But until the power units have become ready, BP and OOC are to connect their system to the existing Mussallim facilities through a power line called 132kV Inter-tie
, this will include the extension of the Mussallin sub-station with an additional bay on its eastern side to supply Khazzan including all the protection relays and UPS system and batteries.
This includes providing support and technical land assistance for a region-wide electrical power inter-tie
The simple economics of electricity supply therefore tells us these systems will likely voluntarily inter-tie. Larger connected retail markets may attract creation of lower-cost generation sources that require economies of scale.
Therefore, some small distribution companies might prefer to use DC connections to inter-tie to larger alternating current networks, avoiding the cost of meeting the AC connection standards.
DC inter-ties are also growing in use between AC systems of differing technical quality in Eurasia and with differing regulatory philosophies, such as between the Electric Reliability Council of Texas (ERCOT) and other adjacent grids in North America (see Steering Committee of Cities 9.011:19 and United Nations 200.5:29 ff).
He said: "I remember going to the Inter-Tie
held in what is now Centre Square in Middlesbrough.
At times, the country generates an excess of electricity, which is sold to other Central American countries using an electrical-transmission inter-tie
At a total cost of $237 million, the Second Supply Project will include modifications to the Tacoma Water Green River Headworks, a 34-mile pipeline from the Headworks to Tacoma with an inter-tie
to Seattle's Cedar River Supply System, new water treatment facilities, a new fish rearing facility and numerous environmental enhancement projects.
Grid inter-tie battery back-up systems currently comprise the majority of residential systems.
Grid inter-tie battery-free systems represent the area of greatest growth in the PV industry.
