Upcoming Enhancements

IPM seeks to ensure fair cost allocation of reserves and regulation charge to all generation sources, including solar. IPM can ensure the sustainability of solar deployment by ensuring it prices in the relevant costs it imposes on the electricity system.

Solar deployment in Master-sub setup

We have received feedback on the existing constraints that buildings under a Master-sub setup face. We are working towards removing these constraints, such as enabling the Landlord of a master-sub to be contestable, as well as for solar installed on master-sub buildings to be paid for excess solar sold to the grid.

Currently, there are physical work-around solutions (i.e. connect solar directly to SPPG substation or connect solar main switchboard to consumer main switchboard before connecting to the grid), which may be workable for some buildings. You may refer to the terms and conditions for the direct connection to grid method here. 

In the longer term, removing the constraints for master-sub buildings via system changes will help to accelerate solar deployment in such settings.

Implementation of Solar Aggregator Model

This is to allow solar aggregators to receive consolidated export payments from their solar PV panels and receive metering data from SP (instead of the current process which is through individual customer)

This enhancement will make it administratively easier for solar leasing companies to receive payments and data from their solar consumers.

Allow nomination of third parties to receive direct payments from SP in lieu of consumers for energy exports from solar and embedded generation

This is to make it easier for solar companies and consumers by providing options for consumers to allow a third party to receive solar payments on their behalf. This will make it administratively easier for installations under the solar leasing models.

Allow consumers to have multiple embedded generation units and leasing companies on their sites

This is to allow consumers to (a) install different types of new technologies on their sites; and/or (b) lease them from different entities. Current system design of SP’s billing system only allows for payments to one leasing company, but once this enhancement is implemented, consumers may choose to engage multiple lessors overtime.
