures below come from Solar's current power-generation product pages, reviewed on September 18, 2026. They are reference specifications rather than site guarantees.
| Reference attribute | Titan 130 PG | Titan 250 PG |
|---|---|---|
| Published electrical output | 16,530 kWe | 23,100 kWe |
| Heat rate reported on the cited webpage | 9,630 Btu/kWh | 8,775 Btu/kWh; see source discrepancy below |
Sources: Solar Titan 130 power-generation page and Solar Titan 250 power-generation page. Retain each source's rating conditions and confirm the fuel-heating-value basis before using heat rates in an economic comparison.
Solar's linked February 2020 Titan 250 data sheet reports 8,670 Btu/kWh, while the webpage reports 8,775 Btu/kWh. The public sources do not establish which heat rate applies to a particular offered unit. These are attributed source observations, not a resolved performance specification or an apples-to-apples efficiency comparison.
Obtain the applicable OEM performance document before using either figure to compare fuel costs. Exhaust-temperature figures also differ between the sources and are omitted from this comparison.
Do not confuse shaft power with electrical output#
A mechanical-drive turbine performs a different job from a complete generating package. A horsepower rating or bare-engine description does not establish generator output, voltage, frequency or usable site power.
Request nameplates and an equipment list showing the generator, gearbox, controls and supporting systems. Then confirm that the offered configuration matches the intended electrical application.
Solar's Titan 130 generator-set data sheet and Titan 250 generator-set data sheet identify package components and electrical arrangements. Use those as reference documents, with the seller's as-built records establishing what is actually present.
Compare configurations at the required load#
The larger unit may reduce equipment count for one load target. A smaller unit may provide a more useful increment for another project's expansion or outage requirement. Test both propositions with site-specific ratings.
For an illustrative 40 MW delivered-load requirement, suppose engineering has established dependable net outputs of 14 MW for candidate A and 20 MW for candidate B. These values are hypothetical and are not Titan performance claims.
| Illustrative arrangement | Installed capacity | Capacity after losing one unit |
|---|---|---|
| Four units at 14 MW | 56 MW | 42 MW |
| Three units at 20 MW | 60 MW | 40 MW |
| Two units at 20 MW | 40 MW | 20 MW |
The first two pass this simple capacity screen; the second has no remaining capacity margin. The third meets normal demand but does not meet the same single-unit-outage requirement. Dynamic response, maintenance and common systems still require separate engineering assessment.
This calculation is more useful than comparing the catalogue MW of one turbine against another. Apply it at the initial operating phase and the final campus demand, using the actual part-load operating plan.
Choose unit size around the operating pattern#
An industrial site with steady electrical and useful thermal demand presents a different buying problem from a campus whose load arrives in several steps. The Titan comparison should begin with those differences. A higher individual output can reduce the number of packages for one requirement, while a smaller increment may align more closely with another site's expansion.
Create an operating table that records expected load, the number of units online and the capacity that must remain after the defined outage. Include low demand as well as the mature peak. If the selection only looks attractive at the final phase, identify the cost and operating constraints of reaching that phase.
Do not infer part-load performance from the ratio between load and rated MW. Request the appropriate curve. The offer should also state any operating limits relevant to the installed combustion system and required emissions performance. Those limits determine which dispatch cases are actually available, rather than merely possible in a spreadsheet.
For the illustrative 40 MW comparison above, consider the consequence of service work. Four 14 MW units and three 20 MW units each pass the stated single-unit-outage screen.
If one machine is already unavailable and another is lost, their surviving capacities become 28 MW and 20 MW, respectively. Neither meets 40 MW under that more demanding event definition. The appropriate response depends on the owner's requirements, not on declaring one turbine inherently reliable and the other unreliable.
Evaluate useful heat without confusing it with electricity#
EPA's explanation of combined heat and power describes production of electricity together with useful thermal energy. That distinction matters when comparing a power-generation package for an industrial facility with one serving an electricity-only load.
Ask what thermal service the project needs: its temperature or pressure, hourly demand and seasonal pattern. Then ask for a heat-recovery design that meets that service while accounting for the effects on the generating plant. A large exhaust heat resource has limited economic value if the facility cannot use it when the turbine is running.
Keep three quantities separate in the business case: electricity delivered, useful heat delivered and fuel consumed. Do not present a combined electricity-and-heat efficiency as the turbine's electrical efficiency. Also avoid assigning a fuel-saving credit to heat that is rejected or unavailable during the customer's demand period.
If useful heat replaces an existing boiler service, document the displaced fuel and the assumptions behind the comparison. If it supports cooling, define the additional thermal equipment and its performance. Either approach needs a project-specific assessment; a general CHP benefit should not become an automatic credit in a Titan purchase model.
