Review pipeline storage manager¶
The Pipeline Storage Manager screen is used to monitor, manage, and analyze storage contract activity across pipelines over a selected date range. It provides a consolidated operational view of storage balances, injections, withdrawals, BAV impacts, violations, and valuation data, enabling users to track storage performance against contractual and operational limits.
This screen plays a critical role in daily storage operations, helping bridge scheduled storage activity with actual operational outcomes, and supporting downstream processes such as valuation, compliance monitoring, and reporting.
The primary purpose of the Pipeline Storage Manager screen is to:
- Load and review active storage contracts for a pipeline.
- Analyze daily injection and withdrawal activity.
- Track cumulative storage balances and net changes.
- Identify storage rule violations and BAV impacts.
- Support storage valuation, AMA, and capacity release analysis.
Prerequisites¶
Before using the Pipeline Storage Manager screen, ensure the following prerequisites are met:
- The user has the add or modify permissions for the Pipeline Storage Manager screen.
- Pipelines and storage contracts are configured in the system.
- Storage contracts are active for the selected date range.
- Storage rules, limits, and BAV types are defined where applicable.
- Daily nomination or deal data exists for storage injection or withdrawal activity.
Procedure to review pipeline storage activity¶
Step 1: Navigate to the Pipeline Storage Manager screen¶
- Log in to the nGenue application.
- Click the Search icon and enter Pipeline storage manager.
- Double-click Pipeline Storage Manager to open the Pipeline Storage Manager (Pipeline Operations) screen.
- The screen is divided into three main sections:
- Storage Query: Used to filter and load storage contracts.
- Storage Contracts: Displays storage contracts matching the query.
- Storage History and Valuation: Provides detailed operational and valuation views.
Step 2: Define Storage Query criteria¶
The Storage Query section allows users to filter and load storage contracts based on pipeline and date range.
| Fields | Description |
|---|---|
| Pipeline (Required) | Specifies the pipeline for which storage contracts are to be reviewed. This is a mandatory field. |
| Pipeline Location | Filters storage contracts by pipeline location, if applicable. |
| Date Range From | Defines the start date for reviewing storage activity. |
| Date Range To | Defines the end date for reviewing storage activity. |
Click Load Storage Contracts to load storage contracts that match the selected criteria.
Step 3: Review Storage Contracts¶
After clicking Load Storage Contracts, storage contracts are displayed in the Storage Contracts grid.
This grid provides a high-level view of available storage contracts for the selected pipeline and date range.
| Columns | Description |
|---|---|
| Contract ID | Internal system identifier for the storage contract. |
| Pipe | Pipeline associated with the storage contract. |
| Contract Name | Name of the storage contract. |
| Location Name | Storage facility or location associated with the contract. |
| Contract Number | Contract reference number. |
| Description | Additional descriptive details for the storage contract. |
Selecting a storage contract loads detailed activity in the Storage History and Valuation section.
Step 4: Review Storage History and Valuation¶
The Storage History and Valuation section provides detailed operational and analytical views of storage activity. This section is organized into multiple tabs, allowing users to focus on specific aspects of storage behavior.
Daily Inj/Wtd History tab¶
This tab displays daily storage activity, including injections, withdrawals, and balances.
| Fields | Description |
|---|---|
| Date | Gas day for the storage activity. |
| Pipeline | Pipeline associated with the storage contract. |
| Contract | Storage contract name. |
| Location | Storage facility location. |
| Net Change | Net daily change in storage volume. |
| Cumulative | Running storage balance as of the selected date. |
| Is BAV | Indicates whether Best Available Volume logic is applied. |
| Max Storage | Maximum storage capacity allowed. |
| Min Storage | Minimum storage level allowed. |
| Max Inj Qty | Maximum allowable injection quantity. |
| Max WTD Qty | Maximum allowable withdrawal quantity. |
Monthly Valuations tab¶
This tab provides a summarized valuation view of storage positions over time.
| Fields | Description |
|---|---|
| Val/MM | Valuation per unit volume. |
| Valuation | Total monetary value of stored gas. |
| Previous Actual COG | Prior cost of gas used for valuation comparison. |
Storage Balance Strategy and Targets tab¶
This tab helps users analyze storage behavior against strategic targets.
- Displays planned versus actual balances.
- Supports operational planning and compliance monitoring.
- Highlights deviations from target storage levels.
AMA and Capacity Release tab¶
This tab displays information related to Asset Management Agreements (AMA) and capacity release activity.
- Tracks capacity released to third parties.
- Supports reconciliation of released volumes against storage balances.
- Helps ensure compliance with contractual and regulatory requirements.
Storage Balancing Rules tab¶
This tab displays storage balancing rules configured for the contract.
- Identifies rule thresholds.
- Highlights violations when operational activity exceeds defined limits.
- Supports proactive issue identification.
Step 5: Apply filters and refresh history¶
Within the Storage History and Valuation section, users can further refine the view using:
| Options | Description |
|---|---|
| Date Range | Restricts the displayed storage activity to a specific period. |
| BAV Type(s) | Filters data based on selected BAV types. |
| BAV Only | Displays only records where BAV is applied. |
| Show Violations Only | Displays only records that violate storage rules. |
Click Refresh Daily History to reload data based on selected filters.
Results section explanation¶
After reviewing storage activity:
- Storage balances reflect finalized operational volumes.
- Valuation data is available for financial reporting.
- Rule violations are visible for compliance review.
- Data can be used for downstream processes such as:
- Storage valuation
- Risk analysis
- Regulatory reporting
- Operational planning
Key points¶
- Pipeline is a mandatory field in the Storage Query section.
- Storage contracts must be active for the selected date range.
- Daily storage activity drives cumulative balances and valuation.
- BAV logic directly impacts storage balances and compliance.
- Use Show Violations Only to quickly identify operational risks.
Summary¶
The Pipeline Storage Manager screen provides a centralized, operational view of pipeline storage activity. By combining storage contracts, daily operational history, valuation metrics, and balancing rules, it enables users to effectively monitor storage performance, manage compliance, and support financial and operational decision-making.
