Please help me write a proper abstract based on the patent claims. CLAIM: 1. (canceled) 2. A condition determination system, comprising: an operation condition data obtaining unit that obtains operation condition data indicating an operation condition of a facility; a determination unit that determines, based on the operation condition data, a level of a phenomenon that occurs due to the operation condition of the facility; and a storage unit that stores therein relation data indicating a relation between the operation condition of the facility and the level of the phenomenon, wherein the determination unit determines the level of the phenomenon, based on the operation condition data and the relation data. 3. The condition determination system according to claim 2, comprising: a display control unit that generates display data, based on a result of the determination by the determination unit, and causes a display unit to display thereon the display data. 4. The condition determination system according to claim 3, wherein the operation condition data obtaining unit obtains the operation condition data of each of plural facilities, the determination unit classifies, based on the plural sets of operation condition data, the plural facilities into normal facilities and abnormal facilities, and the display control unit causes the display device to display thereon the normal facilities and abnormal facilities in different designs. 5. The condition determination system according to claim 4, wherein the facilities include a storage battery power source, the operation condition data include remaining capacity data indicating a remaining battery capacity of the storage battery power source, and the display control unit causes the display device to display thereon the remaining capacity data. 6. The condition determination system according to claim 4, wherein the facilities include a storage battery power source, the operation condition data include power feedable time data indicating a time period, over which the storage battery power source is able to feed power, and the display control unit causes the display device to display thereon the power feedable time data. 7. The condition determination system according to claim 4, wherein the facilities include power sources, and the display control unit causes the display device to display thereon the plural power sources correspondingly to capabilities of the power sources, respectively. 8. The condition determination system according to claim 4, wherein the facilities include power sources, and the condition determination system includes: a characteristic data obtaining unit that obtains characteristic data of each of the plural power sources, the characteristic data including power feeding capabilities thereof; and a power source management unit that elects, based on necessary power data indicating power necessary for electric devices to operate and the characteristic data, the power source to be assigned to a specific electric device, and the display control unit causes the display device to display thereon the power source elected. 9. The condition determination system according to claim 4, wherein the facilities include an existing power source, and a portable power source that substitutes for the existing power source, the condition determination system includes a position data obtaining unit that obtains position data indicating a position of the portable power source, and the display control unit causes the display device to display thereon the position data. 10. The condition determination system according to claim 9, wherein the portable power source includes a storage battery power source, and the display control unit causes the display device to display thereon remaining capacity data indicating a remaining battery capacity of the storage battery power source. 11. The condition determination system according to claim 9, wherein the portable power source includes a storage battery power source, and the display control unit causes the display device to display thereon power feedable time data indicating a time period, over which the storage battery power source is able to feed power. 12. A decision-making support system, comprising: the condition determination system according to claim 2; and an information management unit that shares, via a network, abnormality data including the operation condition data necessary at the time of abnormality, wherein the decision-making support system supports decision-making for measures at the time of abnormality. 13. The decision-making support system according to claim 12, wherein the information management unit distributes report data generated based on the level of the phenomenon. 14. A condition determination method, including: obtaining operation condition data indicating an operation condition of a facility; determining, based on the operation condition data, and relation data indicating a relation between the operation condition of the facility and the level of the phenomenon, a level of a phenomenon that occurs due to the operation condition of the facility, the relation data being stored in a storage unit; and generating, based on a result of the determination of the level of the phenomenon, display data, and causing a display device to display thereon the display data. 15.
