FACTORS AFFECTING GENERATION

IRONIES AT SITES • Unqualified Contractor • Roof Structure Strength • Proper Access For Material Supply over roof • Working without any design • Unalignment of Panel in each row • Installation Of Inverter • Mounting Area for Lightening Arrestor • Leakages at roof • Local Groups like Mathadi

NET METERING POLICY

NET METERING • Net Metering Arrangement” means an arrangement under which a Roof-top Solar PV System with Net Meter installed at an consumption end in your premises & will deliver surplus energy after adjustment to MSEDCL ( Energy Credit ) • The Final Electricity Bill of the Month = Units Consumed – Units Generated by Solar • At the end of Financial Year the excess energy if any due to credit will be purchased by MSEDCL at Average Pooled Power Price

MODALITIES OF NET METERING • Capacity of Solar Rooftop : Should not exceed sanctioned load or contract demand • Distribution Transformer : The SRT Capacity shall not exceed 40% of distribution transformer rated capacity. • Distribution Licensee may allow Net Metering Exceeding 40% capacity upon detailed load study • HT Consumers may install Rooftop system at LT bus bar system but Net meter to be installed at HT side of transformer

NET METERING – GRAPHICAL PRESENTATION

ELECTRICAL SYSTEM CHANGE • As per Policy the cost of Net Metering is to be borne by MSEDCL • But Consumer may opt to change the metering as per approved Specification at own expenses. • No change required in internal electrical systems

NET METERING GUIDELINES • Commercial circular 258 • Application Form • Net Metering Procedure • Net meter connection agreement • Net meter Specifications for 1 phase LT, 3 Phase LT, LTCT operated, HT-CT Operated Etc. • Approved makes for Net meters: Secure, L& T , Genus

NET METERING PROCEDURE • Application form with 1. Technical Specifications 2. SLD 3. Electricity Bill 4. Paid receipt. • Where To submit? Application to be submitted to the office of the respective nodal officer/ authorities authorized for billing

NET METERING PROCEDURE • Processing fees • SLD Verification • Technical feasibility Report • Letter for Testing of Meters. • Test Reports from Testing division • Plant Installation Testing • No Objection Certificate after testing • Agreement between consumer and MSEDCL. • Net Meter Installation • Verification Report
