A request has been made to prevent one of Wales' "great treasures" from being destroyed by 60 miles (96 km) of pylons spanning the countryside.
Bute Energy wants to link the energy grid close to Carmarthen with a proposed wind farm in Nant Mithil, Powys, across the Towy Valley.
Plaid Cymru leader Adam Price urged reconsideration at a public gathering that attracted over 250 attendees at the Llandovery Rugby Club.
The plan, according to the company, could generate enough energy for 200,000 homes.
"Power Wales with clean, green energy," it continued, "and strengthen local communities through investment, employment, and skill development.".
One of Wales' "great treasures" needs to be protected, Mr. Price said at the meeting on Friday.
The plan, according to Mr. Price, who represents the area in the Senedd (MS), would "trash a vital part of inheritance," he said. "We support the aim of ensuring Wales meets the target of 100% renewable electricity generated in Wales, but we don't have to do that by building the cheapest option that will be incredibly environmentally damaging in this area of great sensitivity," he added. ".
He demanded that the business review its plans and take into account underground infrastructure.
The Welsh government wants Wales to reach a net zero goal by 2050, which means that all energy will come from green or renewable sources.
Bute Energy claimed that its wind farm could generate over 200 MW of clean energy, which would be sufficient to power 200,000 homes in Wales.
According to spokesman Aled Rowlands, it will be disclosing more information about its plans over the coming weeks and soliciting feedback from the general public.
He continued by saying that since most people were aware of the value of renewable energy sources and the necessary grid infrastructure, a net zero goal could be achieved.
The business, according to Mr. Rowlands, is based in Wales and is "developing a unique solution" for the nation. He continued, "We are currently engaging with landowners to help us develop a detailed and accurate assessment of potential routes.
"Land is not automatically included in a route or have infrastructure built on it just because it has been surveyed. In addition, we will work with landowners to determine the scope of work and timing before conducting any surveys. ".
An online petition asking for the burying of the electricity cables has more than 1,000 signatures as of right now.
