Local Generation Workshop - Powering Sydney
- 1. Local Generation Workshop: 25 September
- 2. Workshop Summary The workshop held on 25 September 2014 brought together a range of organisations and experts to explore local generation as a possible initiative to form part of the solution for the Powering Sydney’s Future Project. Approximately 50 representatives and experts gathered to hear about how local generation could form part of the solution. Workshop participants included representatives from consumer advocacy groups, academics, government representatives, regulators, large energy users, solution providers and other electricity networks. Participants were involved in interactive sessions to provide feedback on the local generation initiative and how existing barriers could be overcome.

- 11. SLIDE 11 OVERVIEW Local generation from the regulatory perspective • George Huang – AER / AEMO o Regulatory matters • Cath Chalmers – AEMO o Connection and Registration matters
- 12. SLIDE 12 PROJECT AND REGULATORY BACKGROUND Overview: • TransGrid – inner Sydney electricity supply solutions • TransGrid – plan NSW transmission network • 2 proposed network options: replacement cost efficient alternative • Objective: identify most economic solution MUST consider alternatives to network augmentation
- 13. SLIDE 13 WHERE DOES THE AER FIT IN? • TransGrid must undertake Regulatory Investment Test for Transmission (RIT-T) identify option to meet inner Sydney supply needs, and maximise net economic benefits • AER ensures compliance with the RIT-T: Focus is on compliance (not the ‘right’ option) AER not responsible for health, environmental and safety concerns, etc. Potential dispute resolution role Separate from the revenue determination process
- 14. SLIDE 14 OVERVIEW OF THE RIT-T • Economic cost-benefit assessment • Principles - economic efficiency, competitive neutrality, transparency • 3 stage process with 2 consultation stages • TransGrid must consider all credible options – options which meet the inner Sydney supply requirements that are: o Commercially and technically feasible o Can be implemented in sufficient time (does not need to be committed) • Options can consist of combination of network and non-network alternatives (i.e. local generation combined with network augmentation)
- 15. SLIDE 15 KEY TAKEAWAYS • The AER has an active role in this space and will be monitoring this RIT-T process (as it does for all RIT-T’s) and updates in TransGrid’s annual planning report. • RIT-T consultation requirements are a minimum • Collaborative process – TransGrid is required to look for the best option • Don’t leave issues until the end, it is better to work through issues during the consultation process. • If TransGrid or participants have any issues, please talk to the AER. In the first instance, please email aerinquiry@aer.gov.au.

Editor's Notes
- JASMINE I would like to welcome everyone here this afternoon to the Powering Sydney’s Future local generation workshop. In response to feedback from stakeholders TransGrid is hosting a series workshops to provide an opportunity for more in-depth discussions. My name is Jasmine Hoye and I am from Newgate Research. I will be your facilitator this afternoon. I would like to start by saying that those of you who joined us at this morning’s session may feel these introductions are a little repetitive. However we do have some new faces so please bear with us while we go through the introductions. I’d like to run through today’s agenda and how things will work this afternoon. Firstly a few housekeeping matters before we start: It would be appreciated if you could turn your mobiles to silent, if not off. If you do need to take or make a call it would be great if you could just pop out into the foyer area. The bathrooms are just [give directions], please feel free to duck out at any time. Exits
- JASMINE This afternoon’s workshop focuses on Local Generation. Over the next hour, we are going to hear a few presentations, and then we’ll spend the rest of the session getting your feedback, covering what you see as the barriers to local generation and the opportunities for overcoming them. We’ll start with an introduction by Stephen Clark from TransGrid. There will then be a joint presentation with George Huang from the Australian Energy Regulator and Catherine Chalmers from the Australian Energy Market Operator who will provide an overview of the regulatory process required for local or embedded generation connection. Then we’ll hear from the Co-Chair of the Better Buildings Partnership, Jamie Loader about a recent example of embedded generation in the Sydney CBD, 101 Miller Street. Lastly, Rachele Williams from Ausgrid will provide an overview of some recent Ausgrid findings about local generation in the CBD.
- STEPHEN Welcome everyone here to local generation workshop and thank them for their ongoing participation in what TransGrid thinks is an exciting project and an exciting process I will briefly introduce the Powering Sydney’s Future project, which many of you may already been familiar with and provide an overview of how local generation may fit in the ultimate solution From the initial stakeholder forum held in June and from what the occurring in the industry at large, TransGrid is cognisant that local generation will continue to be a consideration in future planning
- -TransGrid’s overall network and focus on the significance of the inner Sydney network Aware of consumer and stakeholder expectations Currently, approximately forty 132 and 330 kV cables supply electricity to offices, warehouses, universities and residences in inner-west Sydney, Sydney CBD and eastern suburbs The seven LGAs that are being catered for in the Powering Sydney’s Future project consist of approximately 650k residents and generate approximately 27.4% of the state’s GDP. Parts of the existing network supplying the inner Sydney area are approaching the end of their service life and we need to start planning now for the future. Over a dozen (15) cables are being retired over the next decade. They are all over 35 years old. - Non-network options are area specific Primary target areas for non-network initiatives are shaded Other areas such as St George area also effective Note: Leichardt, Rozelle and areas to its west and north are broadly 0% effective.
