32、ctoria to NSW interconnectorVREVariable renewable energy AEMO Services 2023|2023 IIO Report8Invitation to engageThe Infrastructure Investment Objectives Report(IIO Report)serves dual purposes.It sets out a least-cost pathway for developing new electricity infrastructure in NSW that meets legislative
33、 objectives,so that consumers,communities,and industry can understand and plan for the energy transformation with confidence.Critically,it also seeks to operationalise this pathway by providing developers and investors with a forward view of opportunities to secure financial support through regular
34、tenders over the next 10 years.It demonstrates that AEMO Services,with our NSW Government partners,is committed to delivering built energy.This draft report builds on our two previous IIO Reports,calling for consistent investment over the 2020s to meet NSWs minimum targets as quickly as possible.Bey
35、ond 2030,it calls for significantly greater investment in new renewable generation infrastructure than previously forecast,in order to minimise costs for NSW electricity customers.Due to the rapid pace of the energy transition in NSW,the assumptions underpinning the modelling contained within this r
36、eport are fast becoming outdated.The modelling,for example,does not include the recent announcements of delays in committed projects such as Snowy 2.0,and project developments,such as the first stage of a large-scale battery at the Eraring Power Station.Notwithstanding,we are seeking to engage on th
37、e pathway but more importantly our underpinning methodology so that feedback can be incorporated in the final version of this 2023 IIO Report published in December.As we prepare to update our modelling and publish the final version,we welcome constructive and critical input from our stakeholders.We
38、are hosting public forums during May 2023 and intend to run deep dive sessions in June 2023 based on your feedback regarding topics of interest.I also encourage you to make a written submission.Details of the consultation process are set out in section 6 of this draft report.We look forward to your
39、feedback.Paul Verschuer Executive General Manager AEMO Services 2023|2023 IIO Report9At a glance Supporting consistent,strong investment in electricity infrastructureThe IIO Report is issued every two years to set out NSWs 20-year pathway for investment in new electricity infrastructure,alongside a
40、10-year plan for conducting tenders for long-term energy service agreements(LTESAs)to support that infrastructure.While the 2022 IIO Report focussed on near-term reliability needs,the Draft 2023 IIO Report leverages updated forecasting assumptions and methodologies to provide a clearer indication of
41、 NSWs long-term electricity infrastructure needs.1The draft development pathway in this report seeks to deliver affordable,reliable,secure and sustainable electricity to NSW customers,assuming a scenario that is broadly consistent with AEMOs ISP Step Change scenario.The draft tender plan provides th
42、e market with regular opportunities to secure financial support over the next 10 years.The tenders are anticipated to support 3,000 GWh of annual generation every six months and up to 1 GW of long-duration storage capacity every year until we hit our 2030 targets.Generation:The equivalent of 3,000 G
43、Wh of annual generation every six months NSW has a legislated minimum target for the construction of renewable generation capable of producing 33,600 GWh of electricity every year by 2030.To achieve this,AEMO Services will conduct biannual tenders with the aim of supporting 3,000 GWh of annual gener
44、ation each tender,and is agnostic as to the location and mix of that generation.AEMO Services view is that this scale of investment is needed across all reasonable assumptions for future demand,coal plant retirements and network infrastructure delays.From 2030 through to 2043,significantly more rene
45、wable generation than forecast in the 2021 and 2022 IIO Reports will be needed to maintain downward pressure on prices for NSW electricity customers.The increased amount of generation infrastructure in the second decade is the result of several factors,including increased electricity demand and earl
46、ier NSW coal generator retirements.Long-duration storage:Technology readiness to be tested through annual tenders NSW has a legislated minimum target for the construction of 2 GW of long-duration storage by 2030.This is not likely to be delivered until the late 2020s,later than forecast in the 2022
47、IIO Report(due to updated assumptions regarding pumped hydro lead times and battery costs).However,these assumptions are highly uncertain and AEMO Services will continue to test them through annual tenders from 2023 to 2028.This may reveal that pumped hydro projects will be ready earlier and/or that
48、 other technologies are cost competitive.Firming:Only one tender planned at this stage AEMO Services has launched a tender for an indicative minimum of 380 MW of firming infrastructure in Q2 2023.2 AEMO Services considers that at least this much firming infrastructure capacity along with 2 GW of lon
49、g-duration storage delivered by 2030,is needed to meet NSWs reliability needs through to 2040.This view is consistent with the 2022 IIO Report and no other tenders are currently expected unless there are major market events,(e.g.delays in critical transmission infrastructure projects or announcement
50、s of early coal-fired power station closures).The proposed tenders for generation and long-duration storage are more regular than planned in the 2022 IIO Report,to provide greater consistency and certainty for the market.However,AEMO Services may recommend more or less LTESAs than the target volumes
