挑战
Enexis 是一家独立的电网运营商，也是荷兰最大的能源分销商之一。它与能源供应商合作，为七个省的客户管理 200 万个天然气和 260 万个电力连接，约占荷兰市场的三分之一。 2008 年，欧盟 (EU) 指令规定，到 2020 年，80% 的能源客户必须能够监控能源消耗。荷兰政府做出回应，要求能源运营商在家庭中安装智能计量技术。为了实现这些目标，Enexis 将需要部署大约 500 万个智能电表，每个电表每天传输一次能源消耗数据。自 2011 年起，Enexis 不再安装传统电表，电网中安装的每一台新电表都是智能电表。这意味着在推出的最初几年，智能电表安装在整个电网中。为了实现这一目标，Enexis 有多种选择。通过电力线连接 (PLC) 路由数据是不切实际的，因为为了有效地工作，整个地区必须同时安装智能电表。由于最初的推广仅限于更换故障仪表和新装置，因此这是不可行的。通过 WiFi 传输数据是另一种选择，这意味着房主需要有保证的连接。 “因为我们安装的智能电表分散在我们的配电网络中，所以最有效的解决方案是基于 M2M SIM 的 GPRS，”Enexis 智能电表运营经理 Lonneke Driessen-Mutters 说。安装在智能电表中的 M2M SIM 将能够通过沃达丰在荷兰的全面移动覆盖传输数据，无需房主参与，安装工作量最少。 Enexis 邀请了荷兰的多家移动通信供应商进行投标。经过慎重考虑，沃达丰是基于成本和服务承诺而被选中的。此外，Enexis 已经与 Vodafone 建立了合作关系，因为他们提供了该公司大约 3,000 个语音和数据连接，因此他们知道他们可以期待的服务。 “我们是地方政府所有的，所以我们的钱是公款。该解决方案必须具有成本效益，因为我们必须谨慎花钱，”Driessen-Mutters 说。

解决方案
沃达丰 SIM 卡集成到智能电表中，并与 Enexis 的数据中心之间传输能源消耗数据。一条短信每天“激活”智能电表，测量家中的能源消耗数据。然后智能电表通过 GPRS 传输数据，然后关闭。这降低了功耗并将传输成本降至最低。沃达丰的订购和激活系统支持 SIM 安装，使用基于 Web 的工具确保交付和管理大量 SIM。每个设备的实时信息，包括数据使用情况，都集成到 Enexis 后端系统中。 Vodafone 的 M2M 平台在 SIM 的整个生命周期内对其进行管理，包括解决方案设计和优化、物流、安装、客户服务和定制计费。最初的部署覆盖了 3,000 个智能电表，但后来扩展到大约 100,000 个位置，并计划在不久的将来再安装 150,000 个。这将是传统仪表的自然替代品，加上个人客户的要求，他们可以以 60 欧元的价格优先安装智能电表和燃气表。 “但是，如果我们只是根据客户的要求安装智能电表作为自然替代品，那么这种增长率将不足以满足欧盟的目标，”Driessen-Mutters 说。 “因此，我们将在某个时候通过挨家挨户安装智能电表来扩大推广范围。”

IoT Solutions for Smart City | Internet of Things Case Study
There were several challenges faced: It is challenging to build an appliance that can withstand a wide range of voltage fluctuations from as low at 90v to as high as 320v. Since the device would be installed in remote locations, its resilience was of paramount importance. The device would have to deal with poor network coverage and have the ability to store and re-transmit data if networks were not available, which is often the case in rural India. The device could store up to 30 days of data.

Automation of the Oguz-Gabala-Baku water pipeline, Azerbaijan
The Oguz-Gabala-Baku water pipeline project dates back to plans from the 1970’s. Baku’s growth was historically driven by the booming oil industry and required the import of drinking water from outside of the city. Before the construction of the pipeline, some 60 percent of the city’s households received water for only a few hours daily. After completion of the project, 75 percent of the two million Baku residents are now served around the clock with potable water, based on World Health Organization (WHO) standards. The 262-kilometer pipeline requires no pumping station, but uses the altitude differences between the Caucasian mountains and the capital to supply 432,000 m³/d to the Ceyranbatan water reservoir. To the people of Baku, the pipeline is “the most important project not only in 2010, but of the last 20 years.”

GPRS Mobile Network for Smart Metering
Around the world, the electricity supply industry is turning to ‘smart’ meters to lower costs, reduce emissions and improve the management of customer supplies. Smart meters collect detailed consumption information and using this feedback consumers can better understand their energy usage which in turn enables them to modify their consumption to save money and help to cut carbon emissions. A smart meter can be defined in many ways, but generally includes an element of two-way communication between the household meter and the utility provider to efficiently collect detailed energy usage data. Some implementations include consumer feedback beyond the energy bill to include online web data, SMS text messages or an information display in consumers’ premises. Providing a cost-effective, reliable communications mechanism is one of the most challenging aspects of a smart meter implementation. In New Zealand, the utilities have embraced smart metering and designed cost effective ways for it to be implemented. The New Zealand government has encouraged such a move to smart metering by ensuring the energy legislation is consistent with the delivery of benefits to the consumer while allowing innovation in this area. On the ground, AMS is a leader in the deployment of smart metering and associated services. Several of New Zealand’s energy retailers were looking for smart metering services for their residential and small business customers which will eventually account for over 500,000 meters when the multi-year national deployment program is concluded. To respond to these requirements, AMS needed to put together a solution that included data communications between each meter and the central data collection point and the solution proposed by Vodafone satisfied that requirement.

NB-IoT connected smart meters to improve gas metering in Shenzhen
Shenzhen Gas has a large fleet of existing gas meters, which are installed in a variety of hard to reach locations, such as indoors and underground, meaning that existing communications networks have struggled to maintain connectivity with all meters. The meter success rate is low, data transmissions are so far unstable and power consumption is too high. Against this background, Shenzhen Gas, China Telecom, Huawei, and Goldcard have jointly trialed NB-IoT gas meters to try and solve some of the challenges that the industry faces with today’s smart gas meters.

British Gas Modernizes its Operations with Innovative Smart Metering Deployment
The UK government has mandated that smart meters are rolled out as standard across Great Britain by end of 2020, and this roll-out is estimated to create £14 billion in net benefits to the UK in consumer energy savings and lower energy generation demand, according to the Oxford Economics report, “The Value of Smart Metering to Great Britain.” While smart-metering systems have been deployed in many countries, the roll-out in Great Britain is unique because it is led by energy retailers, who have responsibility for the Electricity and Gas meters. The decision to have a retailer-led roll out was made by DECC (Department of Energy and Climate Change) to improve customer experience and drive consumer benefits. It has also led to some unique system-level requirements to support the unique local regulatory model.
