NSW Premier Gladys Berejiklian announced on Wednesday that the state would cut emissions by 50 per cent below 2005 levels by 2030, up from the previous 35 per cent.

"Our Net Zero Plan is expected to attract more than $37 billion in private sector investment into NSW, support more than 9000 jobs [and] save households about $130 on their electricity bills," she said.

Dr McGirr, who has previously spoken in favour of action on climate change, said he was "very pleased" with the announcement.

"For people in our region, there are good opportunities for this, particularly in Bomen with the circular economy and waste-to-energy proposals and certainly with the hydrogen, that's all very exciting," he said.

"However, we are still dealing with the impact of solar farms and transmission lines on communities and we need to get that right ... it has a real impact on people affected by them."

Deputy Premier John Barilaro said regional communities would see "more jobs and more investment" the new industries set to emerge over the coming decades.

"Whether it is in modern manufacturing, minerals or agriculture, regional NSW is home to the skills, infrastructure and resources needed as the demand for low emissions technologies like batteries and hydrogen grows," he said.

Wagga mayor Greg Conkey said Wagga was in an "ideal position" to benefit from increased demand for renewable energy and hydrogen at the Bomen special activation precinct.

"We have got some large solar plants already in the city, and that's good news but they do pose some issues such as glare and potential contamination," he said.

"We are fully aware of those issues but we are ideally located to capitalise on the positive aspects."

Greens Wagga City Council election candidate Jenny McKinnon said she had "absolute support in principle for concrete steps towards a zero emissions target".

NSW Farmers vice-president Xavier Martin welcomed moves to lower power prices but said protection of prime agricultural land had to be a fundamental part.

"We remain concerned about regional renewable energy zones - there is clearly scope for this sort of infrastructure, but we must ensure it does not displace food and fibre from quality land," Mr Martin said.

The NSW government intends to declare a new renewable energy zone in south-west NSW but has yet to confirm its exact location.
