PO084: Cost-Modeling Approach of Offshore Battery Energy Storage System Integration for Hybrid Wind Farms.
Vincent Bonnin, Energy Solution Analyst, Dutch Marine Energy Centre
Abstract
Energy storage can play a crucial role in supporting the offshore wind sector by addressing several emerging challenges, including congestion-related curtailment, price volatility, and revenue erosion. Additionally, there are strong arguments for co-locating storage assets offshore alongside wind farms, primarily to enhance the utilisation of export infrastructure that is being deployed over increasingly long distances from shore. This study examines the sizing and cost of an enlarged offshore substation that would host a containerized battery energy system, and explores the conditions under which the resulting reduction in export infrastructure can deliver improved cost-effectiveness. Mass and cost estimation models were developed for all components of the balance of plant in the case of an HVDC export infrastructure architecture, including offshore and onshore substations, cables, storage system and supporting systems. A study case is built around a fictive wind farm located in the North Sea (750 MW, 50 turbines, 56 km offshore) with a 700MW export infrastructure. Wind production and curtailment data are simulated using DMEC’s tool MultiORE. The energy storage capacity is sized by ensuring that curtailment remains at its baseline level despite a stepwise reduction in export cable power. For each corresponding energy system size, both capital expenditure and operational expenditure costs are calculated for two scenarios: with and without offshore storage. For the baseline case, the addition of above-water energy storage is unlikely to enhance the cost-effectiveness of the co-located wind plant. However, a sensitivity analysis of cable length, battery energy density, and storage system cost is conducted to identify the conditions under which offshore storage could deliver cost savings.
