Siemens transformer protection relays for Potia Substation, Chattogram
Client sector: Electrical transmission substation
Location: Potia, Chattogram, Bangladesh
Year: 2017
Product: Siemens SIPROTEC transformer‑protection relays (types 7SJ6225‑4EB00‑1FC1 and 7UT6125‑4EB00‑1BA0)
Procurement channel: Direct import under Impro Solutions Bangladesh / Impro Solutions UK Ltd
Project context and challenges
The Potia substation project required transformer‑protection relays urgently. The utility issued a request for quotation with a very tight delivery schedule and insisted that the goods come from Siemens’ German factory. At the time there was no local stock, so our sourcing team needed to find a reliable supply within days. Delays would have left the substation without protection equipment and risked grid instability.
Our approach
- Rapid sourcing: Within hours of receiving the RFQ we contacted Siemens’ German sales office and confirmed availability of the 7SJ6225 and 7UT6125 relay models. Because these devices are made‑to‑order, we arranged to purchase units that were already in the production queue.
- On‑site inspection: To ensure quality and compliance we travelled to Germany, inspected the relays at the factory and witnessed factory acceptance tests. Photos from our visit show the front panel of the SIPROTEC relays with their menu controls and indicator LEDs and the rear of the units with labels and connection terminals.
- Customs and logistics: We handled all export documentation and coordinated with freight forwarders to ship the equipment by air. Our understanding of Bangladesh import regulations allowed us to clear customs quickly and avoid demurrage.
Outcome
The relays arrived at the Potia substation ahead of schedule. The client confirmed that the units were genuine Siemens products and matched the specified types. By managing the entire procurement process—from sourcing to on‑site inspection and customs clearance—we met the client’s urgent timeline and prevented costly project delays.
Lessons learned
- Early engagement with the manufacturer can reveal stock or near‑finished units that shorten lead times.
- On‑site inspection builds trust and ensures that products meet specifications.
- Knowledge of local import procedures is critical for fast delivery on projects where timing is vital.

EDMI energy meters for Meghnaghat EDRA BD CCPP
Client sector: Combined‑cycle power plant
Location: Meghnaghat, near Dhaka, Bangladesh
Year: 2017
Product: EDMI Mk6E advanced energy meters and accessories
Procurement channel: Competitive tender, imported through Impro Solutions Bangladesh
Project context and challenges
The Meghnaghat CCPP required replacement of its revenue‑metering equipment. The tender called for EDMI Mk6E three‑phase energy meters with communication modules and software. Competition was intense; bids were evaluated strictly on price, delivery time and compliance. Winning the tender required careful cost control without compromising quality or service.
Our approach
- Competitive pricing: We analysed the tender documents and optimised our supply chain to be the lowest qualified bidder. By sourcing the meters directly from EDMI’s regional distributor in Singapore and consolidating shipments, we reduced freight and handling costs.
- Comprehensive supply: The order included Mk6E meters, RS232/RS485 communication cables, EziView meter‑reading software and optical read heads. Each meter was supplied with a calibration certificate and battery installation date.
- Post‑delivery training: After delivery to the plant we organised a technical meeting in Singapore for the client’s engineers. This hands‑on session covered meter configuration, integration with the plant’s SCADA system and long‑term maintenance. Our team also provided remote support during commissioning.
Outcome
We delivered the complete meter package on time and at the lowest compliant price, winning the tender. The plant’s metering system now provides accurate revenue and power‑quality data, helping the operator meet regulatory requirements. The client appreciated the extra training and support, which ensured that the meters were correctly commissioned and fully utilised.
Lessons learned
- Careful cost analysis and supply‑chain optimisation can make a bid competitive without sacrificing quality.
- Providing training and after‑sales support builds long‑term relationships with power‑plant clients.
- Documentation such as calibration certificates and battery installation dates give clients confidence in product authenticity.
