TSO Link develops hardware and software that activates UPS systems and backup power in data centers as grid balancing resources. Through the TSObox unit and the TSOcloud platform, installed capacity is aggregated and traded on the FCR, FFR and mFRR markets operated by Nordic transmission system operators. Data center operators receive a revenue share with no operational involvement required. TSO Link is based in Stockholm and currently operates 1.1 MW of live capacity in Sweden.
