The Australian Energy Regulator (AER) today released its assessment of the annual expenditure claims for 2019–20 made by Ergon Energy, Energex and SA Power Networks under the current Demand Management Innovation Allowance (DMIA) scheme.
The AER has approved $3.8 million of expenditure by these Distribution Network Service Providers (DNSPs) on 21 demand management projects.
The DMIA scheme funds research and development projects to be tried by distributors to reduce or shift customer demand in order to avoid or defer network augmentation.
The projects may target a reduction in peak demand or broad-based demand. Where projects are successful, they are able to be incorporated into business as usual management practices for DNSPs. This reduces the reliance on more costly infrastructure and thereby reduces network charges.
Our assessment provides insights into the total value of expenditure approved and the type of projects the scheme has delivered. The projects varied in both their nature and scale. In the most recent period, 52 per cent of expenditure relates to stand-alone power systems, 22 per cent on research and 6 per cent on residential battery storage.
The allowance is provided to each DNSP in the form of a fixed allowance for each regulatory period. If distributors do not spend their DMIA in full, the underspent amount is deducted from the expenditure allowance for the next regulatory period. If the allowance is overspent, the distributor must meet the higher expenditure itself and cannot recover this from its customers. In the recent period, Ergon Energy and Energex are required to return $3.2 million to their customers.
