Methodology
Prices: New OEM from Gas Turbine World Handbook 2025 (○ inferred). Grey market from broker listings Q1 2025 (○ inferred — wide range is intentional; condition and counter-history dependent).
SCR adder: Per-unit EPC benchmarks (○ inferred). Non-attainment only. Catalyst lead time 4–6 months additional — not in lead time shown.
What is excluded: Civil works, gas interconnect, switchgear, black-start, site works, EPC, commissioning, contingency. Full installed power-island cost is typically 2–3× the equipment estimate shown.
Market condition premium: 10% OEM uplift applied in constrained mode (OEM capacity statements 2025–26).
Adjust inputs to compare all units.
Known limitations
Equipment prices are screening estimates, not quoted procurement terms. Grey-market pricing is condition- and counterparty-dependent. SCR requirements depend on site-specific permitting, runtime, emissions profile, and source aggregation. Project MW reflects announced capacity and may differ from commissioned capacity. Lead times are OEM-stated ranges and may extend under demand pressure. Jefferies Research (Jun 2026): approximately 60% of the total data centre pipeline and ~70% of planned 2027–2028 capacity is at risk of schedule slippage due to permitting friction and infrastructure constraints — budget for delay in interconnection and BTM infrastructure, not just equipment. Global gas turbine orders 110 GW at end-2025 vs manufacturing capacity 60–70 GW; structural bottleneck is hot-section single-crystal turbine blade production (handful of foundries globally) — orders placed today deliver no earlier than 2029 (EPRI Jun 2026). GEV Q2 2026: >50% of 2031 production already sold — demand has been pulled forward further than any prior cycle. INNIO Q2 2026: equipment backlog $6.6B provides visibility 'at least into 2030.' Execution risk is now the primary risk, not demand: INNIO shares fell 13.6% on the earnings release (Jul 28 2026) and stayed under pressure through August (~-36% peak-to-trough over 30 days) despite record orders — market separating order intake from margin delivery. Market-widening signal: Doosan Enerbility (South Korea) broke into US DC gas turbine market with 12 units under contract (xAI Colossus 5 × 380 MW + 7 units unnamed DC, delivery 2026–2029) — when incumbents are supply-constrained, competitive field widens. Mobile/hypermobile power emerging as distinct sub-category: Baker Hughes / Dynamis DT17 platform (76 × NovaLT16, ~1.3 GW, Jul 29 2026) purpose-built for rapid deployment DC and O&G applications where permanent infrastructure is unavailable. Engine delivery timeline (Evercore ISI analyst David Raso, Jun 2026): new large recip engine orders landing in late 2027 at earliest, most slotting into 2028 — engine supply now as constrained as large-frame turbines. Siemens Energy Q3 FY2026 (Aug 5 2026): backlog €162B (+20% YoY); Gas Services book-to-bill 2.65 — demand running at 2.65× production capacity. Large turbine lead time ~5 years; small turbine 18–36 months. 70% of 2025 unit orders were sub-100 MW. New gas turbine pricing tracking 10–20 pts higher $/kW in H1 2026 vs Q4 2025 (GE Vernova Q1 earnings Apr 2026).
Outputs are equipment-level screening estimates, not installed EPC estimates. Use for option screening only — not final financing or EPC cost models. Full installed power-island cost is typically 2–3× equipment estimate. OEM pricing from Gas Turbine World Handbook 2025 (FOB factory). SCR cost from EPC benchmarks — vary by site, catalyst type and throughput. Grey market pricing from broker ranges — condition and counter-history dependent.

v2.2 Sep 12 2026 Update
A third order book, a pipeline that grew 50 per cent in six months, and the first dated per-kW equipment prices this tracker has carried.
  • Mitsubishi Power is added at 35 GW of large-frame backlog, up from 23 GW a year earlier. This tracker ranked two order books when there are three. On the firm basis the ranking is Siemens 69, GE Vernova 53, Mitsubishi 35 — and on GE Vernova’s headline 116 it inverts, which is why the firm basis is the one to use.
