What this means for SmartestEnergy

Following initial investment in 2001 – SmartestEnergy has expanded it's UK market share from renewable generation PPAs to industrial and commercial retail supply, into asset optimization and then to the small business supply market through acquisition of a long term partner.

In 2019, SmartestEnergy opened its first international office in Syracuse, NY and shortly after established a presence in Australia.

Throughout the past 20 years Marubeni's backing has meant being able to focus on growing, innovating and investing for the future - taking energy market volatility in our stride and providing certainty for our partners and customers. It gives us the balance sheet to manage our own wholesale trading, avoiding expensive credit sleeves and allows us to grow.

With the backing of Marubeni and the wider SmartestEnergy Group, we are a financially sound, credit worthy partner today, and for the future. Having our own trading desk provides our customers access to the wholesale market without expensive credit sleeves and enables us to offer transparency and informed opinion. And a low cost of capital enables us to continue to invest in our technology, our business and therefore, in yours.
