This webinar discussed fuel cell backup power solutions that were successfully used during Hurricane Sandy. It began with an overview of the importance of backup power for network resilience from Kyla Reid of the GSMA. The webinar then featured a case study from Lennox McCartney of Precision Power and Air Bahamas on their experience deploying Ballard fuel cell generators for Bahamas Telecommunications Company during Hurricane Sandy. The fuel cells provided over 700 hours of backup power across 17 sites and prevented a potential 50% loss of cell service. Based on this successful experience, BTC is now installing an additional 16 fuel cell backup systems.

Impact of Distributed Generation on Energy LossNadineCroes
The aim is to give more insight into the effect of distributed power generation on energy loss. In most cases these distributed generators (DGs) are based on renewable energy such as solar panels and wind turbines, but there are also new technologies to increase efficiency such as the micro combined heat and power systems. Distributed generation can increase efficiency in the grid by reducing the distance between generators and consumers of electricity. The objective is to find an optimal mix of distributed generators (DGs) in a district so that energy loss is minimized and overload is avoided. The effect of using future electronic devices, such as electric vehicles, is also studied. To find an optimal mix of DGs a mixed integer quadratic programming model is defined and a case study is presented. The results indicate that the optimal solutions give substantial reductions in loss without overloading the system.

Community Microgrids: A resilient clean energy solution for citiesClean Coalition
From 2017 to 2018, the U.S. experienced 30 weather- and climate-related events that cost $1 billion or more and collectively caused damage totaling a record-breaking $404 billion, not including the loss of human life. The Clean Coalition is staging Community Microgrids to provide resilience in the face of these disasters. Municipalities and their constituents are interested in building resilient communities, and Community Microgrids provide a solution that combines solar generation with energy storage and other distributed energy resources (DER) to provide indefinite renewables-driven backup power for critical loads. Many public agencies are taking a serious look at solar+storage to offset increasing utility costs, and to help achieve their climate goals. Adding microgrid-specific equipment like switches and monitoring, communications, and control equipment allows critical facilities to island during grid outages, providing business continuity and resilience with renewables-driven backup power.
Simon Gamble, Manager for Hybrid Off-Grid Solutions at Hyrdo Tasmania, presented at our seminar entitled 'Securing Australia's Energy Future: The Challenge' on Friday 15 August 2014 in Melbourne.
Held as part of our Sustainability Leadership Series, the seminar brought together experts and practitioners from across government, business, academia and civil society, to discuss Australia’s transition to a secure, cleaner and cost-competitive energy future.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

