Functions of Energy Accounting:-

 Deviation Settlement Mechanism  Monthly InSTS Loss computation  RECs in Maharashtra  Open Access  Other Miscellaneous Work

23

 MERC issued another order for implementation of Intra-State ABT in Maharashtra in Case 42 of 2006 dated 17 May 2007.

• Rates of settlement are not linked to frequency.
• Rates of settlement are as per Weighted Average System

Marginal Price (WASMP).  MSLDC implemented FBSM from 1st Aug 2011 with state

• MOD. (4 Discoms and 6 Merchant generator). At present,

there are 9 Discoms and 9 generators  Maharashtra is the first state to implement 15 mins Intra- State ABT in India.

Deviation Settlement Mechanism

Metering inputs for FBSM Billing

 The calculation of State Grid Transmission (InSTS) Losses is as

per the methodology prescribed by the MERC in its order in Case No. 31 of year 2006.

 InSTS Losses were calculated as per data received from

MSETCL, TATA, R-Infra, BEST, MSPGCL and WRPC by conventional method i.e. manually prepared vide excel sheets.

 MSETCL had developed Energy Accounting System module

from ERP software and from 1st November 2016, InSTS loss has been computed in ERP-EAS system.

RECs in Maharashtra

• Maharashtra has the largest number of registered

generators for REC.

• At present total number of 375 generators with 990

MW capacity are registered under REC in the state as

• n March-2018.
• MSLDC has been issuing EIRs for REC generators since

2010 well within time frames.

Renewable Energy Certificate - software

Open Access….

• STOA as per Hon. MERC TOA/DOA Regulation 2016
• SLDC

is Nodal Agency for granting

• pen

access for EHV transmission system users

• OA consumers connected to 33kV and below voltage level

respective DISCOM is the nodal agency for granting Open Access.

• Around 250-300 applications per month were processed manually.
• MSLDC being the first Load Dispatch Center to develop Web

based STOA software on cloud platform.

• Applications are processed through Web Based STOA Software.
