His spokesperson stated that Boris Johnson does not plan to introduce a windfall income tax on profits from electricity firms before he leaves office as prime minister.
To help families with rising costs, the government announced in May that oil companies and other petroleum-related businesses would be subject to an additional 25% tax over the next twelve months.
However, the spokesperson for PM said that such a policy would not be extended to electricity producers.
After the announcement, shares in Centrica and SSE increased by 3%.
In a bid for around PS5bn, the government introduced a new tax to energy companies in May. It is known as the Energy Profits Levy.
This happened after BP, Shell and other oil companies reported huge profit increases. These increases were due to increased demand and supply concerns following the invasion of Ukraine by Russia, a major exporter and importer of fossil fuels.
The windfall tax, a tax that is imposed on a company by a government, on UK oil and natural gas producers could be used to assist households with rising energy costs.
When asked Monday if the windfall tax would apply to electricity generators too, the prime minister's spokesperson said that they would not be seeking to adopt any new policies or major fiscal changes.
"So, there are no plans to do that."
A spokesperson for the government stated that they would continue to assess the size of the profits and take appropriate steps, but that there were no plans to extend or introduce that to this group.
The BBC reached out to the Treasury for comment.
Labour called for the government to "backdate" its Energy Profits Levy from January in order to increase "extra tax revenue" from oil- and gas companies.
James Murray, Shadow Treasury minister, claimed that including the extra months could generate an additional PS1.9bn. It urged the government "to remove VAT on domestic electricity bills for the remainder of the year".
According to the latest forecasts domestic energy bills could rise to more than PS3,300 per year in winter according to the latest forecasts. This follows an increase of PS700 annually in April.
Next week, a set of payments from the government to assist with bills will be made. According to the government, all UK households will be eligible for a PS400 discount on fuel bills. People on benefits will also receive an additional PS650.
Labour's Mr Murray stated that a total amount of PS200m would be used to help people with multiple properties. The energy support package for households was "cobbled together" at last minute.
"That's not fair. He added, "That is not a good usage of public money."
Financial Times first reported the possibility of a windfall tax on electricity generators. This includes renewable energy operators.
As they considered how to tax such producers, sources close to the Treasury pointed out that both renewable and nuclear energy generators also made huge profits due to rising electricity prices. Because they don't depend on expensive gas for power production, they also enjoy extra profits.
However, energy companies warned that a proposal to increase a windfall tax on renewable energy could undermine investor confidence before key auctions for licenses to develop new solar and wind projects.
One of the UK's largest investors in renewable energy claimed that his profits from renewable energy were in the hundreds of millions. This is in contrast to the PS7bn Shell made and the PS5bn BP made in the first three months in 2021.
