UK electricity generated from offshore wind hit 5.1TWh in the first quarter of 2016, up 10% on the same period last year, according to government data.
However, onshore wind generation fell to 6.4TWh in the period, compared with 7.2TWh in the first three months of 2015.
The government said lower wind speeds “more than offset” increased capacity.
Overall, total electricity generated from renewables was 23.2TWh in the first quarter of the year, a 6.4% increase on last year.
Plant biomass increased 29% to 5.6TWh – mainly due to biomass conversion at Drax power station, the government said.
Solar showed the largest increase in percentage terms – 41% – to 1.3TWh.
Renewables share of UK electricity generation was 25.1% in the first quarter of 2016, up from 22.8% in the same period last year.
The growth was down to increased capacity, in particular, onshore and offshore wind and solar, the government said.
Total renewables capacity stood at 31.2GW at the end of the third quarter, up 12% on the same time last year and 2.4% higher than the previous quarter.
Solar increased 1.7GW, onshore wind 0.7GW and offshore wind 0.4GW in the period, compared with the first three months of 2015.
