Wheeling allows for the procurement of clean energy through national grid infrastructure
HOW WHEELING WORKS
1 – Generation Facility
Wheeling involves a generation facility producing electricity which is transmitted into a national grid and taken off in a grid.
2 – Wheeling Agreement
Wheeling agreements outline pricing, terms and conditions to enable the transmission of electricity from generators to off-takers.
3 – Transmission and Distribution
Generated electricity is injected into the transmission grid at the point of connection. The transmission system consists of high-voltage power lines that transport electricity over long distances. Electricity is then stepped down through transformers and distributed to the off-taker through the local distribution network.
4 – Metering and Settlement
Metering devices measure notional electricity transmitted from the generator to the off-taker. Accurate metering ensures accurate billing and settlement between the generator and the receiving entity.
BENEFITS OF WHEELING
Wheeling allows off-takers access to clean energy from high resource regions which may be geographically distant. It enables renewable energy generators to supply electricity to high demand centers and energy-intensive users.
Wheeling allows off-takers the ability to consume lowest cost electricity (Solar PV) from the national grid through notional price off-sets in off-taker national utility bills.
Wheeling optimises national grid infrastructure by enabling renewable energy integration, clean energy adoption and curtailment reduction.
Wheeling promotes clean energy adoption by enabling renewable energy project investment.
KEY CONSIDERATIONS
Wheeling is subject to regulatory frameworks that vary by country. NSE understands the intricate requirements governing wheeling across multiple regions.
Transmission capacity of the existing grid infrastructure needs to be assessed to determine the feasibility and limitations of electricity wheeling. Grid studies and coordination with transmission operators are necessary to ensure that the transmission system can accommodate the desired level of electricity transfer.
Wheeling agreements involve charges for the use of transmission and distribution infrastructure. These charges may include transmission fees, distribution fees and other associated costs.
Compatibility between the generation facility and the grid is crucial to ensure optimal transmission of electricity. Technical requirements such as voltage levels, frequency regulation and power quality standards must be met to ensure grid stability and reliability.
Navigating the complexities of electricity wheeling require expertise in power system planning, regulatory compliance and contract negotiation.
