Grids & Integration

The government has finally issued guidelines on how solar-powered irrigation system owners can be paid for exporting power back to the grid. However, for those who expect to have to use grid power to augment solar from time to time, there could be a sting in the tail.

The high-profile electric car maker is conducting a survey of German customers to gauge their interest in a Tesla electricity tariff.

The South African national power company is planning to deploy large scale energy storage capacity at the Skaapvlei substation. The facility will help manage the intermittent energy generated by a 100 MW Eskom wind farm.

Inverter manufacturer Fimer provided its PVS980-58 central inverter solution for the project, which will derive 35% of its energy from solar PV.

Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export limits, distribution static synchronous compensators, the replacement of old conductors in power grids, load reconfiguration, and dynamic voltage restoration.

CPS Energy has taken the first step towards bringing those volumes – plus 500 MW of firming capacity – to the Lone Star State in pursuit of the power company’s 50%-renewables-by-2040 goal.

Energy companies Shell and Eneco have secured the tender to build the 759 MW wind power plant. The partners will build a pilot solar park, short-term storage capacity and a green hydrogen plant at the facility, to assess their capabilities of balancing intermittent power.

The 182.5 MW/730 MWh Moss Landing energy storage system could eventually be expanded to 1.1 GWh – putting it on track to overshadow Tesla’s massive Hornsdale project in Australia.

The northern Australian region this week added nine solar plants to the two already threatened – along with a wind farm – with having their output halted under certain conditions.

Scientists from the Institute of Electrical and Electronics Engineers have presented research suggesting a new topology for residential solar+storage inverters.
