The Canadian utility HydroQuebec (HQ) has proposed three transmission projects either 100% hydropower-based or rather relying on hydro-wind power supply blend in order to supply power to Massachussets (US). The three proposed transmission schemes are the Northern Pass Transmission (NPT) plan, the New England Clean Power (NECP) Link and the New England Clean Energy Connect line (NECEC). This proposal is HQ response to the March 2017 Request for Proposals (RFP) launched by several Massachusetts’ electric distribution companies procurement of clean-energy based power supplies which are meant to help the state reduce its energy costs and meet the target of 9.45 TWh of yearly renewable power production by 2022 . In each of HQ's hydropower/wind supply options, the power would be supplied by hydropower facilities alone or together with the 300 MW SBx wind park facility expansion, which would be the fourth phase of the Seigneurie de Beaupré Wind Park .
The 192 mile (308 km) NPT line would be a 1,090 MW and is scheduled to convey power from HQ hydroelectric power stations to Massachussets and New Hampshire. A new direct current (DC) line would be built from the Canadian border to Franklin (New Hampshire).
The NECP link transmission line project is a 1,000 MW line which would have a voltage of 300kV to 320 kV and would stretch from the Franklin county (US-Canadian border) down to the Windsor county (Massachussets).
The NECEC project is a 320kV HVDC transmission line from an interconnection at the Appalaches Substation in Québec (Canada) to a new converter station in Lewiston, Maine (US). If the project is endorsed, it would become operational in 2022. The project would spread on 145 miles (233 km).
The Seigneurie de Beaupré wind park is divided into four phases: Phase I (272 MW, parks 2-3, commissioned in 2013), Phase II (68 MW, park-4, commissioned in 2014), Phase III (23.5 MW, community park Côte-de-Beaupré, commissioned in 2015) and Phase IV (SBx, commissioning planned in 2021-2022).
