Sentinel for Asset Management

Whether you operate a single plant or a large fleet, the ability to manage the data flows required to plan, trade and despatch the energy you produce effectively are business critical.

Our asset management suite encompasses both trading and control point operations, including National Grid certified EDT and EDL applications. The status of all generating units is brought together through our Position Monitoring tools, available as both stand alone and EDL integrated options. Operational Shift Log (OSL) completes the picture, streamlining event logging and reporting across your entire asset register.



Communicating to National Grid an accurate picture of expected future generation and Bid Offer pricing is both obligatory - and, in the case of commercially priced Bid Offer data - fundamental to the profitable operation of your generating assets. With customised features specially developed for wind, gas and nuclear generation, Sentinel EDT delivers all the tools you need to operate your trading point submissions effectively. A vital component of your BETTA market system.

Sentinel EDT is National Grid certified and offers a range of features designed to ensure that submissions are made securely and consistently.

PN, BOD and MEL submissions can be driven by either imports or manual entries. In both cases all entries are validated for compliance before submission. As a result, Sentinel EDT guards against submission issues and inaccurate declarations, helping to minimise imbalance charges. This feature is enhanced by the facility to configure the sensitivity of the parameters that govern submissions so they become tighter as the time interval between submission and delivery shortens.

For greater flexibility, Sentinel EDT can be deployed as part of a wider Sentinel solution or through integration to a third party system. When working alongside other Sentinel products, EDT submissions can be viewed in a single display with EDL data, by both station operators and traders, using the Position Monitoring module.

Non-instructable Generating Units

EDT can automatically differentiate between generating units that can be instructed by National Grid and those that are not part of the balancing mechanism, routing values to the appropriate destinations when the generation plan for the entire portfolio is prepared and submitted. This ensures that all required National Grid submissions are made, while data relating to non-instructable units is delivered to station operators.

Integrating Wind Power Forecasts

Changes to wind speed and direction have a major impact on turbine and wind farm performance. However, not all changes are relevant in terms of submission to National Grid. Sentinel EDT can automate the assessment of wind forecasts, recognising when conditions require new submissions. The result is that both the magnitude and timing of changes are accounted for before any submission is made.

Automated Alerts

Exceptional events, like submission failures, can be commercially costly. Sometimes events don’t follow a plan so Sentinel Alerts highlights exceptional events and conditions, routing information to those best placed to respond. Delivery via the Sentinel desktop, email and SMS ensures that nothing is missed and issues are addressed promptly and effectively.

Key Features >

  • Fully certified interface for submission of PN, MEL and BOD to National Grid
  • Automatic flow of information between EDT, EDL and Position Monitoring applications at the generation asset control centre and the trading location gives the whole organisation a clear picture of the generation plan
  • Manual, semi-automated or fully automated data entry / import functions
  • Selective submissions based on accepted position in accordance with National Grid's Submitter Guidance
  • All data validated prior to submission
  • Integration with despatch planning and power availability forecasts streamlines EDT data submission
  • Automated exception condition monitoring and alerting.


Sentinel EDL (Electronic Dispatch Logging) handles the two-way traffic between your control point and National Grid associated with the processing of BOA instructions and the re-declaration of key values signalling changes to generating capacity such as MEL.

Certified with the system operator, National Grid, Sentinel EDL delivers a range of features designed to streamline the processing of BOAI and resubmissions of key values including MEL and SEL. Offering both automated and manual modes, Sentinel EDL can be configured to reflect your requirements. And, through the application of custom features designed specifically to enhance the operation of gas, wind and nuclear generation, it delivers a solution aligned precisely to your needs.

Sentinel EDL enables you to differentiate between generating units that are part of the balancing mechanism and those that are not, automatically routing the required values and submissions to the appropriate parties. Should exceptional conditions occur, preventing automated processes from executing, integration with Sentinel Alerts ensures that all interested parties are notified promptly to enable remedial action.

