Introduction

To send nominations to Transco you must use the Gemini API. EuroRunner sends notices to Gemini synchronously; confirmations (scheduled amounts) are fetched asynchronously.

Set-Up

Configuration

This section assumes that you already have the following set-up in EuroRunner:

Item	Type	Name in EuroRunner	Comment
Transco	Network	NTS
NBP	Point	NBP
NBP	Flange	NBP	Usually Balancing Flange

To set-up EuroRunner to allow sending of notices using Gemini; set the following properties for the NTS network:

1. This option enables sending of notices.
2. Choose the interface with which EuroRunner will interact: Gemini
3. List of formats in which to send the notice, for Gemini this is always XML
4. Provides an alternative easy to read view of the notice data.
5. Tick Include Entry ID/Exit ID and enter your full Gemini Entry and Exit Service IDs

Also set the flange properties for all flanges in the NTS network you wish to send notices to Gemini for:

1. Ensure this is unticked as Gemini requires entry/exit to be kept separate.
2. You must enable trading at the NBP, you may also wish to allow trading at other flanges.
3. You must select this option for the NBP, but not for any other flanges.
4. Checking this allows daily notices to be sent.
5. Select the Default template to send notices with.
6. Provides an alternative easy to read view of the notice data.

To set-up trading of gas internally in the NTS network, i.e. trading with other NTS shippers; set the following properties for each shipper to trade with using the Flange Shippers tab of the NTS network properties:

1. Your Gemini Activity numbers for entry (buy) from other shippers
2. Your Gemini Activity numbers for exit (sale) to other shippers

Similarly to set-up trading of gas externally to the NTS network, i.e. trading with an Interconnector shipper (even if this is yourself); set the same properties for each shipper to trade with using the Flange Shippers tab of the Non-NTS network properties.

To enable access to Gemini the following details must be set-up on the Gemini tab of the Security screen:

1. The name of the Me counterparty in EuroRunner
2. Licence key for the GMSL Gemini component
3. Username required to access Gemini
4. Password required to access Gemini for this username
5. You must click Apply to save the changes

These values are stored in the registry, see the Gemini section of the Registry documentation)

You can enable and disable polling of Gemini for confirmations using the Services tab of the System Options screen:

Note: This option is available for administrators only.

Technical

The EuroRunnerGeminiQC COM+ Application, controls outgoing and incoming Gemini notices.

Notices are sent synchronously using the GeminiSenderQC component.

Gemini is polled for confirmations asynchronously using the GeminiPollerQC component, if the process fails all attempts, then the exception handler is called in the GeminiPollerEX component, this retries one final time, and if it fails again an error is logged.

EuroRunner connects to the Gemini API using https to set and get nominations.

Configuration

To enable Gemini you inform EuroRunner that you intend to send notices to Gemini during the EuroRunner server installation. If you did not select this option during installation you can still set up sending of notice to Gemini using the user interface (see Set-Up section), but you can only set-up the polling of Gemini for confirmations manually by creating the required registry keys (see the Gemini section of the Registry documentation) and then restarting the GMSL Service.
