181 of the Electricity Act 2003 (36 of 2003) and all other powers enabling it in this behalf, this Commission made Chhattisgarh State Electricity Regulatory Commission (Renewable Purchase Obligation and REC framework Implementation) Regulations, 2021 (here after called "the Principal Regulations"). These regulations were applicable from April 01, 2021. In these regulations, obligated entities and minimum quantum.of electricity to be procured by obligated entities as percentage of total consumption for three years starting 2021-:22 have been specified.
Ministry of Power vide it's letter dated 17.11.2017 issued guidelines to use 5-10% blend of biomass pellets made, primarily, of agro residue along with coal, in all fluidized bed and pulverized coal based thermal power plants except those having ball and tube mill, of power generating utilities, public or private located in India. On 08.10.2021, MoP revised the policy for biomass utilisation for power generation through co-firing in coal-based power plants in which all coal based thermal power plants of power generation utilities with bowl mill, ball & rice mill and ball & tube mills have to use mandatorily 5% blend of biomass pellets on annual basis. Meantime, Central Electricity Authority of India (CEA) issued an advisory on
24.11.2017 to all the stakeholders for utilizing biomass in coal based thermal power plants.
Subsequently, in order to promote co-firing of biomass in thermal power plants, Ministry of New and Renewable Energy (MNRE), Government of India, vide its notification dated 26.9.2019 has clarified that the power generated from co-firing of biomass in thermal power plants is renewable energy and is eligible for meeting non-solar Renewable Purchase Obligation (RPO) and has requested Central Commission to formulate and notify the procedure/methodology for quantifying the energy produced from biomass in biomass cofired thermal power plants in ·a reliable 'and accurate manner'. . . . .. - .. .
Central Commission, vide order dated 18.02.2020 in suo-motu petition 12/SM/2019, has prescribed methodology for estimation of electricity generated from biomass in biomass co fired thermal power plants. In this order the Central Commission observed that biomass can also be used in thermal captive power plants and the methodology shall be applicable to the captive power plants using co-firing of biomass.
The Commission, vide order dated 20.04.2022 in P No. 24 of 2022, has held as follows;
"6. From the above discussion it is clear that this matter can be resolved only making suitable amendments in CSERC (Renewable Purchase Obligation and REC Framework implementation) Regulations, 2021, for which regulatory process is required. We direct regulatory process be initiated by the concerned section."
1522 (6) i?cffi,(-l•I~ ~, ~ 31 ~ 2022 Recently, Ministry .of Power vide it's order dated 22.07.2022 and its corrigendum dated
19.09.2022 has issued trajectory till 2029-30 for RPO and energy storage obligation. This · trajectory has been specified for periods beyond 2021-22. First proviso of para 4.3 of -Principal Regulations 2021 specifies as follows;
"Provided that RPO levels for the year 2022-23 & 2023-24 shall be as specified above or MoP/MNRE trajectory to be_ specified, whichever is higher. " _ In view of the above, the Commission is of opinion to align the RPO in line ,with MoP circular till. the year 2029-30.
In pursuance of the Principal Regulations and to give effects to the foregoing developments, - ~e Coi:nmi_ssioii hereby makes the following regulations to amend the Principal Regulations.

7. New Annexure to be added as Annexure-A Methodology estimation of electricity generated from biomass in biomass co firing coal based thermal power plants, including captive and co-generation power plants co-firing biomass The methodology specified hereunder is to be followed by generating companies, State Load Dispatch Centre, State Agency for estimating electricity generated from biomass co-firing coal based thermal power plants, including captive and co generation power plants co-firing biomass.
Step-1:
I. The electricity generated from biomass shall be estimated at generator terminal on monthly basis in accordance with the following formulae :
Eb(G) = [(Qb x Gb) I ((Qc x Ge)+ (Qb x Gb) )] x E(Gn Where, Eb(G) = Electrical energy generated by biomass at generator terminal during the month (kWh);
Qb = Quantity of biomass consumed during the month (kg) Gb = Weighted average Gross Calorific Value (GCV) of biomass consumed during the month (kCal/kg},_ as specified in the CSERC RE Tariff Regulations E(GT) = Gross electrical energy generated at generator terminal during the month (kWh) Qc = Quantity of coal burnt during the month (kg) Ge = Weighted average GCV of coal burnt during the month (kCal/kg)
2. The product (Qb x Gb) represents heat (in kCal) input through biomass during the month and shall be estimated on monthly basis by applying the following formulae:
. Qb . ~ Qb __ (k.C::iµ). :-= _{Qpt::i;iing palance qf biomas~ (kg} x _\\'.eighte_d .~verage _GCV of opening balance of biomass (kCal/kg)} + {q~ty,9.fbiomass received during the month (kg) x weighted average GCV ~fJ~i~i83:~J;:reeehred during the month (kCal/kg)} - { closing stock of biomass (kg) x weighted average GCV of the closing balance of biomass (kCal/kg)}.
3. The product (Qc x Ge) represents heat (in kCal) input through coal during the month and shall be estimated on monthly basis by applying the following formulae:
Qc x Ge (kCal) = { Opening balance of coal (kg) x weighted average GCV of Opening balance of coal (kCal/kg)} + { quantity of coal received during the month (kg) x weighted average GCV of coal received during the month (kCal/kg)} By Order of the Commission Sd/- (S.P. Shukla) Secretary.
1522 (10) i?cffi,(-l•I~ ~, ~ 31 ~ 2022 - { closing stock of coal (kg) x weighted average GCV of the closing balance of coal (kCal/kg)} Step-2:
4. · The ex-bus electrical energy generated by using biomass shall be estimated on monthly basis by applying following formulae:
Eb (ex-bus) = Eb(G) {1-[(E(GT) - ESO)/E(GT)]} Where;
Eb (ex-bus)= Electrical energy generated by biomass ex-bus during the month (kWh);
Eb(G) == Electrical energy generated by biomass at Generator terminal during the month arrived at Step-l(kWh);
E(GT) = Total electrical energy generated at generator terminal during the month (kWh);
ESO = Total energy sent out (ex-bus) during the month (kWh).
5. The generating company shall provide information to the beneficiaries and State . Agei;icy related to biomass uses and monitoring mechanism/power to get statistics for the use of biomass fuel shall be as per provisions specified in prevailing CSERC RE Tariff Regulations for .. biomass and co-generation plants.
State Agency shall verify electricity generated from biomass co firing in power generating plants.
Monthly fuel and GCV accounts as maintained by generating station shall be made available to authorized representative/s of beneficiaries and SLDC on demand.
