The new FX-45 gives you a repeatable gas turbine block to firm each phase of solar and storage.
A Repeatable Thermal Brick
We think hybrid portfolios need a standard thermal building block. USP&E positions the new FX-45 as that block for developers firming renewables at scale. USP&E is a full-service EPC and O&M contractor, not a broker.
Why Repeatable Firming Blocks Help
Each phase of a renewable portfolio brings variable output that must be firmed. Using the same thermal block every time means the same foundations, the same control interface, the same spares and the same operating procedures. Engineering effort falls with every phase, and operators learn one machine well.
The New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA is designed as such a block, available for 50 Hz and 60 Hz systems with slots from 2028 to 2030.
How FX-45 Blocks Work With Solar and Storage
In a hybrid plant, solar provides energy when available and storage shifts and smooths it. FX-45 blocks provide firm capacity when both fall short, and can support grid stability needs such as frequency response and reactive power where the design calls for it.
The hybrid controller decides when to start blocks, keeping turbine running hours to what reliability requires. Our sister team covers broader gas turbines for renewable firming.
Planning Your Portfolio
USP&E models each phase’s load, renewable output and storage, then sets how many FX-45 blocks are needed and when. Slots are reserved to match the portfolio timeline, with used turbines available as earlier bridge capacity.
Solar-led phases can draw on our sister team for solar EPC delivery.
USP&E Offices for Hybrid Firming
Colorado Springs (1755 Telstar Dr, Suite 300) is where many FX-45 firming blocks requests are scoped; Knoxville (800 S Gay St, Suite 700) follows them into procurement and field execution. Portfolio firming studies are usually led from Colorado Springs, with London supporting financing models. Cape Town (31 Brickfield Road, Woodstock) and Johannesburg (22 Kildoon Rd, Bryanston) contribute site teams that have worked in heat and dust, London (162-168 Regent Street) handles finance-facing work, and Wuxi (No. 1, Ningzhou Road, Wuxi) keeps manufactured components moving. Regions: USA | AFRICA | UK | UAE | CHINA. The record is 150+ power projects in 45+ countries and 25,000 MW contracted since 2002, run. ISO 9001 and ISO 45001 certified.
Turbine Delivery Record
You are planning firming capacity for years ahead. Here is the turbine work behind our offer.
- USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers.
- NEOM, Saudi Arabia: USP&E supplied three zero-hour Siemens SGT-400 gas turbines. Read the case study.
- Resolute Mining, Syama, Mali: USP&E installed and operated a 30 MW Caterpillar power station from 2007 to 2010. Read the case study.

FAQ: FX-45 firming blocks for renewable hybrids
What is an FX-45 firming block?
USP&E uses the term for a new FX-45 gas turbine unit used to provide firm capacity behind solar and storage. Each 45MW block is the same, so every portfolio phase can reuse the same design and procedures.
Why use repeatable firming blocks?
USP&E recommends repeatable blocks because they reduce engineering effort, simplify spares and training, and make each phase faster to deliver than designing a new thermal solution every time.
When are FX-45 slots available?
USP&E offers capacity slots for the New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA from 2028 to 2030, for 50 Hz and 60 Hz systems.
Can FX-45 blocks support grid stability?
USP&E designs hybrid plants so turbine blocks can support frequency response and reactive power where grid codes require it, coordinated by the hybrid controller.
What if I need firming before 2028?
USP&E can supply used gas turbines or remanufactured GE Frame 6B units from inventory as bridge firming, integrated so FX-45 blocks can join later.
Is USP&E a broker?
No. USP&E is a full-service EPC and O&M contractor, not a broker. We plan, build and operate hybrid plants including their firming blocks.
Which offices support firming studies?
USP&E supports firming studies from Colorado Springs and Knoxville in the USA, London for finance, Johannesburg and Cape Town for African portfolios, and Wuxi for supply chain.
Are FX-45 performance figures published?
USP&E shares project-specific technical information with qualified buyers during scoping. Public information covers the 45MW block, 50 Hz and 60 Hz options and 2028 to 2030 slots.
Take the Next Step With USP&E
The good outcome is simple: FX-45 firming blocks with one accountable team and no surprises at commissioning. The bad one is a half-finished package nobody owns. Contact USP&E, phone +27 10 822 2324 or email info@uspeglobal.com, or search inventory now.
