What changes to the local and regional electrical grid will be required and when?
UAMPS indicates that changes, if any, to the local and regional electrical grid are unknown at this time. When a site is chosen and finalized, UAMPS will initiate the following process with the transmission provider. It is anticipated that this process may take up to a year before it is complete and UAMPS would enter into an interconnection agreement.
The Interconnection of the CFPP to the electrical transmission system will be through the Large Generator Interconnection Process (LGIP) that is part of the PacifiCorp Open Access Tariff (OATT). The LGIP consists of interconnection and transmission studies that evaluate the effect of the generator on the existing transmission system and identify the interconnection facilities and transmission facilities that are necessary for the reliable operation of the generator and transmission system. After the LGIP is complete, a Large Generator Interconnection Agreement will be entered into for the construction of the interconnection facilities and any transmission system upgrades that are necessary. The LGIP and LGIA will also identify the allocation of the costs of the interconnection facilities and transmission facilities into two categories, Direct Assigned and Network Upgrade. For Direct Assigned facilities, UAMPS will be responsible for 100% of the costs. For Network Upgrades, the costs will be allocated to the transmission revenue requirement of PacifiCorp, although UAMPS may have to provide upfront funding of the upgrades.
