Electricity Distribution Company of Lorestan Province

Lorestan Province is a province of western Iran in the Zagros Mountains. The population of Lorestan was estimated at 1,716,527 people in 2006.In 2014 it was placed in Region 4. Lorestan covers an area of 28,392 km2. The major cities in this province are Khorramabad, Borujerd, Aligoodarz, Dorud, Koohdasht, Azna, Alashtar, Noor Abad, and Pol-e-Dokhtar. The name Lorestan means "land of the Lurs". In the wider sense it consists of that part of western Iran coinciding with the province of Ilam and extending for about 650 km on a northwest to southeast axis from Kermanshah to Fars, with a breadth of 150–180 km. The terrain consists chiefly of mountains, with numerous ranges, part of the Zagros chain, running northwest to southeast. The central range has many summits that almost reach the line of perpetual snow, rising to 4000 m and more. It feeds the headwaters of Iran's most important rivers, such as the Zayandeh rud, Jarahi, Karun, Diz, Abi, Karkheh. Between the higher ranges lie many fertile plains and low hilly, well-watered districts. The highest point of the province is the Oshtorankuh peak at 4,050 m. The low-lying areas being in the southernmost sector of the province are approximately 500 m above sea level. Oak forest covers the outer slopes, together with elm, maple, walnut, and almond trees.[4] Western Luristan comprises a series of parallel fertile valleys running high in the Zagros mountains. The Pusht-i Kuh region is in the western foothills of the Kabir Kuh range. The Pish-i Kuh region lies to the east of Kabir Kuh. This area had human settlements during the Bronze Age as early as the mid–3rd millennium B.C. Climatically, the province can be divided into three parts: the mountainous regions, such as Boroujerd, Doroud, Azna, Nourabad and Alishtar experience cold winters and moderate summers. In the central region, the spring season begins from mid-February and lasts till mid May. The township of Khorramabad is in this realm. However, southern areas such as Pol-e-Dokhtar and Papi are under the influence of the warm air currents of Khuzestan, have hot summers and relatively moderate winters.[5] The climate is generally sub-humid continental with winter precipitation, a lot of which falls as snow (Köppen Csa). Because it lies on the westernmost slopes of the Zagros Mountains, annual precipitation in Lorestan is among the highest anywhere in Iran south of the Alborz Mountains. At Khorramabad, the average annual precipitation totals 530 millimetres (21 inches) of rainfall equivalent, while up to 1270 millimetres (50 inches) may fall on the highest mountains. The months June to September are usually absolutely dry, but Khorramabad can expect 4 inches of rainfall equivalent in December and January. Temperatures vary widely with the seasons and between day and night. At Khorramabad, summer temperatures typically range from a minimum of 12 °C (54 °F) to a hot maximum of 32 °C (90 °F). In winter, they range from a minimum of -2 °C (28 °F) to a chilly maximum of 8 °C (46 °F). The ancient history of Lorestan is closely intertwined with the rest of the Ancient Near East. In the 3rd and 4th millennium BC, migrant tribes settled down in the mountainous area of the Zagros Mountains. The Kassites, an ancient people who spoke neither an Indo-European nor a Semitic language, originated in Lorestān. They would control Babylonia after the fall of the Old Babylonian Empire ca. 1531 BC and until ca. 1155 BC. Luristan was invaded and settled by the Iranian Medes in the 2nd millennium BC. The Medes absorbed the indigenous inhabitants of the region, primarily the Kassites as well as the Gutians, by the time the area was conquered by the Persians in the 1st millennium BC. In February 2017, archeological discoveries related to the Achaemenid era were made in Lorestan for the first time.[8] Luristan bronze Small Luristan bronze artworks (always so spelled in English), usually dated about 1000 to 650 BC, reached the outside world from the late 1920s and are found in museums all over the world, where they are valued for their vigorous style, with many representations of animals. But actually, the beginning of this bronze-making tradition goes back to the mid–3rd millennium B.C, and it probably developed in Luristan, itself. Archaeologists characterized these techniques by the metallurgical analysis of different artifacts, We have characterized these practices by the compositional and metallurgical analysis of grave goods from several cemeteries in the region including six dating to different phases of the Bronze Age (Early Dynastic I to Ur ED III, circa 2900–2000 B.C.)—Kalleh Nisar, Bani Surmah, Chigha Sabz, Kamtarlan, Sardant, and Gulal-i Galbi—and four dating to different phases of the Iron Age (circa 1300 B.C.–600 B.C.)—Bard-i Bal, Kutul-i Gulgul, Sar Kabud, and War Kabud.[9] Technically, the term 'Luristan bronze' usually refers only to the later bronze objects, although they have many similarities. The earlier bronze objects were made during the Elam period. Lorestan was successfully integrated into the Achamenid, Parthian and Sassanian empires. Parts of the region managed to stay independent during the Arab, Seljuk and Mongol invasions. According to the Encyclopaedia of Islam, the Lurs, previously open adherents of the Ahl-e-Haqq faith, revere bread and fire like the Zoroastrians. "Being split up into numerous tribes and sections, they migrate to their summer pastures as separate bands without overall command. In 1936, Reza Shah's army conquered them, with much bloodshed and starvation, forcing many of the survivors to settle in villages under landlords."[10] In the early 1930s, when British explorer Freya Stark visited Luristan, she reported that few Europeans had visited the area before her, partly due to its remoteness, but also because of the dangers one could expect to encounter among lawless tribespeople.
