Details

Since the introduction of the feed-in tariff (FIT) scheme in 2010, an increasing number of consumers have installed renewable electricity generating equipment, such as solar photovoltaic (PV) at their homes or premises. In some cases the import supply meter, which measures the electricity a consumer uses from the grid, is being affected by this onsite generation. This sometimes results in inaccurate meter readings that can lead to billing issues and affect the accuracy of electricity settlement.

This is a complex problem which interacts with different parts of the electricity system. Identifying and resolving the faulty meters requires cooperation from different industry parties. The Office for Product Safety and Standards (OPSS) believes this has led to gaps in identifying and then correcting problems. OPSS welcomes the proactive steps that have been taken already by industry participants to resolve this issue going forward.

This joint letter sets out the issues as we understand it and clarifies the current obligations and expectations on industry parties.
