Abstract
The National Offshore Wind Research and Development Consortium (NOWRDC) evaluated how the innovations it supports affect the levelized cost of energy (LCOE) and key performance metrics such as annual energy production (AEP), operational expenditures (OpEx), and capital expenditures (CapEx). This analysis builds on NOWRDC's 2024 LCOE Impact Report, which established the modeling framework and baseline assumptions used here. By modeling these innovations across three representative offshore wind farms reflecting the expected trajectory of U.S. offshore wind development in the 2030s, the analysis shows compelling results.
The methodology proceeds through three phases. First, three hypothetical baseline wind farms are constructed using public data, expert input, and inflation adjustments to represent distinct U.S. site conditions. The 2026 baselines place greater emphasis on floating offshore wind than the prior cycle, reflecting lease area awards on both coasts and the fact that roughly 60% of the U.S. offshore wind resource sits in waters too deep for fixed-bottom foundations. Second, NOWRDC-funded projects are screened for inclusion using three criteria: full project closeout, completion of a credible techno-economic analysis, and plausible near-term commercial viability. Only projects meeting all three criteria are carried forward into modeling. Third, each qualifying innovation is applied to the relevant baseline(s) to estimate its effect on LCOE, with granularity added as needed to capture specific cost drivers. Assumptions are informed by direct innovator interviews and stakeholder input from both U.S. and European sources, and a sensitivity analysis is conducted for each innovation. A notable finding in this cycle is that the most significant cost reduction opportunities appear in CapEx and OpEx rather than energy production gains, reflecting the fundamentally different cost structure of floating offshore wind.
Our analysis found NOWRDC R&D projects are driving cost reductions through three complementary mechanisms: reducing the cost of capital that makes offshore wind viable to finance, lowering the CapEx of mooring systems critical to floating deployment, and improving operational efficiency across all project types.
