32. Having regard to the submissions of both the parties and relevant regulations of the CERC, we are of the view that as per the prudent industrial practice, the installation of CCTV for surveillance and safety of vital installations is essential. As in the instant case, it has also been recommended by Government instrumentalities to install adequate numbers of CCTV for surveillance of the plant and ensuring safety measures for fire etc. in the cable galleries. Thus, the estimated projection for installation of requisite number of CCTVs by the Appellant requires consideration by the CERC without insisting much on the procedural information whatsoever. In fact, the Commission has to accord in-principle approval only for the proposal of the Appellant in this regard, and the actual amount would need to be allowed after prudence check in the true up exercise. As CERC has allowed similar expenditures in other thermal power plants of the Appellant, there does not appear any visible reason for not allowing the same in the instant case. This is also required for CERC to take a consistent view in all the cases rather than adopting selective approach from case to case on same plea. We are therefore, of the considered view that CERC has passed the impugned order in an inconsistent way without adequate evaluation of the case in hand.”
