The Supreme Court on Wednesday upheld the Maharashtra Electricity Regulatory Commission's (MERC's) approval of the purchase agreement that allows Tata Power to allot 800 MW to Brihanmumbai Electric Supply and Transport (BEST) and 500 MW to Reliance Energy.

With this judgment, the apex court has set aside the Appellate Tribunal for Electricity's ruling that directed MERC to consider Reliance Energy's claim over power generated by Tata Power.
