在全国范围内，公用事业公司、州监管机构和政策制定者正在考虑许多潜在的解决方案和战略来管理不断发展的电网和能源行业。从环境保护署 (EPA) 的清洁能源计划法规等政策措施，到总统的第一次四年期能源审查，再到基础设施现代化工作，公用事业公司和州监管机构正处于紧张推进和审查的时期。在这些措施中，EPA 的清洁能源计划尤为重要。它旨在减少现有化石燃料发电厂的二氧化碳排放量。根据《清洁空气法》第 111(d) 条的规定，EPA 于 2015 年 8 月发布了最终法规，要求各州制定并提交州计划以实现联邦减排目标。清洁能源计划还培养了州/联邦合作的精神，敦促各州相互合作，并与 EPA 共同制定最佳减排结构。尽管 EPA 提议的计划的合法性存在争议，但公用事业和监管机构已经在分析各种应对措施的成本和收益，包括燃煤电厂转换、可再生能源投资、能源效率计划等。
American Electric Power (AEP) 总部位于俄亥俄州哥伦布市，是美国最大的电力公司之一，为 11 个州的 500 万客户提供服务。除了 530 万客户外，他们还运营超过 38,000 英里的铁路
AEP 将 Utilidata 的 VVO 解决方案 AdaptiVolt™ 部署在来自俄亥俄州 Gahanna 的一个变电站的 6 条 13.8 kV 馈线上。使用 RF 网状遥测网络，AdaptiVolt™ 与八个线路电压监视器（部署在配电系统的初级上）、十五个基于现场的开关电容器组、两组中线电压调节器和六组三个单相电压调节器进行通信在变电站。 AdaptiVolt™ 根据从所有现场设备收集的数据中提取的信息，对电压调节器和电容器组进行协调控制。 AdaptiVolt™ 系统的可见性和控制通过其配电管理系统用户界面提供给 AEP 系统操作员。从 2012 年开始的一年时间里，AEP 和 Utilidata 对其在俄亥俄州 Gahanna 的试点项目进行了广泛的 M&V 测试，以验证 AdaptiVolt™ VVO 解决方案的节能和降压效果。

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.
OneWireless Enabled Performance Guarantee Test
Tata Power's power generation equipment OEMs (M/s BHEL) is required to provide all of the instrumentation and measurement devices for conducting performance guarantee and performance evaluation tests. M/s BHEL faced a number of specific challenges in conducting PG tests: employing high-accuracy digital communications for instrumentation, shortening setup and dismantling time, reducing hardware required, making portable instrument setup, avoiding temporary cabling work and the material waste costs
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.
