1 CENTRAL ELECTRICITY BOARD Small-Scale Distributed Generation Project (SSDG) by Raj Busgeeth Ag. Snr. Engineer (SSDG Unit)

2 Overview Inception of the SSDG Project Grid Code SSDG Schemes (FIT & PECR) Feed-In Tariffs (FIT) Management of Agreements Status of SSDG Schemes Way Forward

3 Inception of the SSDG Project (1) Willingness to democratise access to CEB grid Willingness to increase % of RE in its Energy Mix Contribute in the Protection of the Environment & Stay up to date with other Utilities Decentralise Production Reduce Line Losses

4 Inception of the SSDG Project (2) Consultant appointed to draft Grid Code in Dec 08 (Govt./UNDP/CEB) Consultant appointed to work out Feed-In Tariff in Aug 09 (Govt./UNDP/CEB) Dec 2010: SSDG Scheme Ph. 1 Dec 2011: SSDG Scheme Ph. 2 + PECR Scheme Feed-in Tariffs (FIT) allocated to kick start interest in Renewables MID Fund to fund difference between FIT & CEB s Av. Cost of Production

5 Grid Code (Low Voltage) Grid Code for SSDGs up to 50 kw connected at LV Rights, Responsibilities and Conduct of parties planning to access the CEB Grid Technical Criteria and Requirements for Interconnection Standards for Compliance Protection Requirements Safety Aspects Administrative Procedures Feed-In Tariff

6 SAFETY ASPECTS SSDG Warning Sign on LV / Service Pole SSDG Warning Sign on TX Pole Visible Switch (Lockable) with Label. Accessible to CEB B SSDG Sticker on Meter Box A Fusible Cut-out & Cable Tag on Service Cable

7 PROCEDURES FOR CONNECTING TO THE CEB GRID Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Submission of SSDG Application Form Analysis of Application by CEB Request Network Details (Load Test) from CEB District Offices Applicant publishes Public Notice in Government Gazette and Two Newspapers Request Approval for Grant of Permit from MEPU if No objection from Public Grant of Undertaker Permit to applicant by CEB Applicant pays Connection Fee and Starts Installation of SSDG CEB Installs the Import/Export Meter, Production Meter, Warning Signs etc. Testing of SSDG Installation by CEB Step 9 Step 10 Step 11 Step 12 Signature of Connection Agreement Proclamation by the President of the Republic of Mauritius Commissioning (Commercial Operation of SSDG starts) Meter Reading, Invoicing and Payment

8 FEED-IN TARIFFS FOR SSDGs (1) Attractive FIT instead of Government Grant : Kick start SSDG Project To Encourage owners to keep their SSDG in Good Working Condition to get Regular Income MID Fund to fund difference between FIT & CEB s Av. Cost of Production FIT Guaranteed for 15 years Thereafter, Export Tariff = CEB s Marginal Cost of Production SSDG owner has to consume 1/3 of Energy Produced, otherwise the FIT for the following year is reduced by 15% (Greenfield Tariff) Encourage people to use Less Electricity so as to increase their income (DSM Initiative)

9 FEED-IN TARIFFS FOR SSDGs (2) Table A Preferential FIT Feed-in Tariff for 15 Years Wind Rs/kWh Hydro Rs/kWh PV Rs/kWh Micro (up to 2.5 kw) Mini ( kw) Small ( kw) Table B Greenfield FIT (15% less) Greenfield Tariff for 15 Years Wind Rs/kWh Hydro Rs/kWh PV Rs/kWh Micro (up to 2.5 kw) Mini ( kw) Small ( kw)

10 SSDG Scheme Phase 1 - (2 MW) Launched in Dec 2010 for 2 MW SSDG up to 50 kw ; Advertised thru Newspapers and CEB s Website Customer Category Capacity Allocated No. of Applications Received Equivalent Capacity Residential 1 MW MW Commercial, Industrial & Others 1 MW 76 2 MW TOTAL 2 MW MW Only first 2 MW of applications considered Applications on Waiting List considered as and when applications were Withdrawn or Rejected for Non-compliance

