The dispute was over a contract to install and commission a 220 KV power transmission network interconnecting the Democratic Republic of the Congo and Rwanda in Central Africa.
The stock rose 4.32 per cent to hit a high of Rs 414 on BSE.
Kalpataru declined to comment. An email sent by ET to Rwanda Energy seeking comment did not elicit any response till press time on Wednesday.
The Indian power transmission and distribution firm had entered a contract for the design, engineering, supply, construction, installation and commissioning of the network in November 2013. Construction began in October 2014 and the operational certificate was issued in May 2017.
In February 2016, Kalpataru raised a claim of about $24 million against Rwanda Energy for a price adjustment, as per the terms of the contract. However, Rwanda Energy informed the Mumbai-based company to raise the claim after the completion of the project. Soon after the completion of the project, when Kalpataru raised the claim in March 2017, it was disputed by Rwanda Energy.
As per the clauses in the agreement, the issue was referred to the Disputes Adjudication Board. In December 2019, the board ruled in favour of Kalpataru and said it was entitled to a price adjustment claim of $24 million-plus Rwandan franc of 35 million, along with interest of $3.6 million and Rwandan franc of 5.3 million.
Rwanda Energy challenged the ruling by initiating the arbitration process. A three-member arbitration tribunal, after hearing both parties, upheld the ruling.
