India's state electricity board switches to FOSS and saves 8 million

Kerala State Electricity Board (KSEB) switched to open source solutions only a few years back, and now, not only manages the accounting and billing information of users across Kerala, but has made impressive savings, year-on-year, using FOSS.
The KSEB was introduced to open source with the billing software Oruma in 2006, and it has not looked back ever since. Its implementation was soon followed by Saras, an accounting software used in expenditure accounting. As a result, KSEB has managed to save Rs 7-8 crore.