  • Global Energy Monitor puts 378 GW of US gas in development, up from 252 GW in January, with 189 GW tied to data centres. The line that matters for a modular tracker: reciprocating engines in development reached 67 GW, of which 45 GW is data-centre-linked — a tripling in six months. Carried as a third cross-check with its own perimeter, not merged with the other two.
  • First dated per-kW prints: HD Hyundai supplied 1 GW of 9.6 MW HiMSEN engines for US$675.6m, about US$676/kW equipment-only, against US$620/kW in April. Both sit at the top of this tracker’s US$350–700 band and both test it rather than widen it.
  • Caterpillar is restarting the 10 MW medium-speed gas reciprocating platform halted in 2022, returning 1.5 GW of capacity with shipments from Q4 2026. Power generation retail sales ran +72 per cent year on year.
  • Fleet Data Centers’ 360 MW in Nevada is added as the clearest bridge-power instance yet: two methane plants stated to run “between two and three years, until NV Energy can deliver permanent utility service”. Bridge power with a stated handback date is a different economic animal from permanent behind-the-meter, and this tracker had no instance of it.
  • Pennsylvania’s 19 August executive order conditions expedited permitting for data centres above 25 MW on bringing new generation within the project’s own PJM zone, with firm clean power at 10 per cent by 2027 rising to 32 per cent by 2035.
Two basis traps, one of which caught a researcher this month
Caterpillar’s US$72bn is an enterprise-wide order backlog disclosed on an earnings call, not a Power Generation segment figure — and Caterpillar’s own Q2 release discloses no backlog at all. At least one outlet reported it as a power generation number in September. Separately: Siemens Energy is not Siemens AG. Siemens AG’s Q3 2026 release reports a record group backlog of €132bn for the industrials parent and carries no gas turbine figure. A researcher reading that release as a Siemens Energy disclosure this month concluded this tracker’s €162bn was wrong. It is not — the figures belong to different companies.
Caterpillar Q2 2026 release and call; Siemens AG Q3 2026 release; Siemens Energy Q3 FY2026
The pipeline grew; the conversion rate did not
A 50 per cent rise in announced development capacity is a demand signal, not a supply one. This tracker’s wider cross-check still shows roughly 2 GW operating against 90 GW announced — a 2.2 per cent conversion — and nothing in the new data moves that ratio. Accelleron, which sits upstream of several engine OEMs and is the best independent proxy for prime-power volumes, more than doubled deliveries to 5 GW in the half while noting that some data centre customers are delaying orders.
Global Energy Monitor, Aug 2026; Accelleron H1 2026, 27 Aug 2026
v2.1 Sep 07 2026 NewUpdate
A wider net finds four times the announced capacity and almost none of it running. Announced and delivered behind-the-meter capacity differ by a factor of forty-five.
  • Cleanview tracks 59 behind-the-meter data centre projects at about 90 GW announced, against this tracker’s 21 at 20.5 GW — a wider definition including early-stage announcements and non-gas. Carried as a cross-check, not merged.
  • The number that matters is the same in both. Roughly 2 GW is actually operating, about 2.2 per cent of the announced book, with a further 1.2 per cent under construction, 36 per cent permitted and 60 per cent merely announced.
  • Amazon’s GW Ranch in Pecos County, Texas is added: 7.65 GW of permitted gas across 35 turbines on 8,000 acres, plus 1.8 GW of storage and 750 MW of solar, initially off-grid. Amazon’s ownership was only disclosed in August 2026, through permit records. The 7.65 GW is gross generation; no IT load has been disclosed.
  • Chevron’s Project Kilby is added at 2.67 GW gross, with Microsoft as offtaker on a 20-year agreement, GE Vernova large-frame turbines plus Solar Turbines, first power 2028. Kilby is in Reeves County and GW Ranch is in Pecos County — the town of Pecos sits in Reeves, and the two are easy to conflate.
  • Circe Energy is added as a genuinely new entrant: West Texas AI Campus in Midland County, 150 MW by 2027 rising to 1,100 MW by 2030, with about 2 GW of Cummins reciprocating generation ordered for 2026 to 2030 delivery.
