Diamond Power Share Price Hits 5% Upper Circuit; Receives ₹179.43 Crore Order from Adani Electricity Mumbai

Diamond Power Infrastructure Limited has received a Letter of Award from Adani Electricity Mumbai Limited (AEML) for supplying specialised power cables for Mumbai's distribution network, as per the exchange filing. The order is valued at ₹179.43 crore, including GST, and covers around 871 km of cables. 

The award includes both medium-voltage and low-voltage underground cables. For Diamond Power, it also continues a relationship with AEML that has now entered its third consecutive year.   

Order Covers 871 Km of Underground Cables 

The order includes 33 kV and 11 kV medium-voltage cables along with associated 1.1 kV low-voltage cables. The quoted price includes packing and forwarding, freight, and transit insurance. The formal purchase order will follow the Letter of Award.  

Deliveries are scheduled to start after manufacturing clearance, with a planned rate of about 50 km per month. This rate can be increased depending on project requirements.  

Cables Designed for Mumbai Conditions 

The cables are built with TR-XLPE insulation, water-blocked conductors, water-swellable tapes, and an HDPE outer sheath. The construction is intended to protect the cables from moisture-related problems in Mumbai's coastal and heavy-monsoon environment.  

The company said the specialised design addresses water treeing, where prolonged exposure to moisture and electrical stress can gradually weaken cable insulation. The water-blocking construction is designed to restrict moisture movement if the cable's outer protection is damaged.  

Third Consecutive AEML Award 

This is the third consecutive year in which Diamond Power has received this contract from AEML.  

The company said the repeat award reflects AEML's assessment of its CCV manufacturing capability, in-house testing facilities and delivery record on the Mumbai network. Diamond Power also supplies cables to BEST.  

The company manufactures these cables using CCV lines, triple-extrusion technology and controlled processing, supported by in-house testing facilities.
