In this sрent nuclear fuel case, the United States Court of Federal Claims entered *1349 a damages judgment in favor of PlaintiffAppellee Pacific Gas & Electric Company (“PG & E”). Because the new judgment accounts for the proper causation times and principles, this court affirms the trial court’s decision.
I.
This court heard this case earlier and will not repeat the complete factual background.
Pac. Gas & Elec. Co. v. United States,
On remand, the trial court “focuse[d] on whether the costs claimed as damages by PG & E were incurred as a direct and reasоnably foreseeable result of defendant’s partial breach of the [Standard Contract].”
Pac. Gas & Elec. Co. v. United States,
(1) costs incurred related to the evaluation of storage options and the licensing and construction of an independent spent fuel storage installation (ISFSI) and temporary racks at its Diablo Canyon power plant; (2) costs incurred for maintaining its Humboldt Bay рower plant in custodial [safe storage (“SAFSTOR”) ] status after 1998; (3) costs incurred in the licensing and construction of an ISFSI at its Humboldt Bay plant; (4) incremental costs of removing the ventilation stack at its Humboldt Bay plant while spent fuel continued to be stored in the spent fuel pool; (5) evaluation of Private Fuel Storage (PFS) off-site storage options for both plants; and (6) internal and external legal costs related to the аctivities contained in the other categories.
Id. at 180. The Government did not dispute the amount of damages in each category, but continued to dispute PG & E’s entitlement to those damages. Id. Indeed the Government “acknowledge^] that PG & E [was] entitled to recover approximately $82 million of its approximately $92 million in damages claims on remand.” Id. Specifically, under the 1987 ACR, the Government acknowledged that “PG & E [was] entitled to recover on remand the following costs: (1) Humboldt Bay SAFSTOR costs from 2000-2004, in the amount of $38,678,000; (2) Humboldt Bay ISFSI costs in the amount of $7,945,000; (3) Diablo Canyon ISFSI costs in the amount of $31,734,000; (4) Diablo Canyon temporary rack costs in the amount of $2,663,807; and (5) Diablo Canyon Storage Options study costs in the amount of $1,451,091.” Id. The trial court found that PG & E would not have incurred these reasonably foreseeable costs but for the Government’s breach. Id. at 182. The trial court also found that the record supported these amounts with reasonable certainty. Id.
On remand, the trial court focused on the disputed costs, i.e., Humboldt Bay SAFSTOR costs in 1999, Humboldt Bay ISFSI costs for Greater Than Class C waste (“GTCC”), evaluation of PFS off-site storage, costs associated with stack removal, as well as internal and external legal costs. Id. at 182-203. With respect to the 1999 costs at Humboldt Bay, the trial *1350 court determined that the Government’s partial breach caused PG & E to incur $4,744,000 in SAFSTOR costs. Id. at 183-86. The trial court then offset this amount by the amount PG & E wоuld have paid to exchange its 1999 allocation for an allocation right in the 1998 priority queue. After this offset, the trial court awarded $4,044,000 for the Humboldt Bay SAFSTOR costs in 1999. Id. at 188-89.
Concerning the Humboldt Bay ISFSI costs for GTCC, the trial court, consistent with this court’s decision in
Yankee Atomic Electric Co. v. United States,
The trial court upheld its previous denial of the stack removal costs because the “more persuasive testimony” supported the finding that PG & E would have removed the ventilation stacks for safety reasons. Id. at 197-98. Therefore, the application of the 1987 ACR did not impact this earlier finding. Id. Finally, the trial court determined that the mandate from this court and the statute of limitations barred the claim for internal and external legal costs because this claim could have been presented at the initial trial but PG & E waited to present this claim for the first time on remand. Id. at 199-202.
After totaling the damages award, the trial court set the amount for PG & E at $89,004,415. Id. at 204. The Government timely filed its appeal of the trial court’s decision. On appeal, the Government contends that the earlier mandate barred the trial court’s award of damages for the PFS and the Humboldt Bay SAFSTOR 1999 costs based on an exchanges model. As such, the Government appeals $4,933,517 of the trial court’s damages award. This court has jurisdiction under 28 U.S.C. § 1295(a)(3).
II.
This court reviews an interpretation of its own mandate without deference.
Laitram Corp. v. NEC Corp.,
Further, this court reviews the trial court’s legal conclusions without deference,
Yankee Atomic,
III.
The Government contends that the trial court erred by interpreting this court’s mandate to allow for reconsideration of PG
&
E’s claims for PFS damages and the 1999 Humboldt Bay SAFSTOR damages. In the original trial, the Court of Federal Claims found that PG & E entered into PFS “in the ordinary course of business, while it continued to be possible that DOE would perform the Standard Contract ...” and this venture was “highly speculative and uncertain.”
Pac. Gas & Elec. Co. v. United States,
Again, this court changed the time to begin assessment of the Government’s partial breach. This change gave the trial court “the opportunity to calculate the damages owеd to PG
&
E for DOE’s partial breach of the Standard Contract.”
