2. DISTRIBUTED PV and EE – partners? Competitors?
Partners against climate change and also other benefits..
Compete in LCOE, BUT ALSO to capture the customer bill savings as value of PV self-consumption is much higher than value of PV exports
Competing for bill savings not OK as PV and EE create divergent benefits
Network value is particularly important in Australia

3. Solutions? - The local network credits
Possible solutions?: more cost-reflective network pricing, DM mechanisms, storage, more cost-reflective feed-in tariffs
We explore the last one: “Local Network Credits” (LNC)
Issue here: PV exports pay full network charges but that’s not fair..
Distributed generation
Current network charges for distributed generation

4. Methodological aspects
PV+EE value with net metering in Australia, hour by hour, sum for year 2016 and escalated for 25 years
Hourly data from real PV systems, household demand and seasonal EE energy savings profiles in Australia
Time-of-Use LNCs taken from ISF study based on the non-used LRMC of the network

5. COMBINED PV+EE financial value
Adding AC-EE to households with PV reduces the PV value quite a lot
Adding LNCs to households with PV increases the PV value quite a lot
Adding AC-EE and LNCs to households with PV maintain the PV value
… and maximizes the PV+EE value
LNCs can ALSO (not only fairer FiT) remove barriers to the combined uptake of PV+EE
