Mercury Completes 155 MW Kaiwera Downs Wind Farm in New Zealand
Mercury has opened Stage 2 of the 155 MW Kaiwera Downs wind farm, completing what reNEWS describes as the largest wind farm in New Zealand’s South Island. The commissioning strengthens Mercury’s renewable-generation portfolio and adds significant new wind capacity to New Zealand’s electricity system. Wind already plays an important role alongside the country’s hydroelectric generation, and additional capacity can help meet growing electricity requirements as transport and industrial activities become increasingly electrified. Completion of Stage 2 represents the key construction and commissioning milestone for the development following the earlier phase of the project. The 155 MW facility also demonstrates continued investment in New Zealand’s onshore wind sector as utilities seek additional renewable generation to support the country’s longer-term decarbonisation and energy-security objectives.
Synera Secures Corporate PPA for 800 MW Formosa 6 Offshore Wind
Synera Renewable Energy Group has signed a corporate power purchase agreement with Star Trade covering electricity from its planned 800 MW Formosa 6 offshore wind project in Taiwan. The agreement provides another commercial offtake arrangement for the project and strengthens its revenue foundation ahead of financing and construction. Long-term corporate PPAs are particularly important for offshore wind developments because predictable electricity sales can improve project bankability and reduce merchant-price exposure. Taiwan is one of Asia’s leading offshore wind markets and is using renewable electricity to support both energy security and industrial decarbonisation. Formosa 6 represents a major future addition to Taiwan’s offshore capacity. The latest Star Trade agreement also demonstrates continuing demand from corporate electricity buyers for contracted renewable power from large offshore projects.
Ireland’s Summer Solar Electricity Generation Jumps 58%
Solar electricity generation in Ireland increased 58 percent during June, July and August 2026 compared with the same three-month period in 2025, demonstrating the rapidly increasing contribution of photovoltaic capacity to the Irish power system. The jump reflects continuing deployment of utility-scale and distributed solar projects as Ireland diversifies a renewable portfolio historically dominated by wind generation. Higher solar output can complement wind by producing electricity during daylight hours and summer periods, helping reduce fossil-fuel generation requirements. The growth also creates greater demand for batteries, grid upgrades and flexible electricity consumption capable of responding to changing renewable output. Ireland’s 58 percent year-on-year summer increase shows that solar is moving from a relatively small part of the electricity mix toward a more meaningful component of the country’s renewable-generation portfolio.