- 3% curtailment 11:15 am to 5pm 1% (1pm to 5pm) 4% (10:45 am to 5pm) Very long period of peak demand – Large variety of customers in the area, commercial, industrial, residential with different behaviours driving peak demand. As a result, the mix of these drivers is a very long extended period of peak demand. Emphasize long peak demand period. DR must be capable of deployment over this long period, but the portfolio could be made up of different types of DR, over different periods, all contributing to reducing this peak. Peak is primarily driven by commercial cooling equipment (at offices, hotels, universities etc.) Residential cooling will contribute somewhat (school children arriving home from school, part time workers, retired, non-working residents), but cooling equipment typically comes on after 5 as workers arrive home so an energy efficiency focus from TransGrid may not necessarily target these and would instead focus on commercial and industrial customers in the area.
- What we do know is that parts of the existing network supplying the inner Sydney area are approaching the end of their service life and we need to start planning now for the future. Planning inner Sydney’s future electricity network provides an opportunity to consider a range of initiatives. Project concurrently investigating multiple initiatives to develop a progressive and cost-effective solution. Explain why we are looking at these different initiatives. Explain benefits of deferring large investments. Touch on each initiative and explain that no specific decision on a solution has been made. Builder of last resort: ongoing testing/review of underlying assumptions and solutions allows more responsiveness to changing environment. considering all alternative and how they can play a part in the solution or play a part in better informing forecasts
- So what is local generation? Local generation can be defined as generation of electricity through distributed sources of energy for use within close proximity. Local generation can include: Existing backup small- scale generators in commercial precincts; Brand new generators; Cogeneration and tri-generation; and Renewable systems, if have a storage component in order to supply at peak demand times. Co-generation and tri-generation plants can be used in peak times as local generation sources to reduce peak. The 101 Miller St case study would be one to note in this case. There are numerous existing backup local generators across commercial precincts including shopping centres, offices and hospitals that can be used in peak times. Solar panels such as the 990kW Ikea has announced will contribute to peak reduction in summer. TransGrid has installed polycrystalline solar panels at its Wallgrove site this year as part of the iDemand project Energy storage systems such as the 400kWh lithium polymer batteries (pictured) and installed at Wallgrove can also reduce peak
- Emphasise the need for local generation to be within the most effective areas for the project in CBD
- I am Jamie Loader, Co-Chair of the Better Buildings Partnership Environmental Working Group. In my normal daily life I also am National Operations and Sustainability Manager for Brookfield Australia. We have been asked by Transgrid to provide you a couple examples of local generation and grid connection capabilities at commercial building scale and some of the challenges and enablers for further work in future.
- The Better Buildings Partnership is a collaboration of leading property organisations (institutional landlords, developers, universities, property managers and industry bodies/government). We have targets for energy, emissions, water and are developing them for operational and fitout waste. Many of these targets match the City of Sydney’s ambitious Sydney 2030 targets, including a 70% emissions reduction based on 2006 baseline. As of FY13 we: control 2.5million square metres net lettable area (FY13) evidenced $25million annual savings from avoided electricity costs delivered 4.4% average emissions reduction p.a. (from FY06) installed 10MW local cogeneration capacity (Sydney CBD) (does not include stand-by generators)
- Context for why we are here today: Transgrid is engaging on network upgrade options with the community (and BBP is happy to be a part of this) Since FY06 City of Sydney has seen declining electricity demand BBP has seen a 27% reduction in energy demand This demand reduction has happened despite growth in our portfolio and continued development in the City. This is consistent with the broader National Electricity Market trends and current projections by some experts project this decline to continue with the rise of electricity prices, renewable options and other factors.
- This map shows a snapshot of current existing capacity of local generation in the CBD. It is not exhaustive (eg. Westpac Kent Street Office and Barangaroo missing off here). The BBP alone has over 10MW of cogen/trigen capacity currently installed and is in the process of investigating/installing more. The installation is commercially difficult for reasons we will outline in the first case study. This map does not show the significant stand-by backup generation in prime-grade offices throughout the city that are rarely switched on.
- 101 Miller Street is located in North Sydney owned by BBP Member Mirvac and another organisation. One of the largest office towers in North Sydney, targeted and delivered a 5 Star NABERS rating as part of upgrades in 2007-08.
- Don’t spend too long on this, but important to note: Energy Efficiency was the first action taken by the building in its upgrade and included standard modernisations that many prime assets across Sydney CBD and North Sydney have now undertaken.
