Sourced engineering details
The combined-cycle gas block at Pulrose only. Adjacent diesel equipment and wider-site totals are excluded.
Installed or rated capacity (MW), generator apparent power (MVA) and annual electricity generation (MWh/GWh) describe different quantities. None is live output. No live telemetry is connected to this profile.
- Generator / unit ratings
- Gas alternators: 2 × 41.25 MVA; steam alternator: 31.625 MVAReported source record
Source period: Historical Manx Electricity Authority technical brochure; publication date not stated
The brochure identifies ABB AMS-1250-LK gas alternators and an LDW S5E11 20 M66-42P steam alternator. It lists two 32 MW gas-turbine outputs, 23 MW steam-turbine generator electrical output, 87 MW gross, 3 MW auxiliary demand and 84 MW net. The operator overview separately reports 88 MW for the block; the difference is not reconciled by the checked sources. MVA is apparent power, not MW or present output.
- Grid connection voltage
- 33 kV switchhouse reported; precise connection point not confirmedReported source record
Source period: Historical technical brochure; publication date not stated
This is the published switchhouse voltage. It must not be relabelled as generator-terminal voltage or a verified current point-of-connection specification.
- Turbine type
- 2 × GE LM2500+ aero-derivative gas turbines + 1 × MAN steam turbineReported source record
Source period: Historical technical brochure; operator overview describes the block built in 2003
The brochure identifies the steam turbine as MAN DK080/250RZ1. Equipment descriptions concern the documented configuration; no claim is made about current availability, overhaul status or uprating.
- Annual electricity generation
- 417 GWh in the year ended 31 March 2025Reported source record
Source period: Financial year 2024/25; annual report published as Tynwald GD 2026/0048
The operator reports 417 million kWh specifically from Pulrose's combined-cycle plant. The report does not identify the gross/net metering boundary in that paragraph. Diesel generation is reported separately and is not added here.
- Operating principle
- Gas turbines generate electricity; exhaust heat raises steam for a second generating cycleReported source record
Source period: Historical technical brochure; publication date not stated
Heat-recovery steam generators recover gas-turbine exhaust heat for the steam turbine. The two diagram paths show energy conversions, not alternators electrically connected in series or an operating procedure.
Illustrative energy paths
Gas-turbine electricity path
- Air + natural gas
- Gas turbines
- Gas alternators
- Electrical network
Recovered-heat electricity path
- Gas-turbine exhaust heat
- Heat recovery → steam
- Steam turbine + alternator
- Electrical network
The paths show the combined-cycle principle, not site piping, busbars, switchgear or a single-line diagram. Diesel generation is omitted from this CCGT illustration.

The gas block and the wider site
Manx Utilities describes an 88 MW combined-cycle gas-turbine block built in 2003. The adjacent diesel station is a separate installation sharing the site and control room. This atlas record covers the CCGT block only, so its 88 MW must not be compared directly with the operator's nearly 135 MW figure for the wider Pulrose site. Manx Utilities: power stations.
Technology and record limits
The operator describes aero-derivative gas turbines and a 7 July 2003 opening. Combined-cycle technology couples a gas-turbine cycle with heat recovery and a steam cycle. Owner identity is not separately reported in this inventory; the operator field must not be silently substituted for ownership. Manx Utilities: Pulrose CCGT.
Location and interpretation limits
NESO grid reference SC 367 756 has 100-metre precision. This record describes the 88 MW CCGT block; adjacent diesel units are excluded. Supported by National Energy SO Open Data.
A representative coordinate is not a surveyed boundary or a grid connection diagram. Rated MW is not real-time output. Historical annual generation is separately dated; this profile does not verify current dispatch or availability.
