Decision
After considering the feedback received, EMA has decided to allow Market Participants to aggregate multiple standalone IGS and register them as pseudo GSFs under the conditions as setout in the attached paper.
Update
The consultation has closed for comments.
Consultation
The Energy Market Authority supports the adoption of solar energy in Singapore. In ensuring fair and sustainable growth of solar, EMA continues to make enhancements to our regulations to facilitate the entry of solar photovoltaic (PV) installations into the National Electricity Market of Singapore (“NEMS”).
EMA has received industry request to allow Market Participants (“MP”) to register multiple distributed standalone (i.e. direct grid-connected) Intermittent Generation Source (“IGS”)installations with the Energy Market Company (“EMC”). However, there is an inherent limit to how many unique number of facilities that thesettlement engine can effectively handle (i.e. about 180 facilities estimated by EMC). If EMC were to proceed with registering every IGS installation as individual Generation Settlement Facilities (“GSFs”), as per current practice, the limit would be quickly breached. This can result in a longer settlement processing-time for the settlement engine and consequently impact the settlement operations of the wholesale electricity market, unless the settlement engine and related systems can be upgraded.
This consultation outlines the proposed solution which EMA has worked with the EMC and the Market Support Service Licensee (“MSSL”) to support the registrations of multiple distributed standalone IGS installations without requiring complex system changes.
