As head of comms Towers will be responsible for media, corporate, financial PR, brand and public affairs. She will also provide strategic advice to founder and CEO Juliet Davenport.
The AIM-listed company sees itself as a challenger brand to the larger suppliers, and generates and supplies energy from renewable sources including wind, solar and tidal.
"Good Energy has seen strong growth in 2013, with a 32 per cent increase in customer numbers, because of distrust in the Big Six suppliers," said Towers.
She said the strategy for the next two years was to grow Good Energy’s core electricity, gas and feed-in-tariff site customer bases, and that the company was aiming to grow the renewable generation capacity it owns and operates to support 50 per cent of purchased power by 2016.
Comms strategy will involve increasing brand awareness, attracting new consumers and business customers and influencing the policy arena in the run-up to the next election, she added.
Towers will head up a team of five including a public affairs manager, comms manager, two press officers and a comms assistant.
Her predecessor was Edward Gill, who was head of external affairs before moving to FTI Consulting at the end of 2013 as a senior director in the energy and environment team.
The role was vacant for a period while the comms operation was restructured and Towers recruited for the new role of head of comms. During this time the company was advised by strategic communications consultant Lauren Branston, former Coca Cola European corporate comms director.
Towers will also be working with the marketing team on partnerships with organisations such as the National Trust and the Soil Association.
Towers was chief press officer at DECC, covering its energy policy portfolio and leading on EMR, investment, shale gas, renewables, gas, coal and oil. She also advised secretary of state Ed Davey and the other energy ministers.
She was previously head of comms at the Joint Committee on Climate Change.
