The TidGen Power System generates emission-free electricity from tidal currents and connects directly into existing grids using smart grid technology. The power system consists of three major subsystems: shore-side power electronics, mooring system, and turbine generator unit (TGU) device. This submission includes the Advanced TidGen cost and cost of energy metrics after critical design review for BP1, and a complete LCOE content model and LCOE reporting according to DOE guidance for the baseline system and the system with advanced technology integrated. A revised LCOE content model is also included, with more relevant market array assumptions. Additionally, this submission includes a complete system overview and component overview content models. The LCOE Content Model provides data submitters with an easy and consistent means of uploading data that can be used to calculate the levelized cost of energy for MHK devices. Data represents the design completed for the Critical Design Review conducted at ORPC in December, 2017. All values are for a single device. Note that with substantial fixed costs, larger arrays will greatly reduce LCOE. For an array in Admiralty Inlet producing 136,000 MWh, 270 devices with an array CAPEX of $540,260,052 and an array OPEX of $39,959,207 would result in an LCOE of $722/MWh.
The directory helps financial sector stakeholders identify important and relevant climate-related data sources to meet their needs and facilitate access to these data. It also facilitates the identification of potential data gaps (where raw data items needed to construct a metric are not available) and creates incentives to bridge such gaps. As a living catalogue of available climate-related data sources for financial sector stakeholders, the directory is a public good. Besides, in fostering the establishment of comparable and consistent climate data, the directory can support the implementation of the International Sustainability Standards Board (ISSB) global standards. Hence, the NGFS hopes it will be used widely by financial sector stakeholders and the public globally, as a widespread adoption will in turn allow users to feedback to NGFS on the latest data sources and sustain the relevance of the directory. They urge all interested participants to take advantage of this new tool and leverage it to effectively green the financial system.
