Why Energy Storage Systems (ESS)? Consequences of Disruption – Australia: similar scenario likely
18
Why Energy Storage Systems (ESS)? Consequences of Disruption 1. Growth of Renewable energy, especially solar PV and wind, is unstoppable (driven by pollution, climate change, power shortages and falling costs). 2. Conventional Electricity business model based on fossil fuels facing death spiral. 3. Higher penetration of renewables in the electrical network require solutions to minimise variability, stabilise the grid and ensure reliability across the network (generation to customer’s end). Solution 1. Energy storage (electrical and thermal) is a key element among feasible solutions. 2. Value of storage is more pronounced as costs are falling. 19
