Reference is made to the letters of AGM(CS)/DGM(CS&RA)/REG/7 and PUC/LI/AP19/01 dated 31st Oct 2019 requiring to revise the LCLTGEP 2020-39 submitted on 29th May 2019. The Commission requested revisions to the LCLTGEP 2020-39 submitted on May 29,2019 The PUCSL noted that the, 1. Revised plan complies with the reliability requirements of the electricity network of Sri Lanka published in terms of Section 43 (8) of the Sri Lanka Electricity Act 2. The plan has not incorporated economic cost and also not incorporated a calculation of minimum incremental cost of externalities required to change the least cost technology to justify the least cost technology as agreed in the meeting 3. The plan does not comply with the general policy guidelines issued under Section 5 of the Sri Lanka Electricity Act which describes the 50% renewable energy target by year 2030 4. CEB has not included the major milestones to justify the timelines considered for the major power plants due to be added on first 8 years of the revised plan Hence, PUCSL asked CEB to comply the above |

PUCSL communicated CEB the observation of the Commission on the Generation Plan and its decision on the plan · The draft base case plan has not adhered to the technical and reliability requirement (reserve margin requirement) of the electricity network in Sri Lanka published by the PUCSL but has prepared to an increased reserved margin. This has resulted in an over investment of USD 43 million as per the estimation of CEB. · Least Economic Cost – The plan has not incorporated the social and environmental cost, hence the cost mentioned in the plan cannot be considered as the economic cost. · The plan does not fully comply with the General Policy Guidelines which states 50% of the electricity generated in the 2030 is required to be form renewable energy sources · The Plan has considered stringent time targets for power plant implementation which may not be practically achievable which may result in procuring short term power plants violating the least cost principals
The PUCSL asked CEB to revise the plan paying importance to the published gazette on the technical and reliability data which PUCSL asked the suggestions from CEB before the publish, incorporate economic cost, comply with the general policy guidelines and asked to submit the implementation plan of the major power plants with timelines. |

Refers to the letters of PE/TECH/D/03/09 and GP/CE/101 PUCSL communicated to the Secretary that CEB did not submit any comments to the PUCSL request on amendments to the Technical and Reliability parameters (Reserve Margin and loss of load probability) and delays in power plants can be modelled in planning studies and is not required to be addressed by increasing the reserve margin throughout the planning period, which results in increase in the cost and end user tariff. PUCSL also noted that the base case plan of LCLTGEP should be prepared based on the most likely implementation targets of the power plants, as per the planning criteria published in the Gazette and any additional plants required due to any contingencies as a result of unpredictable delays of the power plants should be identified as separate contingency plans to the Base case plan, instead of increasing the reserve margin. |
