Guest Keynote

Navigating a Path To Net-Zero

Bruce Smith leads the Strategy and Planning team in Emirates Water and Electricity Company, Abu Dhabi, which is responsible for charting the route for the power and water sector achieving net-zero.  EWEC is the Abu Dhabi Independent System Operator (ISO)  but has the rare feature of also being a 'Single Buyer' meaning that not only does it plan what additions to the system are needed to achieve its decarbonisation objectives and maintain system security but it then runs a competitive auction process to contract for these services at least cost.  World record low prices for solar, gas and new water capacity have been the direct consequence of this approach.  This 'ISO coupled with direct contracting' model sidesteps many of the challenges faced by fully liberalised markets and is ideally suited to enabling an efficient and rapid energy transition where technologies and costs are evolving rapidly.  But this approach depends on a world class modelling and analysis capability and an accurate and flexible 'digital twin' of the power and water system is a critical enabler.  In this presentation Bruce explains how the EWEC planning team deploy its techno-economic PLEXOS model integrated with power system modelling in PSSE to identify and maintain its optimal pathway to achieving net-zero.

Track 2: Decarbonisation

Tomorrow's Energy Scenarios for Ireland & Northern Ireland: Using PLEXOS for the Creation and Exploration of Clean Energy Transition Pathways

Together, EirGrid, SONI and Mott MacDonald have used PLEXOS to conduct a detailed study on the future of Ireland’s and Northern Ireland's power systems -"Tomorrow's Energy Scenarios 2023". As part of an integrated team, they defined a range of credible pathways that Ireland and Northern Ireland might take to achieve a Net Zero power system. The project leverages PLEXOS’ long-term scenario optimisation planning capabilities to their greatest potential. Each scenario considers a different pathway to decarbonise the power system, how electricity demand and generation might evolve from 2035 to 2050, and how existing and future technologies will play different roles in the energy transition.

Track 1: Infrastructure & Reliability

PLEXOS Workflow Automation for German Grid Development

Together with external service providers, Energy Exemplar developed a web-interface based data processing toolchain and simulation run manager for the German TSOs - the Data Handling System (DHS).
The DHS is crucial when it comes to delivering simulations on time for the German Grid Development Plan.
The DHS manages all simulation runs and states the current status of runs to users.
It includes a graphical user interface for a simulation overview, starting simulations, input data conversion, report creation.

Track 2: Decarbonisation

Leveraging Stochastic Inputs to Model Power Price Uncertainty & Volatility to Enhance Asset Investment Decision Making

The recent gas crisis highlighted the energy markets' volatility, with unexpected supply issues and geopolitical tensions driving unprecedented power prices. Traditional deterministic models, which focus on single-scenario forecasts and long-term equilibrium, often miss these fluctuations due to their static assumptions. This creates a blind spot for extreme market events. In contrast, stochastic modelling, which considers multiple scenarios, provides a more robust framework for capturing market uncertainties and enhancing decision-making in power markets. This discussion will explore the uncertainties that need addressing for more accurate long-term power price forecasts..

Navigating the Future of Energy with PLEXOS: Case Studies from Irena's Energy Analysis

This presentation will delve into the role of PLEXOS in IRENA's analysis and planning for renewable energy integration across the globe. Featuring a series of case studies, it showcases the practical applications of this advanced simulation tool in understanding and navigating the complexities of the global energy system. The session will explore how IRENA uses PLEXOS in modelling energy system challenges, assess system flexibility, and optimising the deployment of renewable resources

Optimization of Green Ammonia Projects with Universal Class

Universal class provides capability to model all components of the green ammonia facilities, starting from renewable generation and battery storage to electrolyzers, ammonia plants, and respective storages. Whole production chain from renewable electricity to hydrogen, and then hydrogen to ammonia and other derivatives can be represented. With Universal Class we are able to optimize size of the individual components, conduct risk assessment and quantify levelized cost of hydrogen i.e. ammonia.

Track 2: Decarbonisation

Model Development for Decarbonisation of a Greek Island

Islands often have specific challenges when it comes to the electricity supply, as the grids are small and more vulnerable to instabilities. Introducing large shares of renewable power requires flexible power plants that can be turned on and off quickly as power exchange with other grids is often limited or not possible at all. A typical Greek Island scenario will be analyzed with regard to decarbonization. It will be shown how large shares of renewable power can be achieved by installing different types/combinations of flexible power plants.

Overcoming Non-Convergence of High Forced Outage Scenarios

South Africa is experiencing high unplanned failure rates of base load plant. PLEXOS is unable to achieve input/output convergence for generators experiencing 55-65% unplanned failure rates. The presentation will provide methods that the Eskom Energy Planning team have used to overcome this issue and utilise PLEXOS successfully despite high forced outages.

Development of Generation Capacities in the Light of European Energy Policies and the Impact on the Centralized Heating and Cooling Systems

The project analyzed options to decarbonize Zagreb's district heating system in alignment with the Fit for 55 package and the Paris Agreement. It focused on identifying efficient technological solutions to reduce emissions and improve resource use, environmental quality, and citizens' well-being. Options included hydrogen generation, CO2 extraction, electric boilers, heat pumps, geothermal and solar energy, and network upgrades. PLEXOS software was used to plan construction until 2030, aiming to guide investment decisions and project development.
