Product Details: The proposal in question involves the Aroostook Renewable Gateway Project, an infrastructure plan to transmit energy generated by wind farms in Aroostook County to consumers in southern Maine and Massachusetts. The project would utilize roughly 150 miles of high-voltage transmission lines through central Maine. It was initially supported by the Maine Public Utilities Commission and the state Legislature, and approved by Gov. Janet Mills as part of the goal to achieve 100% renewable electricity by 2040. However, the project was ultimately rejected by the commission due to concerns over escalating costs and project delays, with an estimated cost of $1.8
billion.

China’s Power Grid Systems
Product Details: China’s power grid system operates on two wide area synchronous grids: the State Grid in the North and China Southern Power Grid in the South. The grids face the challenge of redistributing power from resource-rich inland regions to densely populated coastal areas. China has diverse energy resources, including hydropower in the Southwest, wind energy in the North, Northwest, and Northeast, solar photovoltaic equipment in the Northwest, North, and East, and nuclear power plants in the southeastern coastal areas. Coal remains a significant fuel for thermal power due to its transportability and cost-effectiveness. The ‘Power Transmission from the West to the
East’ plan, introduced in 2005, aims to develop ultra-high voltage (UHV) transmission systems to increase power transfer capacity.
Pros:
– Ultra-high voltage power lines can transmit up to five times more electricity wi…
– The installation of UHV lines helps in better handling of solar and wind variabi…
– Market-based tools, such as the nationwide Emissions Trading System (ETS) introd…
Cons:
– The current grid system faces significant challenges in redistributing power fro…

– The integration of renewable energy into the grid is complicated by the need for…
The U.S. Must Close the Long-Distance Power …
Product Details: The commentary discusses the gap in long-distance power transmission technologies between the United States and China. It highlights that the U.S. transmission system is at or near capacity in several states, restricting the addition of more electricity and the integration of renewables. China has taken a significant lead in developing technologies for ultra-high-voltage (UHV) transmission lines and submarine cables, with 34 UHV lines already in operation, whereas the U.S. has none. The U.S. Department of Energy has identified the need for a 60% expansion of the U.S. transmission system to support high levels of renewable energy deployment.
Pros:
– Improved transmission infrastructure can lower power prices and reduce power out…
– Addressing the transmission gap can mitigate national security risks associated…
– Enhanced transmission capacity supports the integration of renewable energy sour…
Cons:
– The current transmission capacity limitations can lead to severe consequences, s…
– China’s technological lead in transmission technologies could allow it to set ma…
