Protests are being staged against three controversial wind farm applications which are being discussed by councillors in Powys.
The applications for Llanbrynmair, Llaithdu and Llandinam will be decided by the UK government because they are set to generate over 50 megawatts.
Powys council is debating the plans as a statutory consultee at a meeting being broadcast on the web.
Campaigners are demonstrating outside the meeting in Llandrindod Wells.
Opposition to wind farms has grown in Powys since plans were announced to build a 19-acre electricity sub-station in the county.
