Our mission is to develop and run a worldwide market-leading network for renewable energy trading, where the counterparts share the same possibilities to access good trading opportunities, using a cost- efficient and user-friendly solution. Who are we? We are an interest-sharing network enabling you to deal and chat directly with any trusted IREC, GO or Elcert counterparty – and settle contracts cost-efficiently using our built-in portfolio management tools. Green Power Hub helps you grow your green power business using a purpose-made network listing GOs and Elcerts, initially. Our aim is to add new markets – categorised as physical – in due course. The “Hub” in Green Power Hub literally means the “effective centre of an activity or network”. And that is precisely our aim: to enable Europe’s most liquid, efficient and user-friendly network for all stakeholders in the green electricity markets. Green Power Hub allows you to freely invite counterparties to trade bilaterally Elcerts and GOs (EECS and I-RECS) of any size, origin, technology or volume, on a fully transparent network. Our purpose-built chat function improves user-friendliness further. Subscription-based, no transaction fees What is furthermore unique to our network is the ease and low cost of doing bilateral deals. You pay no transaction fees, only a company-wide membership. If you do not want to trade, but only view prices, we also have a membership option for that. Recently, we also added a subscription package for Domestic trading only, meaning it is restricted by country. Portfolio management Efficiency and transparency matter whether you are a big or a small player, and Green Power Hub facilitates the management of your GO (EECS/I-REC) and/or Elcert portfolios. With one click you get an overview of your exposure in the market and trading history. And a streamlined online process replaces the paperwork normally associated with bilateral deals.