  • No outright cancellation of any named project was found in the window. Every adverse item is a delay. The claim that half of 2026 US capacity would be cancelled traces to one estimate that about 5 GW of an expected 12 GW was under construction; SemiAnalysis disputes the denominator and reports its own forecasts moved 1 to 5 per cent. Both stand and neither is settled.
  • None of the four largest projects in the scan discloses a critical IT load. Every headline figure is gross generation or unstated, so none of them converts.
Announced capacity is not a pipeline
Two gigawatts operating against ninety announced is a 2.2 per cent conversion rate. Any model that treats announced behind-the-meter capacity as deliverable supply is out by more than an order of magnitude.
Cleanview behind-the-meter tracker, mid-2026
v2.0 Sep 07 2026 Fix Structure Update
The two OEM order books were being compared on different bases, and the Siemens Energy figure had no source. On firm orders the ranking reverses.
  • GE Vernova’s 116 GW is 53 GW of firm equipment backlog plus 63 GW of slot reservation agreements. A slot reservation is a paid option on a manufacturing slot, not a contract to buy a machine. The block now carries the split and every page that quoted the headline quotes the basis with it.
  • Siemens Energy moves from 87 GW to 69 GW. This is not a quarter-on-quarter change: the 87 GW had no locatable primary source, and 69 GW is the reported figure at 30 June 2026. Siemens Energy does not publish a gigawatt backlog in its earnings release at all — it discloses a EUR 162bn total order backlog and a book-to-bill of 1.57 and stops there — so the new number is reported, not filed, and is flagged as secondary.
  • The consequence is the headline finding. Comparing 116 to 69 says GE Vernova’s book is 68 per cent larger. Comparing firm to firm says Siemens Energy’s is 30 per cent larger. The ranking reverses on the basis, and three pages had it the wrong way round.
  • OEM output is separated from modular output. GE Vernova runs about 20 GW a year of total annualised gas turbine capacity rising to 30 GW by 2030, and Siemens Energy 15 to 16 GW with its announced expansions. The 4.7 GW figure this tracker carries is the modular subset available to US data centre behind-the-meter, and the two were being read interchangeably.
  • Lead times and slot availability added: Siemens Energy states more than three years, GE Vernova about three on new heavy-duty. GE Vernova entered Q1 2026 with roughly 10 GW of 2029 slots and left it with about 10 GW across 2029 and 2030 combined.
  • Equipment pricing trend added: 10 to 20 points higher per kW in Q1 2026 than Q4 2025, with GE Vernova projecting US$600/kW by end-2027, which sits inside the US$350–700/kW band this tracker already carried.
Firm orders and slot reservations are not the same commitment
GE Vernova publishes both inside one headline; Siemens Energy publishes no equivalent line. Any ranking of the two books has to be struck on firm orders, and EE_SYNC.gas.oemBacklogGW.comparableBasis now names which field to use.
GE Vernova Q2 2026, reported 22 Jul 2026 · Siemens Energy Q3 FY2026, reported 10 Aug 2026
Siemens Energy 87 GW was unsourced
Changing it is a move from an unsourced number to a sourced one rather than from one disclosure to another, and the confidence flag says so on the face of the block.
Siemens Energy Q3 FY2026 earnings release · Utility Dive, 10 Aug 2026
v1.9.1 Aug 18 2026 Fix Structure
Caterpillar now ranks on observed delivery of about 46 months rather than its 6 to 12 month quote.
  • Caterpillar's G3516 and G3520 carry two lead times: the 6 to 12 month manufacturer quote, and the roughly 46 months actually being achieved at current order volumes. The speed ranking now sorts on the delivered figure, which reverses where Caterpillar sits as a fast bridge option.
  • Cummins 4 MW moved from 6 to 12 months to 24 to 36 months. The natural gas prime power unit is not yet in production and Cummins guides to 2028 delivery.
  • The pipeline is now split by commitment state: 14.9 GW firm across operational, ordered and permitted units, against 5.6 GW of framework agreements, for 20.5 GW across 21 projects. All of it counted on equipment capacity rather than announced campus size.
