Application For Block Listing

 

London, UK - Mast Energy Developments PLC (LSE: MAST) is pleased to announce, further to its RNS announcement dated 20 August 2025, significant progress on its 7.5 MW Hindlip flexible generation power project, which is fully funded in partnership with Powertree, the highlights and details of which are outlined below.

 

Key Highlights:

· Engineering, Construction, and Procurement ("EPC") progress at Hindlip 7.5 MW flexible generation power project takes significant step forward with arrival of the Rolls-Royce mtu low-carbon reciprocating gas turbine engines, which is typically the longest order lead-time capex item and the critical path to commercial operations date ("COD");

· Rolls-Royce mtu 20V4000 GS low-carbon reciprocating gas turbine engines secured through Yellow Power, a leading UK EPC company focused on Rolls-Royce mtu power solutions;

· See photos below of Hindlip's engines being assembled;

· The Rolls-Royce mtu 20V4000 series offers world-class efficiency, reliability, and lower emissions, making it one of the most competitive engines for decentralised flexible power generation;

· Stamford HV804X alternators paired with the engines deliver clean, stable output with industry leading >96% efficiency and low harmonic distortion, supporting electricity grid resilience; and

· Site full construction works (including inter alia civils, LV and HV electricals, and grid- and gas connection) progressing, keeping the project on track to complete construction and reach COD in Q2 2026.

 

Technical Prowess of the Rolls-Royce mtu 20V4000 GS Engines:

· 20-cylinder V-configuration, lean-burn low-carbon reciprocating natural gas turbine engine with turbocharging;

· World class electrical efficiency ~42% with high total efficiency when combined with heat recovery options;

· Robust design proven across global power applications, with low maintenance overheads;

· Engines are certified for hydrogen and green-gas readiness, ensuring long-term sustainability and use of engines; and

· Excellent local operations and maintenance support via Yellow Power and Rolls-Royce.