Based on this instruction, the trial court properly undertook the task of reconsidering PG & E’s mitigation efforts. This task included another examination of issues properly before the court in the original trial, but, of course, did not extend to damages sought for the first time on remand, e.g., the internal and external legal costs. Within this general procedural setting, this court observes first that the issue of PFS off-site storage wаs properly before the trial court in the first trial. Moreover, nothing in this court’s 2008 decision considered, let alone adopted, the trial court’s earlier analysis with regard to PFS. Thus, the trial court retained full discretion to revisit and reconsider the PFS issue. “For while a mandate is controlling as to matters within its compass, on the remand a lower court is free as to other issues.”
Engel Indus., Inc. v. Lockformer Co.,
For these reasons, this court affirms the trial court’s determination that the damages claim for evaluation of off-site PFS storage was within this court’s mandate.
IV.
Because the trial court enjoyed the discretion to rehear the PFS issue on remand, this court rеviews the damages awarded in that category for clear error. On remand, the trial court found that PG
&
E’s duty to mitigate arose before 1998 when the Government breached the Standard Contract and that 1994 was the “latest possible date for the utility’s duty to mitigate, not the earliest.”
The trial court accurately stated the question as “[would] PG & E ... have been more likely than not to explore off-site storage in 1987.”
Id.
at 196. As such, the trial court determined that, in a non-breach world, PG & E would not have explored PFS in 1987 when the parties still expected the Government to perform. Therefore, the record showed that the trial court’s pre-remand finding that PG & E explored PFS “in the early 1990s in the ordinary course of business” could not stand. By the early 1990’s PG
&
E no longer expected timely performance by the Government.
Id.
Thus, in the early 1990’s PG & E already justifiably foresaw that the Government would not perform. The record also showed that PG & E had ample justification to prepare for the impending and foreseeable breach. The trial court determined that the “loss” caused by the Government was PG & E’s “continued need to store its spent fuеl in the absence of government performance under the parties’ Standard Contract.”
Id.
at 197. Accordingly PG & E was “not precluded from recovery to the extent that it has made reasonable but unsuccessful efforts to avoid loss.”
Id.
at 196-97 (internal citations omitted) (citing
Ind. Mich.,
For these reasons and based on the “preponderance of the credible evidence,” the trial court determined that the Government’s partial breach caused these foreseeable PFS costs.
Id.
at 195, 197. As this court previously determined and as properly noted by the trial court, PG & E is not precluded from recovering these damages because its mitigation efforts were unsuccessful.
See Ind. Mich.,
In
Indiana Michigan,
this court stated that “[m]itigation is appropriate where a reasonable person, in light of the known facts and circumstances, would have taken steps to avоid damage.”
In
Dairyland Power Cooperative v. United States,
this court acknowledged that a utility could receive damages for the cost of investing in a PFS to the extent that it was done for mitigation purposes.
Additionally, “[f]oreseeability is a question of fact reviewed for clear error.”
Bluebonnet Sav. Bank, F.S.B. v. United States,
The weighing of conflicting evidence is a task within the special province of the trial judge who, having heard the evidence, is in a better position than we to evaluate it. Particularly where, as here:
a trial judge’s finding is based on his decision to credit the testimony of one of two or more witnesses, each of whom has told a coherent and facially plausible story that is not contradicted by extrinsic evidence, that finding, if not internally inconsistent, can virtually never be clear error.
V.
This court now turns its attention to the trial court’s award of costs for PG
&
E’s 1999 Humboldt Bay SAFSTOR damages based on an exchangеs model. During the initial trial, PG
&
E asserted it would have used the exchanges provision to receive allocation rights in the priority queue for 1998 so that its SNF would have been removed before the impending SAFSTOR costs in 1999 in a non-breach world. Therefore, PG & E sought the costs associated with this mitigation effort.
On remand, the trial court stated that the 1987 ACR changed the nature of the parties’ “conduct and intentions.”
“Absent contrary instructions, a remand for reconsideration leaves the precise manner of reconsideration — whether on the existing record or with additional testimony or other evidence — to the sound discretion of the trial сourt.”
State Indus.,
VI.
This court now reviews the grant of the costs awarded for the 1999 Humboldt Bay SAFSTOR damages on remand for clear error. Based on PG & E’s expert testimony that a market for exchanges would develop and other evidence, the trial court determined:
Under the 1987 ACR acceptance rates, PG & E had sufficient allocations in years 1998 and 1999 that all of its Humboldt Bay SNF would have been picked up by DOE no later than 1999.... Through the use of exchanges, PG & E, to a reasonable certainty in the non-breach world, would have arranged for all of its SNF to be picked up in 1998, thereby avoiding SAFSTOR costs in 1999.
Under this court’s decision in
Yankee Atomic,
damages for partial breach of contract can only be awarded if the record shows that the breach caused the damages.
VII.
This court hereby affirms the trial court’s holding that the mandate did not bar the trial court’s reconsideration of PG & E’s claims for PFS and the 1999 Humboldt Bay SAFSTOR mitigation damages. This court affirms the damages awarded for PG & E’s PFS off-site storage and Humboldt Bay SAFSTOR 1999 mitigation damages.
AFFIRMED.