- The building was one of the first trigeneration installations in Sydney CBD/North Sydney for a commercial building of its size Trigen sizing for base and tenancy loads was necessary to achieve the targeted 5 Star NABERS Rating according to the modelling A BOOM contract was signed with Cogent, with key requirements for the system including: Working closely with Ausgrid on the connection specifications with the grid (the system can work in island mode) Assurance on the EPA NOx standards Smooth installation for a complex project – space constraints, tenancy and building system interaction
- The system is fully integrated with the building, with bms prioritising energy usage from the trigen over the grid and managing the load build-up for island mode.
- The team identified multiple challenges to the installation and operation of this, including standard space/access and integration challenges, but to focus: Regulatory challenges required a number of approvals with the Council, EPA, Ausgrid and Jemena as gas supplier Commercial challenges included the contracting and operation of the plant (BOOM for 12 years with Cogent was settled) Balancing how the load would be sized – integrating with tenant needs, base building alone, peak reduction alone, etc. Gas price uncertainty and hedging against future energy price increases was an important consideration. (Cogent manage the gas and just bill the energy to the building and tenant, so gas prices were not a consideration for Mirvac in this case) Connection arrangements with the meter and interface with the grid were vitally important.
- Key learnings Embedded generation does not take the place of energy efficiency and building management/tuning. The BOOM contract enabled an on-sell to tenants (Cogent are an energy retailer) Industry rating tools affect decisions on this (NABERS/CBD do not recognise export, import low-emissions energy) The Grid connection options significantly affect the business case for local generation, eg. If we owned a building across the street the current regulations do not adequately acknowledge the savings for our connecting the two buildings, or even within the building for on-sell to tenant customers. BBP has other instances showcasing these challenges and innovative ways to try to overcome them, like 8 Chifley and Coca-Cola Place. Other systems are sized to operate purely behind the meter (leading to smaller systems being specified) and sometimes never get switched on. We have options for what it would like if we had a better environment for local generation and grid connection with our second case study.
- We have options for what it would like if we had a better environment for local generation and grid connection with our second case study. 108 St Georges Terrace in Perth, major upgrade works in progress (2 phases) with targeted 4.5 Star NABERS rating outcome.
- In the SouthWest Interconnected Scheme (SWIS Grid) local generation is rewarded when connected to the grid for demand response and other purposes. Funds via demand response program enables the business case for local generation or upgrades, which has broad-reaching benefits beyond just the program participation. A number of strategies to employ depending on the asset: Efficiency like chilled water temperatures, fan speeds Embedded Generation via standby generators or cogen/trigen On-site renewables via battery storage Etc Key point is that there are many strategies within buildings that are sited directly where demand is highest (not out hundreds of KM away) that provide certainty and confidence for demand response.
- In summary, there are some key enablers to increased uptake of local generation. The network providers, local generators, our customers and the community share a want for better environmental and economic outcomes. We have big opportunities with this if we had more flexibility, lower hurdles and delays and greater certainty on our returns for upgrade works. There are a number of modernisations we would like to see to the rules, but the key 2 changes are: A local generation credit tariff: Local generators should be able to team up with FRMPs to sell their output to willing local buyers at a fairer price than current Similar to UK model (have similar electricity market structure) Subsidiary selling as part of retailer exemption rules
- Thanks and if you have further questions see contact details for above
- JASMINE We have heard a lot about local generation, including some of the successes, the challenges and what is being done at an industry level to facilitate greater up-take. There is also a lot of experience in the room from people who have tried or are in the midst of trying to get local generation implemented in their buildings. This part of today’s workshop is aimed at extracting your knowledge and applying it to the Powering Sydney’s Future Project. We will be working in table groups for the next 30-40 minutes and working through a series of key areas to focus on identifying the barriers and the opportunities for each. Your table facilitators will guide the discussion and you will spend about 8-10 minutes noting down the barriers and opportunities to overcome these barriers for each of these factors: Cost Technical Regulatory Social/environmental As a group you will then indentify the top 3 priorities for each barrier (i.e. the biggest or most significant barriers), and the top 3 opportunities for overcoming the barriers – which may be different from the top 3 barriers. Theses will later be shared with the wider group.
- - Early engagement: already commenced (local councils, this forum, other key stakeholders); reaching out to community next -Options Review: ongoing investigations on all initiatives, with a RIT-T process commencing this year. -Network Support Market Development: to develop market interest; RFPs -Environmental Assessment for cable option: critical to ensure a new cable (network infrastructure) remains an option. Will involve finalising cable route and submitting Preliminary Environmental Assessment (timing- after RIT-T has commenced this year) NO INVESTMENT DECISION MADE
- Close workshop with this slide Many thanks for your feedback today. Webpage will be regularly updated. Today’s presentations will be available on the website in the next few days. Welcome feedback and will tailor engagement approach to address specific needs.