Key Features >

  • Control point management that handles instructions (e.g. BOA, Ancillary Services) from and submissions (e.g. MEL, SEL) to National Grid
  • Use in combination with fully configurable alerts module
  • Transfer responsibility for individual generation units between operators
  • Automated data transfer to other Sentinel modules to maintain data integrity
  • Automatic and manual instruction acceptance operational modes.

Position Monitoring

Sentinel PM 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 EMC and station versions of the client, it enables you to configure custom views for traders and operators.

Sentinel PM is capable of displaying any data stored in the Sentinel database, not just those items necessary for operation in the BM such as PN, MEL and BOA data.  To complement this flexibility, any Sentinel PM client can be configured to create custom views of data of interest to different parties. For instance electricity traders can view aggregated information for target v actual generation across the generation portfolio in addition  to unit-specific views, whilst gas traders can view their forecast, actual and nominated gas usage on a single screen. Control room operators can also have their own customised views of the data of interest to them, with the Sentinel infrastructure synchronising the data values shown on each client application in real time so that everyone has the same, clear, picture of the generation assets’ performance.

Meter data integrity and system resilience are built in through the facility to utilise dual plant data sources with automatic fail over. Vital information is displayed clearly in tabular and graphical formats and includes current spot values and settlement period totals and averages, creating a high level of visibility of the status of each generation asset and the portfolio as a whole.

Configurable alerts ensure that exceptions are flagged to operators and traders via email and SMS so that time sensitive issues are addressed. These actions can streamline station operations and create opportunity to trade out or correct impending imbalances. Available as a stand alone product, or integrated with EDL, Sentinel PM is flexible and adaptable to your needs creating a clear focus on important events and delivering the visibility required to operate your plant effectively and profitably.

Operational Shift Log (OSL)

Supporting both automated and manual event tracking, accommodating planned and ad-hoc events, OSL delivers comprehensive event logging and reporting tools within a web framework that gives you total control over the configuration of your asset register and streamlines key business processes.

Accurate logging and tracking of operational events and their impact on performance is a vital task that delivers many benefits. Operational efficiency is enhanced due to the streamlined transfer of information between shift teams and between operators and commercial users. Future performance can be improved through the opportunity created to analyse historical events, learn from them and develop business processes accordingly. And, critically, the maintenance of detailed, reliable health and safety records provides a vital reference point in the event of an incident and can ensure compliance with applicable legislation.

OSL delivers a suite of tools that enables the logging and management of events as they happen. Through a highly configurable user interface, events can be entered and updated using a combination of pre-defined values and free text commentary, improving the quality and structure of the information captured for each event.

Using a web framework, OSL is accessible throughout the organisation ensuring a shared view of all events with scope for personalisation of the information provided at user level.

Multiple Logs

OSL supports the creation and management of multiple log books. These can be aligned to the needs of individual roles or made available to multiple parties enabling collaboration across the organisation. Common applications for OSL include Shift Engineers Log, Unit Operators Log, Maintenance Activity Log and Project Logs.

Event Tracking

All events added to OSL are associated with specific assets, utilising an established equipment coding structure or any other user defined asset hierarchy. Events can be added to the log automatically or manually. Automated logging is highly effective as a means of releasing operator resources from the task of logging routine events such as plant state changes. This is achieved through the capture and application of changes to both analogue meter values and digital tags by OSL.

Manual event logging and tracking utilises a combination of pre-configured fields and free text entries to achieve high levels of data quality and consistency while accommodating the addition of supplementary comments to events. Further content can be added in the form of attachments including digital images and document files to provide context and improve understanding.

Once entered an event can be copied between logs to create a shared view of a single instance of it, avoiding the risk of multiple, inconsistent versions. Recurring manual events can be duplicated within a log for improved efficiency and consistency.


OSL is intrinsically flexible, creating many options for integration with third party systems, enabling you to capture relevant information from your other business systems, creating a consolidated view of events in a single location.


OSL offers a range of predefined report formats and utilises Sequel Server Reporting Services to extend the range of user defined reporting options available.


Application security is highly configurable ensuring that permissions determining read, write and no-access rights are controlled at component level for each role or user.
