Addressing Black representation in the energy industry
At Octopus Energy, our mission is to drive the global renewable revolution and make green energy affordable for all. In order to succeed, we need to build a team that represents everyone in our society. Unfortunately, Black professionals make up < 2% of the energy workforce, which is a significant under-representation compared to the ethnic composition of the UK. To help address this, we have created an internship programme that is only open to candidates who identify with any Black, Black British, African or Caribbean background. We are committed to promoting equality, and this internship is an important step in our effort to foster greater diversity and inclusiveness in our business and industry.
Applications for all our internships will close on the 17th April. Please do not upload a CV when asked for 'Resume/CV'.... instead, upload a cover letter made up of no more than 500 words (instructions below) 💚
This is our sixth year running the internship programme. You can hear from our past interns and learn about our previous internships.
Who we are
We are an international energy supply company who put customers at the heart of everything we do. We empower our people to give outrageously good customer service, and fight to make energy fairer, more affordable, and more accessible for all. We are striving to halt the climate emergency by unlocking a smart, 100% green grid. We are using technology to transform the energy system; making electricity green and affordable, creating one-of-a-kind energy innovations.
Our work is powered by freedom, autonomy and responsibility. We won best company to work for in 2022 and were voted as one of the 50 best places to work in 2022 on Glassdoor. Our Group CEO, Greg, has recorded a podcast about our culture and how we empower our people - give it a listen to find out more about Octopus Energy!
About the role
To achieve Net Zero emissions, greater grid flexibility is essential to cope with a growing range of low carbon technologies making up the power sector as well as enable the decarbonisation of heating and transport.
Octopus Energy is at the forefront of the energy transition and developing innovation to meet the grand system challenges of decarbonisation. You will be a key member of the team that develops transformational solutions and rapidly implements these to meet the urgent and global need for energy flexibility. Here is an example of the transformative work our team has been able to undertake.
We are looking for a Flexibility Intern to join our fast growing team in order to provide robust quantitative and qualitative assessments which underpin our flexibility strategy. As part of this, you will be doing research into our customer base and provide the team with insights on consumer behaviour.
