Willows 游泳俱乐部是一家私人, 位于新泽西州中部的会员拥有的游泳和娱乐设施. 游泳俱乐部为当地一家餐馆提供厨房空间以经营食品特许经营. 为其会员提供服务, 目前不收取租金或水电费. 然而, 鉴于当前的经济形势，游泳俱乐部正在考虑向特许经营者收取下赛季的费用，以补偿经营特许区所产生的公用事业费用. 此次能源审计的主要目标是测量特许区域的电力需求和能源消耗，以确定平均夏季高峰运营期间的需求和使用情况, 代表最坏情况的需求和能源使用. 该信息将用于在谈判下赛季合同时确定合理的公用事业费用.
游泳俱乐部是季节性营业，每年夏季从阵亡将士纪念日到劳动节期间营业. 特许权运作 7 每周几天，每天上午 11 点至晚上 7 点左右. 由于需求和其他因素，某些日子的营业时间会延长，但由于恶劣天气，营业时间也可能会缩短. 游泳池位于室外，因此设施可能会因下雨或气温较低而关闭或限制营业时间. 特许区电力负荷主要由冰箱等周期性负荷组成, 冰柜和室内空调，但存在头顶照明等恒定负载.
使用 Dranetz 进行为期两周的能源调查 能源平台EP1 从7月开始进行 14, 2009 到七月 28, 2009. The EP1 was connected to the dedicated 120V split phase sub panel feeding the concession area. Two model TR2550, 100A CT’s were used for current measurements.
Below is the demand profile recording during the survey with the Peak Demand overlaid. Data is show in DranView 6 软件:
Survey results indicated the following:
- Peak demand measured during the period was 7.353 KW.
- Total electricity consumed was 1375.6 KWh
- The survey ran for 13.95 days with an average consumption of about 98.5 KWh per day
- General observations
- The demand was cyclical and peaked during mid day hours as expected.
- More consistent demand profile was observed during the first week of the survey vs. the second week.
- Local weather data during the monitoring period was obtained from the Internet and compared to the demand profile. The comparison indicated rain and poor weather conditions corresponded with the reduction and inconstancy of the demand measured during the second week of the survey. Since such weather is consistent with a normal summer in the area this demand data should be included in the overall 2 weeks results being considered normal.
Electricity Cost Estimation
The local utility is Public Service Electric & Gas (PSE&ĝ) 公司. New Jersey, being a deregulated state provides consumers the option to purchase electricity supply from an independent provider other than the delivery company. The facility owner chose PSE&G as the electricity supplier so both Delivery and Supply charges come from the one utility. 尽管游泳俱乐部的用电规模相对较小，但公用事业账单比住宅账单更复杂. 所采用的公用事业费率结构是PSE&G的GLP, 一般照明 & 功率率. 也是电力供应商, PSE&G 向他们的 BGS 收费, 供电费的基本发电服务费率结构. 由此产生的公用事业账单展示了在放松管制的能源环境中计费的复杂性，以及了解您的用电量以管理和降低公用事业成本的重要性:
- 送货:
- 服务费: $4.27
- 配送费
- 年需求@ $3.9202/KW
- 夏季需求 @ $7.2755/KW
- 千瓦时收费 @ 0.0145 美元/千瓦时
- 社会效益 (收回实现政府政策所产生的成本)
- @ 0.0075 美元/千瓦时
- 证券化转型 (债券融资费用)
- @ $0.0104/KWh
- Supply:
- BGS Capacity (代 & 传输)
- This is a complex calculation that represents the customers share of the overall peak load assigned to the utilities transmission zone.
- BGS Energy (tiered usage per KWh)
- @ $0.1089/KWh (first tier <9755 KWh)
- BGS Capacity (代 & 传输)
Being such a complex rate structure with many billing factors, it can be difficult to relate some of these costs to actual usage by the concession. Since the objective is to estimate worst utility costs, a fair method was found with the following assumptions taken into account:
- The operation of the swim club during the 2 week survey was deemed typical and representative an average two week period during peak summer months.
- Actual usage results will be used in the estimated charges opposed to determining a percentage of the concession usage vs. the overall bill.
- 服务费将是 100% 由业主支付.
- BGS 容量费用将被忽略，因为没有公平的方法来确定这些费用的优惠部分. 业主将承担这笔费用.
- 各种千瓦需求和千瓦时能源公用事业费用可以合并为估算中千瓦和千瓦时部分的一项费用:
- 综合千瓦需求费用为: $11.1957
- 综合千瓦时能源费用为: $0.1413
