NGI Overview
NGI helps you enter nominations, change nominations, view scheduled quantities, check inventory levels and other storage transactions.
NGI is Internet-based, meaning that it is not "loaded" onto you computer. To access the program, all you need is a standard Internet browser, such as Google Chrome, Mozilla Firefox or Microsoft Internet Explorer (see "System Requirements" for a list of the correct versions of these browsers).
And since NGI is Internet-based, it can be accessed from any computer with an Internet connection. You can access NGI from your computer at work, from your laptop, from your mobile device, or your computer at home.

About Nominations
Nominations on NGI are entered using a "Pathed" model, in other words, by specifying a Storage Contract, a Transaction Type, Beginning and Ending Dates/Times, Injection/Receipt information (quantity, upstream shippers, etc.) or Withdrawal/Delivery information (quantity, downstream shipper, etc.).
Once a nomination is entered, it is available for viewing and editing in NGI any time prior to flow.
For multi-day nominations (say, for example, a nomination for an entire month), NGI takes the nomination information and breaks it into daily "buckets". Each day of the nomination can then be edited without effecting the rest of the month's nominations.
For example, prior to flow, a Storage Customer enters a nomination for 10,000 Dth per day beginning on Day 1 at 9:00am and continuing through Day 20 at 9:00am. NGI takes that information and creates 19 daily buckets. If the Shipper then decides on the 7th to change the flow on the 9th to 11,000 Dth, the Storage Customer edits the nomination for Day 9, changing the volume to 11,000. The volumes on the 8th and the 10th remain at the original rate of 10,000.

About Inventories and Fuel
Storage inventories are based on daily Scheduled Quantities and the contract fuel percentage. Specifically, NGI updates Customer inventories each night, using that day's scheduled quantities to update each contract inventory as follows:
New Customer Inventory = Previous Customer Inventory + Scheduled Quantity - Fuel Quantity.
Fuel is applied by NGI in the following manner:
- For injections, the Injection Fuel Rate provided for a given contract is applied to the scheduled quantity to produce the Fuel Quantity. The Fuel Quantity is subtracted from the scheduled quantity and the result is added to the contract inventory.
- For withdrawals, the Withdrawal Fuel Rate provided for a given contract is applied to the scheduled quantity to produce the Fuel Quantity. The Fuel Quantity and the scheduled quantity are then subtracted from the contract inventory.
NGI uses the following sign conventions:
- Positive numbers represent injections, or flows coming into the storage facility.
- '-' or negative numbers represent withdrawals, or flows leaving the storage facility.

Why won't my screen update after I enter information?
You are probably experiencing an Internet problem known as "caching." A cache is a locally stored piece of Internet data. Once you fetch data from an Internet server (like NGI), your computer (or your company's Internet gateway computer) stores the data so that it is quickly available next time you request it.
The problem with this "time saving" feature is that you don't always receive the newest data from the NGI server - you get the locally "cached" version.
To solve this problem, try the following:
- Use the "Reload" button on your browser to retrieve non-cached data.
- "Log-out" or close your browser between NGI sessions.
- Ask your system administrator about the caching policies in your company. They may be able to increase the cache "refresh" interval or minimize caching effects.

Why is the system slow?
The response time provided by NGI depends on numerous factors. NGI is designed with minimal download time in mind, but because it is Internet-based, many communications systems are involved in bringing NGI to your computer.
To help solve this problem, examine:
- Your Internet connection - NGI requires at least a broadband connection for satisfactory response. Slower connections, as typically found in hotels or through retail Internet service providers, may produce longer waiting times.
- Your computer - Running multiple applications at the same time will slow any computer. Try reducing the number of applications active while using NGI. Also, make sure your computer meets the minimum requirements for NGI (see "System Requirements").
If the problem persists, contact your Storage Operator.
