Executive Viability Abstract
This study evaluates the feasibility of developing offshore wind energy infrastructure in New Zealand, focusing on Taranaki and Waikato regions. With New Zealand's target of 100% renewable electricity by 2030, offshore wind presents a multi-gigawatt opportunity to complement existing hydro and geothermal baseloads.

## Executive Summary
New Zealand possesses one of the best offshore wind resources globally. This project aims to establish a 1GW initial capacity off the South Taranaki Bight.
## Market Analysis
New Zealand's electricity demand is projected to grow by 15-40% by 2050 due to transport and industrial electrification. Currently, the market is dominated by hydro (60%), which is vulnerable to 'dry year' risks. Offshore wind provides a more consistent generation profile during these periods.
## Technical Feasibility
Fixed-bottom turbines are viable in Taranaki (depths <50m), while floating foundations will be required for deeper sites. Port infrastructure in New Plymouth requires significant upgrades to handle large-scale turbine components.
## Revenue Model
Revenue is driven by a mix of Long-term Power Purchase Agreements (PPAs) with industrial users (e.g., green hydrogen producers), Wholesale Market Spot Pricing, and potential government-backed Contracts for Difference (CfD).
## Financial Projections
Estimated Capex is NZD $4.5B - $6.2B for a 1GW facility. LCOE is expected to fall between $90 - $130/MWh initially, trending down as local supply chains mature.