  • That 14.9 GW firm order book is 1.9 times the entire on-site generation fleet the 2040 forecast expects by 2030.
  • INNIO's J624 price is flagged as unresolved. US$420 to 560 per kW is the floor, and the VoltaGrid financing implies US$870 to 978 per kW, roughly twice apart. Both are shown rather than averaged.
Fix
Cummins 4 MW lead time — the Pricing Model and the Price Reference disagreed by 24 months. MODEL_DATA.cummins4mw carried 6–12 months and ranked Cummins as a fast bridge option, while PR_DATA.cummins4mw carried 24–36 months with the caveat “product not yet in production, 2028 delivery.” Set to 24–36 months to match the sourced caveat, with a note on the pricing row: the NG prime-power config is not yet in production and 2028 is Cummins’ own guidance (2026 Analyst Day, Jun 2026).
Cummins 2026 Analyst Day (Jenny Bush, Power Systems) · Jun 2026
Fix
Caterpillar G3516 / G3520 — OEM quote and market reality now carried side by side. Both arrays said 6–12 months while the caveat text cited RBC Capital Markets (Jun 2026) reporting actual Cat recip delivery at >200 weeks (~4 years). Judged the 6–12 to be the OEM quote and >200 weeks the delivery actually being achieved, so both are carried explicitly: leadLoMonths/leadHiMonths = 6/12 (OEM quote) plus a new leadActualLoMonths = 46 surfaced in the pricing table as a second, red line labelled “actual”. The procurement ranking (fastest delivery, best bridge fit) now sorts on the actual figure, not the quote — previously Cat ranked as a 6-month bridge option on a unit with a four-year queue.
RBC Capital Markets Global Energy Conference · Jun 3 2026
Fix
The lead-time correction reached two of three views — Equipment tab now completed. The two fixes above updated MODEL_DATA and PR_DATA but left the EQ array untouched, so the Equipment tab detail cards still showed 6–12 mo for all three units. EQ.cummins4mw 6–12 mo → 24–36 mo, matching MODEL_DATA and the Price Reference 2028-delivery caveat. EQ.cat3516 and EQ.cat3520 6–12 mo → 6–12 mo (OEM quote) plus a second red line, >200 wk (~46 mo) actual, carrying both figures the way MODEL_DATA does — the OEM quote is not overwritten, because the ~34-month divergence between quote and delivery is the point. A sourced lead-time basis note now renders on each affected card, and the RBC Capital Markets attribution was added to both Caterpillar source lists. All three views now agree.

Project KPIs now derive from PROJ by status, not by category. The strip reported cat-based totals (site MW / framework MW), which is a display taxonomy, not a commitment state. It now computes at runtime: firm = Operational + Ordered + Permitted = 14,925 MW (14.9 GW), framework = Framework + Framework signed + Testing (Q3 2026) = 5,550 MW (5.6 GW), total 20,475 MW (20.5 GW) across 21 projects — matching EE_SYNC.gas.pipelineGW exactly, which is what the Forecast 2040 and RV models now cite. Both sums are on equipment MW (mwAero + mwRice + mwGrey + mwUnknown) rather than announced campus MW: the Joule Utah row is a 4,000 MW campus with 1,500 MW of gensets ordered, and counting the campus headline would have inflated firm to 17,425 MW. A one-line definition of firm vs framework sits under the strip.

Update
INNIO Jenbacher J624 flagged critical — the published range contradicts its own derivation. The row computes $870–978/kW equipment-only from the VoltaGrid Oct 2025 financing ($5B ÷ 2,300 MW = $2,174/kW all-in, equipment at 40–45%) but publishes $420–560/kW on GTW comparables — roughly 2× apart — and was marked critical: false. Set to critical: true so downstream consumers of oem_lo/oem_hi see the flag, and the discrepancy is now printed in the price cell itself rather than being buried in the collapsed method prose. Read $420–560/kW as a floor and $870–978/kW as the financing-implied ceiling; the tracker does not resolve them.
