Powerhouse. Landlord is currently in the process of upgrading the electric infrastructure of the Entire Project (the “Powerhouse Upgrade”). A portion of the Powerhouse Upgrade includes additional electric infrastructure such that, upon completion, the electrical infrastructure that supports electrical power provided to Building 8 and Building 9 will be capable of supporting the amount of electrical power described in in the “Electrical Power Supply” line of Tenant’s load letter dated as of April 1, 2014 (and attached hereto as Exhibit A, the “Load Letter”) in connection with the Mt. Pleasant Lease (the “Mt. Pleasant Infrastructure”). When the Powerhouse Upgrade (or any portion thereof) is placed in-service, Tenant acknowledges that it is responsible for Tenant’s proportionate share (allocated in accordance with the final sentence of this Section) of the costs of the Powerhouse Upgrade (or such portion placed in-service) (in accordance with, and subject to, the Operating Expense provisions of the Mt. Pleasant Lease) allocated (as reasonably determined by Landlord) to the Entire Project and the Mt. Pleasant Project regardless of whether the Powerhouse Upgrade (or any portion thereof) has been placed in-service prior to the Building 8 Operating Expense Commencement Date or the Building 9 Operating Expense Commencement Date. In furtherance of the foregoing, in the event the in-service date of the Powerhouse Upgrade (or any portion thereof) is prior to the Building 8 Operating Expense Commencement Date or the Building 9 Operating Expense Commencement Date, then the Building 8 Operating Expense Commencement Date and/or the Building 9 Operating Expense Commencement Date, as applicable and only with respect to Operating Expenses in connection with the Powerhouse Upgrade, shall be deemed to be the in-service date of the Powerhouse Upgrade (or the applicable portion thereof). Tenant acknowledges that for purposes of determining the costs described above, the Powerhouse Upgrade will benefit the Buildings and is not subject to any of the Operating Expense carve outs set forth in Section 8.1(d)(a) of the Existing Mt. Pleasant Lease. Further, Tenant acknowledges that the costs of the Powerhouse Upgrade will be allocated across the Entire Project (including the Mt. Pleasant Project) in accordance with each building’s kVA capacity.

Powerhouse. Soil sampling was not previously conducted in the Powerhouse (Boiler Building) area given that the site characterization did not identify any concerns regarding potential contamination. In particular, the Powerhouse was one of the original site structures, with no known prior industrial activities in that area. Further, the Powerhouse had no floor drains or industrial wastewater system components, and was not used for the storage of pigment materials, such that sub-slab soil contamination was considered unlikely. As discussed above in Section 6, during removal of the Powerhouse slab and foundation members, an interval of fill material was observed directly beneath the slab. That material contained slab and/or cinders, and other anthropogenic items, comparable to material observed beneath the Ice Plant slab, and was therefore excavated and staged separately pending waste classification sampling. Apparently native soils were also excavated, from greater depths, as needed to remove the deep footers associated with this building and the former stack. These deeper soils were also staged, but separately from the soils containing non-native materials. Two waste classification soil samples were collected from these Powerhouse soils, one from the native soils and the other from the soils containing non-native materials. Analytical results from the waste classification samples indicated that the deeper, native soils did not contain metals or other constituents at concentrations above commercial-use SCOs and further, would be classified as nonhazardous waste. Conversely, the soils containing anthropogenic materials had concentrations of barium, copper and lead above commercial-use SCOs and a TCLP concentration of lead of 7.3 mg/l, indicating those soils were RCRA characteristic waste for lead. Based on the observation of non-native materials in the upper soil intervals in this area, and on the waste classification sample obtained from that material, residual soil contamination is potentially present in the Powerhouse area. As discussed above, a 6-ounce geo-textile liner was placed over the footprint of the building and site soils (that had been cleared for on-site reuse via prior sampling) were used as backfill to bring this area to nearly original grade, as needed to promote proper drainage and prevent surface water accumulation. Post-excavation soil sampling was not planned or completed as part of the demolition activities in this area. However, in light of the was...
Powerhouse. The 210 m long by 40 m wide powerhouse (Figure 4−6) will be anchored in bedrock on the south side of the river immediately downstream from the dam. The powerhouse will be above ground, enclosed in a metal−clad, concrete building with steel superstructure, its longitudinal axis approximately 30° to the river axis. Five turbines, each with a capacity of 450 MW, will provide a total installed capacity of 2,250 MW. The maximum discharge per turbine will be 590 m3/s. In turn, total discharge from the powerhouse will be 2,950 m3/s. The net head on the plant will be 86 m. The diameter of the Xxxxxxx turbine runners will be 7.2 m. The air−cooled generators will be directly coupled to the turbine shafts, with each generator connected to a power transformer via an individual isolated phase bus and generator breaker.
