SENTINEL FOR COMMERCIAL OPERATIONS

Effective capacity forecasting and dispatch planning are vital inputs to effective trading.

Sentinel delivers the tools you need to model the behaviour of different types of generating assets, based on the fuel they use and the external factors that influence their operation.

By modelling technical availability, dispatch plans and fuel forecasts, Sentinel provides high quality data to enhance the accuracy of EDT submissions to National Grid, leading to improved dispatch performance and revenue generation.

The Sentinel Elexon interface takes care of EVCN and MVRN notifications ensuring an accurate traded position is always available for settlement.

  • Ready for EBS launch
  • Powerful forecasting and planning tools

Core tasks supported by Sentinel

There are a nmuber of activities that must be carried out to ensure compliance with the BSC when participating in the BM. Sentinel has them covered, and a lot more besides.

 

Elexon Contract Notification

The Sentinel Elexon Interface module is an Elexon-certified application that enables Market Participants to exchange information with Elexon securely and reliably, for both contract notification and settlement.

Bid Offer Pricing

Market Participants are required to provide Bid and Offer prices for each BMU for each half-hour settlement period, indicating the prices that at which they are willing to increase or decrease their output, relative to their FPN (Final Physical Notification), to defined levels of output if instructed to do so by National Grid to via BOAs. Prices are submitted in the form of "ladders"; pairs of Bid and Offer prices for each of up to five MW levels between FPN and MEL, on the case of Offers, and FPN and zero in the case of Bids. Sentinel EDT provides features designed to streamline the setup and submission of these values to ensure that the capabilities of BMUs are priced and notified efficiently. 

Physical Notifications

In addition to providing values for planned MW levels (PN) and maximum MW levels (MEL) for each half-hour settlement period, Market Participants must also provide sets of dynamic values such as NDZ, MZT, MNZT and ramp rate, for each BMU defining the capabilities of the unit in terms of its ability to repsond to instructions (BOAs) from National Grid, and the degree of flexibility it can offer in terms of varying its level of output rapidly. Sentinel EDT enables you to make comprehensive physical notifications, with many labour saving tools designed to ensure that National Grid is notified of changes to planned operating conditions as soon as possible.

Monitoring BMU Performance

Sentinel PM (Position Monitoring) can display any data stored in the Sentinel database alongside actual plant data from either a Kenda summator or an OPC compliant plant historian or SCADA system. Through separate versions of the client, it enables you to configure custom views for traders and operators. Combining spot values, tables and charts, Sentinel PM delivers instantaneous information about the status of each BMU or your portfolio as a whole, enabling you to identify issues and take action to mitigate the commercial impact of trips, imbalances and other unforeseen events.

Availability Forecasting

A sound forecast of the output available from a BMU at various times in the future is a valuable input to the Physical Notification process for units reliant on a range of energy sources, both fossil and renewable that are affected by external conditions including temperature, humidity and wind speed and direction. In addition to accounting for external factors that impact on output, other events such as planned outages and constraints must also be factored into the forecasting process. Sentinel TA (Technical Availability) enables you to capture the details of weather forecasts and outage plans, incorporating them into bespoke models reflecting the characteristics of your BMUs to produce forecasts for use in your planning and notification processes.

Dispatch Planning

The production of a dispatch plan for generation units that is technically feasible, contractually valid (if there is a PPA in place) and commercially profitable is a difficult problem to solve and one that is addressed by Sentinel DP. The Sentinel DP module uses the modelling capabilities of our Model Editor to produce customised and configurable models which reflect technical parameters such as the necessary notice to deviate from zero (NDZ) load and ramp rates; contractual obligations from a PPA; and other commercial terms, to produce a generation plan that forms the basis of data submitted to National Grid and to the control centre for your generation assets. It can also be sent automatically to other interested counterparties such as offtakers.

Gas Demand Forecasting

Forecasting and notifying gas usage to various parties over multiple time frames is a requirement common to all gas fired power stations. The Sentinel GD module uses the modelling capabilities of our Model Editor to produce customised models that calculate and nominate forecast and actual gas usage to third parties according to your plant’s technical parameters and the terms of your gas supply contracts.

Productivity Gains through Automation

As the energy transition gathers pace, the management of an increasingly complex and distributed power generation and demand management fleet will demand changes in the processes that underpin it.

By introducing automation options into routine tasks, based on configurable operating parameters, we will continue to streamline the way assets are managed to help you control costs and enhance profitability.
