Several key factors make Offshore Accumulating Power Stations (OAPS) particularly relevant for companies utilizing renewable energy sources (RES):

1. Grid Balancing
   OAPS enables the stabilization of electricity generation fluctuations, which is especially critical as the share of intermittent RES (wind and solar) increases. During periods of excess generation (daytime and nighttime), OAPS stores energy and releases it into the grid during peak demand hours.

2. Enhanced Reliability and Resilience of the Energy System OAPS acts as a reserve capacity that can be rapidly activated in response to sudden load changes or grid failures. This enhances grid stability and reduces the risk of power outages.

3. Economic Optimization

   • OAPS minimizes energy losses during periods of low consumption.

   • It allows more efficient utilization of large base-load power plants (nuclear and thermal), which operate most efficiently under stable loads.

   • It enables energy arbitrage by storing electricity when prices are low (nighttime and daytime) and selling it at higher prices during peak demand (morning and evening).

4. Reduced Dependence on Fossil Fuels
   The use of OAPS decreases the need for rapid-response fossil fuel power plants (gas and coal), leading to lower CO₂ emissions and a more environmentally sustainable energy system.

5. Government Incentives and Green Image
   In many countries, OAPS projects qualify for subsidies and incentives as they contribute to RES integration and decarbonization. This not only provides financial benefits but also strengthens the reputation of energy companies.

6. Longevity and Low Operating Costs
   Unlike battery storage systems, OAPS has a lifespan exceeding 25 years with relatively low operational expenses, making it a cost-effective long-term investment.
