The present disclosure provides an energy management system capable of improving energy efficiency. The energy management system includes: a fuel cell configured to supply energy used in a facility; a first hydrogen supply unit configured to supply hydrogen to the fuel cell by causing a power generation apparatus that uses renewable energy to perform water electrolysis; a second hydrogen supply unit configured to supply hydrogen to the fuel cell by reforming natural gas supplied via a pipeline; and a control unit configured to determine a ratio between hydrogen supplied from the first hydrogen supply unit to the fuel cell and hydrogen supplied from the second hydrogen supply unit to the fuel cell. The control unit determines the ratio in accordance with a percentage of heat energy and energy other than the heat energy with respect to the energy used in the facility. 本发明提供能够使能量效率提高的能量管理系统。能量管理系统具备：燃料电池，其供给在设施中使用的能量；第1氢供给部，其通过使用了可再生能量的发电装置来进行水电解，并向燃料电池供给氢；第2氢供给部，其对经由管道供给的天然气进行改性，并向燃料电池供给氢；以及控制部，其决定对燃料电池供给的氢中的、从
