Reliance Power had reported results for the December quarter showing a marginal growth in net profits - and the growth was driven by a fall in expenses rather than a rise in total revenues. The company features in the Benjamin Graham Value Screener, with a Graham ratio greater than 1. 

Graham ratio is calculated as (Graham Number/Stock's Share Price). A ratio greater than 1 means that the Graham number is higher than the stock price, meaning that the stock is selling at a good price. Reliance Power has a Graham number of 1.8. 

While this is the case, Reliance Power is facing some mining regulation challenges. The company's Madhya Pradesh plant is facing shutdown due to the coal mining cap placed by the government. The cap of 17 million tonnes per annum of coal, leaves it without enough for its power project. The court is awaiting the government's response, and the issue is not yet resolved.
