What are the payment schemes available for consumers generating solar energy?

Types of Payment SchemeDetails  
Simplified Credit Treatment Scheme (SCT) EMA has simplified the market registration process for Non-Contestable Consumers (NCC) to directly register with SP Services.

Under the SCT, NCCs that sell any excess energy to the market will be paid at the prevailing tariff minus grid charges.

More information on SCT can be found here

Enhanced Central Intermediary Scheme (ECIS)EMA has introduced the ECIS where Contestable Consumers (CCs) can register with SP Services directly, thus reducing regulatory barriers and administrative matters.

Under the ECIS, CCs that sell any excess energy to the market will be paid at the prevailing half-hourly wholesale energy prices

Register as a Market Participant (Non-Exporting)
EMA has introduced a new class of Market Participant (Intermittency Generation Sources Non-Exporting) category. Under this category, consumers will undergo a streamlined market registration process where they are not required to provide credit support or to submit generation meter readings to Energy Market Company (EMC). Consumers will not be paid for injecting any excess energy to the grid.

Consumers are required to pay EMC an estimated fixed charge on the IGS capacity only every six months. This will be based on a standardised IGS Generation Profile for all consumers.

Register as a Market Participant
Consumers with solar installations will need to register as a Market Participant with Energy Market Company, subject to the relevant Market Rules. Any excess energy solar sold back to the market will be paid at the respective nodal price.
