Mathematical Formula & Power Consumption Guide
Multi-Cycle Normalization Rule (Zero-Error Architecture)
Electricity distribution companies (DISCOMs) in India operate under different billing cycle durations:
- Monthly (30 Days): Delhi (BSES BRPL), Maharashtra (MSEDCL), Uttar Pradesh (UPPCL Urban), Karnataka (BESCOM), Telangana (TGSPDCL), Assam (APDCL).
- Bi-Monthly (60 Days): Tamil Nadu (TNEB), Kerala (KSEB), Punjab (PSPCL).
- Quarterly (90 Days): West Bengal (WBSEDCL).
To compare tariffs fairly without mathematical distortion, monthly consumption ($U_m$) and load ($L$) are normalized as follows:
- Monthly DISCOMs: Direct calculation: $\text{Bill}_{\text{Monthly}} = \text{Calculate}(U_m, L, \text{'monthly'})$.
- Bi-Monthly DISCOMs (TNEB, KSEB, PSPCL):
- Equivalent 60-day consumption: $U_{60} = U_m \times 2$
- 60-day bill: $\text{Bill}{60} = \text{Calculate}(U{60}, L, \text{'bimonthly'})$
- Normalized Monthly Bill: $\mathbf{\text{Bill}{\text{Monthly}} = \text{Bill}{60} \div 2}$
- Quarterly DISCOM (WBSEDCL):
- Equivalent 90-day consumption: $U_{90} = U_m \times 3$
- 90-day bill: $\text{Bill}{90} = \text{Calculate}(U{90}, L, \text{'quarterly'})$
- Normalized Monthly Bill: $\mathbf{\text{Bill}{\text{Monthly}} = \text{Bill}{90} \div 3}$
