ancillary services

Covering 15 states, the MISO area is one of the largest transmission networks in the US, yet solar and storage have had a battle to gain recognition in the territory.

Non-profit environmental law organisation Earthjustice has filed a complaint with the US Federal Energy Regulatory Commission challenging a rule that prevents renewables to provide ancillary services.

The fallout from February’s winter storm in Texas could see new legislation enacted that would shift the cost of ancillary services onto renewable energy projects, potentially derailing solar deployment in a state that is currently on track to surpass California and become the US’ leading PV market. Jules Scully speaks to the market to determine the risk posed to solar as a result.

Three US utilities have hit out at proposed changes to Texas’s energy market that they say would lead to new costs for solar facilities and curb investment in the state’s renewables sector.

Solar will likely play a major role in achieving Japan’s policy goal of reducing greenhouse gas (GHG) emissions to zero by 2050 and could reach 130GW to 160GW in cumulative deployments by the 2030 financial year.

US wholesale energy markets will be opened up to distributed energy resources (DERs) such as small-scale solar units and battery storage systems under a new ruling that proponents say will enhance grid reliability and lower costs for consumers.

India’s Union Cabinet has approved the signing of a memorandum of understanding (MoU) between Indian and US bodies to cooperate on integrating utility-scale renewable energy into the grid.
