In May 2019, DCC consulted on the System Capacity Testing Approach Document for SMETS1 Services ('SCTAD')
System Capacity Testing is a Test Phase that demonstrates that the operational performance of the Modified DCC Total System is not adversely affected by the introduction of SMETS1 Services, and that the SMETS1 Services will operate at the requisite performance levels.
On June 27 2019, DCC concluded on the consultation and submitted the SCTAD and conclusions document to BEIS for approval.
