Energy Network Transformation Dr. Stuart Johnston Executive - PowerPoint PPT Presentation

Energy Network Transformation Dr. Stuart Johnston Executive Director, Assets and Network Transformation

Overview • ENA – scope and current focus • Disruptive change driven by customers and technology • Network businesses are responding • Network Transformation Roadmap project

ENA Members The peak national body representing gas distribution and electricity transmission and distribution businesses throughout Australia. Twenty-six electricity distribution and transmission and gas distribution network companies are members of ENA.

Energy Networks Association • Energy networks are the lower pressure gas pipes and low, medium and high voltage electricity lines that transmit and distribute gas and electricity from energy transmission systems directly to the doorsteps of energy customers. • More than $100 billion in assets and almost 15 million customer connections nationally • Total line length of distribution infrastructure is more than 900 000 km • Key focus areas include: – the national and state government policy and regulatory environments – key technical issues such as network safety and security of supply, skills and training, reliability and power quality and energy efficiency .

Technology is disrupting the traditional Energy business model In many aspects the pace of change in Australia is ahead of other countries Australian Energy businesses must act now

Upending our Energy System • AEMO: Solar PV capacity to increase 500% to 2035 - Output ranging from 9.3% (NSW) to 28% (SA) of Energy - Shifting peak to 7.30pm in SA and Qld • Within 10 years, Solar PV output could exceed minimum demand in South Australia

Expected costs of solar panels and storage continues to drop The key transformation drivers – competitive on-site generation and storage – have each strengthened their competitive position since 2013 by about 20% 3000 600 Solar 2013 estimate Solar 2015 update 2500 500 Batteries 2013 estimate (right axis) Batteries 2015 update (right axis) 2000 400 2015 $/kWh 2015 $/kW 1500 300 1000 200 500 100 0 0 2015 2020 2025 2030 2035 2040 2045 2050

Converging costs of centralised generation technologies SOURCE: Australian Power Generation Technology Cost Study 2015

Australia leads the world in Germany has the highest solar the penetration of generation per capita (0.47kW). household solar PV Only 3.72% of dwellings have rooftop solar. By contrast, Australia places 6th on the solar generation per capita league table (0.19kW); and has the highest penetration of household PV. Australia has significant untapped potential for grid scale PV.

Future Grid Forum modelling update Set and forget Leaving the grid Rise of the ‘Prosumer’ Renewables thrive

Electricity consumption will be flat to rising • To project consumption, we start with AEMO and IMO’s projection, and adjust for each scenario’s on-site generation and electric vehicle adoption

Peak demand growth will also be subdued • To project peak demand, we start with AEMO and IMO’s projection, and adjust for each scenario’s battery storage and other demand management adoption

Grid under-utilisation is still a risk • Declining utilisation remains a risk but these results are around 5-10 percentage points better than in the 2013 modelling in the three worst cases, due to improved outlook for demand management

The outlook for networks costs is improved • The improved outlook for utilisation means that the outlook for network costs has improved, with long term costs 3-10c/kWh lower across the scenarios

Cumulative system expenditure shares are diverse

Updated Future Grid Forum scenario analysis Fourth key finding • The updated scenarios continue to reflect electricity networks performing an evolving range of critical roles by 2050 supporting diverse energy use and services for customers Networks roles Networks grow range from modestly under leading to all scenarios enabling Urban grid disconnection A wider range remains of customer needs are met uneconomic until late 2030s

Customer-orientation of Networks • Future electricity customers may: – be increasingly heterogeneous in their expectations – be diverse across a broad vulnerable—engaged— empowered spectrum of market segments. – continue to value solutions that provide secure and reliable electricity for an increasingly digitized and automated lifestyle and the expanding role of electric vehicles; and – In some cases be willing to trade-off aspects of services that were traditionally standardised in return for a financial benefit.

Customer-orientation of Networks • Future market segments are not perfect ‘predictions’ of customers in 2025 but do enable future strategic options to be explored in detail • An increasingly competitive operating environment means that a strong customer orientation will be vital for network businesses and their ‘value-network’ partners to: – Comprehend and anticipate changing customer expectations; – Optimise existing services to foster social license , trust and loyalty ; and, – Innovate new electricity solutions and business models , often in concert with value network partners.

Challenges and Opportunities of Distributed Energy Resources Integration of Distributed Energy Resources requires a careful operational response to challenges such as voltage management, frequency regulation and network stability. However, well-integrated DERs can also provide solutions for addressing these network challenges and improving network efficiency. This is likely to require: • New regulatory frameworks; • Enhanced standards; and • Commercial responses which unlock the potential of energy storage, demand response services and power electronics solutions.