Compare fuel economics only after resolving the specification#
EIA's heat-rate guidance establishes the fuel-energy-to-electricity relationship. Applying it to the Titans requires an applicable heat rate on a consistent energy basis and at the same electrical boundary. The conflicting Titan 250 references above are a reason to obtain that document, not a reason to choose the more favorable number.
For an invented comparison, assume Package A has a verified site-net heat rate of 10 MMBtu/MWh and Package B has 9.5 MMBtu/MWh on the same basis. At an assumed $5/MMBtu, their fuel costs are $50/MWh and $47.50/MWh. If each alternative supplies 200,000 MWh in the year, the annual fuel difference is $500,000. These assumptions do not describe Titan 130 or Titan 250 performance.
That result gives the buyer a way to evaluate a documented difference. It does not settle the purchase. Add service costs, installed scope, redundancy requirements and the value of any properly supported thermal service. If the operating hours change, recalculate the advantage instead of carrying the same annual saving into a different duty.
Evaluate the site around the package#
Ask for the general arrangement, maintenance clearances, removal path, lifting requirements and complete equipment footprint. The package enclosure is only one part of the plant layout. Fuel systems, exhaust, electrical equipment and access routes also occupy space.
Check gas conditions at the available supply point and at the turbine interface. Record any compression or treatment duty and its effect on net power. If a performance case includes inlet cooling, identify its equipment, water, electrical consumption and operating limits.
For heat recovery, define the useful thermal demand before assigning an economic credit. An exhaust stream does not create value merely because heat is available; the project needs a practical use and the equipment to deliver it.
Compare condition and service scope#
For each offered unit, obtain the maintenance timeline, inspection results, operating hours, starts and preservation history. Ask the service provider what work is required for the intended operating profile and what resources are available at the destination.
Treat replacement parts, controls support and warranty terms as items to document. The label “refurbished” should be accompanied by completed work and acceptance records. If work remains, separate its cost and schedule from the equipment purchase.
Use the used-turbine condition guide to structure the review. Normalize acquisition and installation scope with the used gas turbine cost guide.
Separate OEM pre-owned programmes from third-party offers#
Solar's pre-owned equipment programme describes an OEM-supported route for previously owned equipment. It should not be used to imply that every Titan on the secondary market receives the programme's inspection, service or warranty provisions.
Ask the seller to identify who performed any refurbishment and provide the completed work record. Obtain the actual warranty terms, including scope and exclusions, rather than attaching a programme description to an unrelated offer. When additional work is proposed, distinguish a quotation for that work from evidence that it has already occurred.
An asset advertised as “ready” also needs a release and preservation history. Establish whether it can be inspected in operation, is installed but shut down, or is stored. Each condition supports a different diligence plan. The buyer should know what can be demonstrated before payment and what remains dependent on installation at the destination.
Use a purchase decision sheet with explicit reasons#
For each Titan candidate, finish the evaluation with a decision sheet that can be understood without the sales brochure. Include the serial-number identity, delivered output requirement, applicable performance document, supplied scope and required work. List the unresolved items that could change cost or schedule.
The selection rationale should be specific: for example, “this configuration meets the defined operating phases with the required surviving capacity and a documented service plan.” Avoid a conclusion such as “larger is better” or “smaller is cheaper.” Neither explains how the equipment will serve the actual project.
Before committing, ask whether a different unit count or a different configuration would materially improve the plan. That is the point of the comparison: to identify a complete, supportable generating arrangement, with the appropriate Titan 130 or Titan 250 package as one component of it.
Frequently Asked Questions#
Is Titan 250 always the better choice because it has higher output?#
No. The decision depends on required net load, redundancy, operating phases, installed scope, condition and service commitments. Higher single-unit output is only one input.
Can a used Titan deliver the current webpage rating?#
That requires evidence for its configuration, condition and site. Obtain an applicable performance assessment rather than applying current catalogue values automatically.
Are 50 Hz and 60 Hz packages interchangeable?#
Do not assume they are. Identify the installed generator, gearbox, controls and electrical equipment. Any conversion requires a defined engineering scope; see the frequency compatibility guide.
Which Titan 250 heat rate should a buyer use?#
Use the applicable OEM performance document for the offered configuration and site. The webpage and linked older data sheet report different reference heat rates. This guide records the discrepancy without selecting either as the specification of a used unit.
Can recovered heat improve the project economics?#
Potentially, where a defined thermal load can use it and the required recovery equipment is included. Calculate useful heat delivered and the service it replaces. Keep that credit separate from electrical efficiency and avoid valuing heat the facility cannot actually use.