11 SSDG Scheme Phase 2 - (1 MW) Launched in Dec 2011 for 1 MW Advertised through Newspapers and CEB s Website Applications on Waiting List from Phase 1 considered Category Capacity Allocated No. of Applications Received Equivalent Capacity Residential 450 kw kw Commercial, Industrial & Others 450 kw Applications on Waiting List considered 1,000 kw Rodrigues 100 kw kw TOTAL 1 MW MW

12 Interest in RE from Subsidised Institutions such as Educational, Charitable, etc. Go Green and Reduce their Electricity Bill Launched in Dec 2011 for 2 MW PECR Scheme (2 MW) 2 MW allocated to Public, Educational, Charitable & Religious Institutions (PECR) Export Tariff = CEB s Marginal Cost of Production Category Capacity Allocated (kw) No. of Applications Received Equivalent Capacity Public kw Educational 1, ,045 kw Charitable kw Religious kw TOTAL 2 MW MW

13 Summary of SSDG Schemes Dec 2010 : Phase 1 Residential : 1 MW Com. & Ind. : 1 MW Dec 2011 : Phase 2 Residential : 450 kw Com. & Ind. : 450 kw Feed-in-Tariff (FIT) Subsidized by MID Fund FIT Mauritius (P1 & P2) PECR Dec 2011 Capacity of 2 MW allocated Public, Educational, Charitable & Religious Institutions Export Tariff = CEB s Marginal Cost of Production Capacity of 100 kw allocated. Residential (max 5 kw) Commercial & Industrial customers. (max 10 kw) Feed-in-Tariff (FIT) Subsidized by MID Fund FIT Rodrigues Regularization of Illegal Connections Regularization of illegallyconnected SSDGs for Safety Reasons (12 Oct 2011 & 29 Mar 2013) No Export Tariff

14 Management of Agreements > Yearly Monitoring of Consumption/Production Ratio > Change of Tariff accordingly ( Preferential / Greenfield ) SIPPs > Outsorting to identify Implausible Values (Values outside Range set, Fraud Detection Mechanism) > Technical Grid Issues at PCC (Meter Faulty, Loose Connection, Inverter Faulty, PV String Faulty, RCD Faulty etc.) > Troubleshooting and Problemsolving on the CEB Network (Low/High Voltage, Neutral Alive, Rotation Problem etc.)

15 Status of FIT Scheme MAURITIUS As to date, CEB is purchasing electricity from 237 Small Independent Power Producers (SIPPs) in Mauritius. FIT Mauritius No. of SSDG Installations Equivalent Capacity Commissioned MW RODRIGUES As to date, CEB is purchasing electricity from 17 Small Independent Power Producers (SIPPs) in Rodrigues. FIT Rodrigues No. of SSDG Installations Equivalent Capacity Commissioned kw

16 Status of PECR Scheme MAURITIUS & RODRIGUES As to date, CEB is purchasing electricity from 40 Small Independent Power Producers (SIPPs) under the PECR Scheme. PECR Scheme No. of SSDG Installations Equivalent Capacity Commissioned kw

17 Summary Total FIT, PECR & No Tariff As at today, a Total of 301 SSDGs have been commissioned for an equivalent Capacity of 2.8 MW. Scheme No. of SSDGs Equivalent Capacity (kw) FIT Scheme Mauritius 237 2,051 FIT Scheme Rodrigues PECR Scheme SSDG No Tariff TOTAL MW

18 Energy Exported by SIPPs Energy Exported by SSDG (FIT) and PECR Categories ( 3.6 GWh ) 2,500,000 2,239,778 Energy Exported (kwh) 2,000,000 1,500,000 1,000, ,000 1,132,098 2, , Energy exported (kwh) 2, ,619 1,132,098 2,239,778 Installed capacity (kw)

19 Way Forward After first 200 SSDG Installations were Commissioned, a Grid Impact Study was conducted. No significant Impact was observed on the CEB Network due to these 200 SSDG Installations. A Consultant was appointed in 2014 to determine the overall Grid Absorption Capacity of RE in the CEB Network. The Report is presently under study by the CEB/Govt. to determine Way Forward.
