English to Arabic Other Energy / Power Generation translation of utility document

Dear colleagues:

Greetings!

What is the best translation of this phrase into Arabic in this context. And how we would translate the whole phrase (Core Gas Aggregation Services). Please I am looking for a creative translation. I do not think that literal translation would work here. If there is an explanatory translation that conveys the meaning of the original phrase into Arabic, that would be great!

Please provide references and/or explanation.

Thank you for your help!

Core Gas Aggregation Services

You may choose to purchase natural gas for your home from a third-party gas service provider instead of your regular utility company. These companies are called Core Transport Agents (CTAs).

CTAs have been approved to sell natural gas to consumers, and you may decide if you want to buy gas from these companies or stay with your regular utility company.

Beware of companies who come to your door and tell you that you are required to change companies. They may say “We are your new gas company” or “Your street is being switched to our company”. CTAs need your permission before they change your service.
