“…Particularly, capital costs for wave energy plants are subdivided into PTO, structure, mooring, infrastructure, installation and permitting and environment expenses (Previsic, 2012), each one with a percentage weight, with reference to the overall costs, depending on the plant capacity. Operating costs, instead, are mainly due to operations, replacement parts, marine monitoring and insurance expenses.…”

“…Operating costs, instead, are mainly due to operations, replacement parts, marine monitoring and insurance expenses. In actual analysis, the applied cost breakdown is listed in Table 9, for three different plant capacities, namely 5, 25 and 50 MW, according to Previsic (2012).…”

“…Spain expects LCOE for that period of time of 21-33 c€/kWh [30]. Previsic et al [31] have pointed in a similar manner to a commercial opening cost of electricity for wave power in the order of 20-30 c€/kWh. Until 2020, DECC projects LCOE for onshore wind in the UK of 9-15 c€/kWh and projects LCOE for offshore wind of 13-22 c€/kWh.…”

a b s t r a c tTidal current and wave power have made substantial progress towards commercialisation. Based on the successful testing of full-scale prototypes, pioneering tidal arrays are currently implemented by means of direct agreements between developers/ investors and device manufacturers. The top-ranked risks for commercial projects (identified as achieving funding and uncertainty in device performance) are directly intercorrelated as investor confidence mainly depends on track records of continuous device operation. Before becoming recognised as a fully mature electricity generation method, marine energy needs to prove a range of referenceable project cases. The attainment of this array-scale success will represent a major turning point for the global marine energy business and is expected to finally trigger large-scale deployment.

“…We assumed that a hydraulic PCC system with a conversion efficiency of 82.5% was used for the OSWEC designs, which followed the assumption used in RM 3 ). The rated power was estimated based on a capacity factor of 30% (Previsic et al 2012;RenewableUK 2010). The resulting electrical power matrix for the RM5 design is shown in Table 6.…”

This report is an addendum to SAND2013-9040: Methodology for Design and Economic Analysis of Marine Energy Conversion (MEC) Technologies. This report describes an oscillating surge wave energy converter (OSWEC) reference model design and complements Reference Models 1-4 in the above report.A conceptual design for a taut, moored OSWEC was developed. The design had an annual electrical power of 108 kilowatts (kW), rated power of 360 kW, and intended deployment at water depths between 50 m and 100 m. The study includes structural analysis, power output estimation, a hydraulic power conversion chain system, and mooring designs. The results were used to estimate device capital cost and annual operation and maintenance costs. The device performance and costs were used for the economic analysis, following the methodology presented in SAND2013-9040 that included costs for designing, manufacturing, deploying, and operating commercial-scale MEC arrays up to 100 devices. The levelized cost of energy estimated for the Reference Model 5 OSWEC, presented in this report, was for a single device and arrays of 10, 50, and 100 units, and it enabled the economic analysis to account for cost reductions associated with economies of scale. The baseline commercial levelized cost of energy estimate for the Reference Model 5 device in an array comprised of 10 units is $1.44/kilowatthour (kWh), and the value drops to approximately $0.69/kWh for an array of 100 units. v This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www.nrel.gov/publications.
