LIVE INFORMATION
ENERGY AND ESS
The Energy and Essential System Services (ESS) submission post-box is the heart and focal point of the Horus WEM trading system. This rich event-driven user interface is where the Trader spends most of their time interacting with the market, submitting re-bids to AEMO and monitoring live market prices, facility schedules, bid statuses and other market related information. The post-box is dual purpose, in that it presents live information and allows interactive editing, validation and posting of submissions.

TRADING CONVENIENCE
CO-OPTIMISE TRADEABLE SERVICES
All Energy and ESS tradable services are conveniently located side-by-side within the interface, allowing the Trader to conveniently select their desired combination of one or more tradeable services to view and allowing for more efficient co-optimisation and cross-validation.
Powerful ESS Trapezium logic has been introduced to automatically re-evaluate and adjust Enablement and Break Point levels in response to changes in Energy Maximum Injection Capacity, ESS Maximum Availability and Trapezium Angles.

CONFIGURABLE
PORTFOLIO TRADING
The Horus WEM Trading System makes trading a small or large portfolio of tradable facilities a breeze. Horus provides users with the ability to create and configure company specific “portfolio groups” to logically group assets (e.g. by technology or fuel type) for ease of trading and viewing of positions in providing group-specific dashboards. Individual facilities are set out on separate selectable tabs within the interface, allowing users to navigate between them seamlessly.

TRADE BY EXCEPTION
TRADING PROFILES
Profiles are an innovative and powerful feature contained within the Horus WEM Trading System which allow Traders to construct and apply pre-determined Energy and ESS bids for repeatable situations. Profiles allow the Trader to “trade by exception”, reducing manual data entry within the post-box and potential oversights leading to operational or compliance issues.

OUTAGES

VISIBILTY
CONSTRAINTS
Constraint information is made available to Traders in the Horus WEM Trading System, including graphical information on binding and near-binding constraints on a per interval basis. This provides Traders with quick visibility on constraints that may pose actual or potential impacts to their facility’s operating profile, with information derived directly from AEMO’s WEM Dispatch Engine (WEMDE) every 5-minutesQ

GREATER VISIBILITY AND CONTROL
AUTO-BIDDING GATEWAY
The Horus WEM Trading System provides clients with greater visibility and control of assets that are utilising auto-bidding software. By using Horus as a submission gateway to the market, clients have full control over when auto-submissions are “passed straight through” to the market, and when auto-submissions are turned off to allow manual intervention from Traders. The Horus WEM Trading System also centralises submission history, providing a single source of truth for compliance purposes.
