Recognising and celebrating the very best in energy storage

Recognising and celebrating the very best in Energy Storage

The Energy Storage Investment Awards – brought to you by the publishers of Energy Storage Report – recognises and celebrates outstanding achievements in energy storage development, investment and finance in the renewable sector.

This awards programme is the benchmark for excellence, raising the profile of winners and contributing to the overall growth and reputation of the energy storage industry.

The gala is a spectacular showcase of achievement, uniting key players, influencers, and decision-makers for an evening of recognition, networking and knowledge exchange.

Join us for an unforgettable evening where we showcase pioneering storage investors and lenders, outstanding storage developers, ground-breaking project finance and M&A deals, and the rising stars driving progress in the energy storage sector.

Five reasons to enter

01

Awards help you build the credibility of your business

Winning an award, and even appearing on an awards shortlist, will encourage prospective clients to take you seriously even before they dig deeper into your company’s background.

02

Awards give your business an edge

Awards increase awareness of your business while offering third-party validation and establishing market leadership. This, in turn, significantly bolsters your sales activities.

03

Awards boost the morale of your employees

Employees enjoy being part of a recognised team, and recognition from an outside source, such as a respected industry brand, will spur even more impact than internal recognition.

04

Awards attract talent to your business

A company’s success depends on its staff. Workforce retention can be an ongoing challenge. When candidates see that your company is ranked as an industry leader, you’ve made your business even more attractive to potential hires.

05

Awards secure valuable publicity for your business

Industry awards can be a valuable addition to your marketing arsenal. The publicity an award-winning business receives can result in more business and new connections, helping validate what your company does and increasing your visibility in the marketplace.

Judging

Judging Process

Categories will be judged by a small group of judges and they’ll be assigned based on judges’ expertise and always avoiding any conflicts of interest. Judges will read and score their allocated entry forms, considering any supporting materials submitted. Judges will be asked to give a score for each question within the entry form. These will be combined to give an overall score for each entry. All judges’ scores will then be combined, and only the highest-scoring entries will determine the shortlists. Judges will e-meet to discuss the highest-scoring entries and then agree on the winner for each category. Judges may, at their discretion, award a high commendation on each category.

The shortlists will be announced on Monday 1st September. The winners will be announced at the awards ceremony on Thursday 6th November.

Confidentiality & Impartiality

To ensure that our awards are impartial, ethical, and transparent, we ask that our judges sign a charter agreeing to:

  • dedicate sufficient time to reading, judging and scoring the entries
  • delete all judging materials and marks immediately after the judging period
  • declare any conflicts of interest
  • not allow personal relationships or experiences to influence judging
  • keep judging discussions confidential and contained only to the judging panel
  • not share confidential material, judging papers or entries with anyone
  • not notify anyone that they have won or that they are shortlisted ahead of the official announcements
  • not give any feedback to entrants as to why they have not won or were not shortlisted – all requests for feedback must be directed to Tamarindo.
