3月22日，從山東電力調度中心獲悉，隨著氣溫穩步回升，山東電網平穩度過冬季用電高峰。受工業用電負荷強勁增長與電源建設相對滯后影響，預計二季度至年底，山東全省電力供應將持續吃緊，夏季缺口約為300萬千瓦，冬季缺口約為500萬千瓦。山東電力集團公司超前應對供電趨緊形勢，多措并舉，全力確保電網安全運行和電力有序供應。
根據山東公司編制的《2012年山東電網電力平衡報告》顯示，2012全省電力能源消耗仍將保持較高增長水平，全年統調最高負荷將達5500萬千瓦，同比增長12%。相對于需求的快速增長，電源建設卻相對滯后，全年新增發電裝機容量308萬千瓦，增速僅為6%。不考慮電煤供應緊張等不可控因素影響，經平衡分析，從4月上旬開始出現電力缺口。臨沂、棗莊、青島等地區確保電力供需平衡壓力較大。
在電力供應日益緊張的同時，電網安全運行壓力也不斷增大。當前，山東電網已步入大容量、高參數、交直流混合的大電網運行格局，銀東直流一旦雙極閉鎖，全網將被迫瞬間切除負荷125萬千瓦。同時，由于山東省燃煤機組容量高達96%，且近一半是熱電聯產機組，調峰能力差，電網最大峰谷差接近1500萬千瓦。而隨著供熱機組比例不斷上升和風電等新能源的大規模接入，電網調峰、調頻、調壓的壓力進一步加劇，大面積停電的風險依然存在。