ERIC: Now let’s get started… As you know, the Canadian Hydrogen and Fuel Cell Association is sponsoring this webinar on what we believe to be a very timely and important topic. As we see more and more areas of the world effected by increasing numbers of natural disasters, the need for reliable backup power will only increase. Our first presenter today is Kyla Reid, Head of the GSMA Disaster Response Programme. As Head of the Disaster Response Programme, Kyla is responsible for leading the mobile industry in improving resilience and engaging in coordination initiatives that most effectively support citizens and humanitarian organizations on the ground following a crisis. Kyla will discuss backup power as a core component for network resilience in disaster situations from the perspective of the GSMA and the work the Disaster Response Programme is doing. Following Kyla, Lennox McCartney, President of Precision Power and Air Bahamas will be our next presenter. Lennox will discuss fuel cell power generation systems as a means of reliable, extended duration backup power and how the fuel cell systems installed in the Bahamas during Hurricane Sandy kept the network up and running when people needed it most. We will then open up the session to answer questions that have been submitted in text form during the webinar. So with that, I will now turn the floor over to Kyla Reid of the GSMA Disaster Response Programme…
KYLA: Thank you Eric… Spend a few minutes to provide some context on why we at the GSMA believe global networks are increasingly important Discuss the role of backup power in providing network resilience
Speaking points Global trade association for mobile industry Here’s a snapshot of the GSMA’s reach around the world. In addition to our 800+ mobile operator members, our associate members include handset makers, software companies, equipment providers, internet companies, and media and entertainment organizations. The role of the GSMA is extremely important in this context, as we are uniquely able to coordinate a collective response to the challenges faced by our members, and to engage productively with national regulatory authorities as well as policymakers. Our work as the mobile industry association can be divided into four broad areas : a forum for industry, a market think tank, an advocate for the industry, and bringing the wider mobile ecosystem together at Mobile World Congress, Mobile Asia Expo and other conferences and events. Mobile for development – focus on providing services to populations living in emerging and developing markets
A brief intro to the GSMA DR programme why it came about what some of the over arching challenges facing MNOs are in crisis (including infrastructure/technical/power) how we work with the industry to address them
Context: disasters increasingly a reality of life around the world- increasing in frequency and magnitude, trends suggest this will continue. Often most vulnerable are most badly affected. New strategies being developed across the disaster response cycle, and many of these rely on new technology, including mobile Stats on mobile penetration/growth, - this means that increasingly, those impacted by disasters can access information, call for help, reconnect with their loved ones. One of the first thing that people grab in a disaster is their mobile phone- but for this technology to be a life saving tool, the network on which it runs must be resilience, robust and able to cope with the infrastructural, human resource, network management and coordination challenges that these situations present. Critical to the health of the mobile network in these types of scenarios is redundancy, autonomy and back up power.
Mobile networks increasingly depended upon and under pressure to perform as mobile is seen as a basic tool and connectivity as a basic need in humanitarian situations Examples from Hurricane Sandy, Japan triple-disaster, Argentina, Chile, Philippines- Humanitarian sector acknowledging dependence on mobile networks Communication increasingly being viewed as core part of aid and assistance
Power a key problem for mobile operators Interdependence with commercial power providers which are often impacted in large scale disasters Difficulties experienced in accessing fuel (not only quantities, but prioritisation of mobile network vis-à-vis other sectors, logistical and transport difficulties involved in getting fuel) Challenges with existing generators- location, land lord access issues, redundancy, vulnerability Regulations around length of autonomy vary, one hour redundancy? 24 hour redundancy? Cost vs impact, and anticipating natural disaster risk – need for long term sustainable solutions
Case studies: Japan, Haiti, New Zealand, Sandy, Chile, Argentina flooding- power failure was key in all experiences- Need for innovation solutions, new strategies, new technology, new partnerships to address this challenge - FCC Post-Sandy Field Hearings highlighted the challenges presented by power failure, including licensing issues with fuel providers, security (generators being stolen), transport of fuel across state boundaries and communications with commercial power providers
Disaster Response Programme born out of belief that when you restore the mobile network, you rebuild the human network Backup power core part of network preparedness and restoration Thank you ERIC: Thank you Kyla. Your presentation certainly highlights why communication networks are so important during crisis situations and the how power supply is one of the most critical components. Now let’s turn the floor over to Lennox McCartney of Precision Power and Air Bahamas…
Thank you Eric… Presentation will share experience with fuel cell generators in the Bahamas with the primary telecommunications supplier Focus on extreme weather situation during Hurricane Sandy
Primarily providing power protection and power continuity solutions Establishment of PP&A Bahamas in 2011 Responsibility of deploying fuel cell generators in the Bahamas
Geography of Bahamas to give presentation more context Island state 21 major populated islands Nassau capital and most populated island
Backup power provided using batteries, diesel generators and fuel cell generators Great need for remote servicing
Go through some challenges Most of mobile locations have batteries as primary backup Highlight challenges of batteries Highlight challenges of diesel gensets – example of reliability and pilferage issues
Reason for selection primarily reliability Extended runtime Easy to refuel – easily portable fuel; good for emergency situations Easy maintenance Cost effective
Nassau has largest population (250K out of 350K – 70%), although one of the smallest islands Initial deployment were at mobile /wireless locations Planned site and mostly wire locations. These locations have similar characteristics as the mobile locations. All Sites have commercial power with the primary backup power is batteries. Fuel Cell Generators provide long run backup power support
Abaco Island and Grand Bahama Islands are 20 to 30 min plane rides away from Nassau. Daily ferry service to/from islands from Nassau\\ BTC concentrated deployment efforts on higher populated areas
Typical operational experience – daily/monthly basis 4 – 5 hours runtime per month Extensive remote monitoring – able to do maintenance without site going offline
Look at experience in extreme weather conditions Not a major hurricane for the Bahamas – not a direct hit Affected Nassau, Abaco and Grand Bahama – Abaco and Grand Bahama mostly
Impact summary Commercial power outages lasted up to 3 days in some scenarios Damage to electrical infrastructure at base station sites caused power failures in excess of 5 days in some areas Nassau power outages lasted 24 – 48 hours
Runtime during hurricane sandy Showing spreadsheet of runtime of installed systems Some sites commercial power remained on throughout the hurricane Nassau – lower runtime for most units End of 48 hours most sites had power restored Long runtimes due to fact that after commercial power restored, damage to electrical infrastructure at the base station sites caused delay in getting powering Fuel cells maintained power – aware of situation through remote monitoring All systems that were needed ran as they were supposed to
Summary of overall operational experience during Hurricane Sandy
Fuel cell generator summary – highlights of performance in Hurricane Sandy Systems proved 100% reliable Future BTC deployment Thank you very much and I’ll be happy to answer any questions
ERIC: Thank you Lennox, that was a very informative presentation with some very helpful insights. You provided a lot of very detailed information both from an operational and a general perspective on the situation during Hurricane Sandy. At this time we would like to address questions that we have received during the webinar. As a reminder, please send your questions in by using the question box located at the bottom of the control panel on your screen. We will try to answer as many as time will allow. If we don’t get to your question, then an appropriate individual will respond to you following the webinar. Q&A’s ERIC TO READ QUESTIONS, THEN HAND-OFF Questions from control panel to be sent to core team by Julia & Guy If we need them, will have pre-planned questions available Pre-planned questions (if needed): Questions for Eric: This webinar focuses on one specific fuel cell system deployment for telecom backup power – are you seeing interest in this application as a general trend in the industry? Are there particular regions where you’re seeing telecom deployments? … where fuel cell applications are particularly well suited for telecom? Questions for Kyla: Do you see telecom operators addressing this issue independently or does there need to be regulations in place around backup power? Does GSMA see this happening in the short- or medium-term in specific jurisdictions? Are any jurisdictions dealing particularly well with this issue today? Questions for Lennox: How did the fuel cell systems’ performance differ from other backup power solutions in previous hurricane situations? Can you outline the main differences between fuel cell systems and diesel generators? … and battery solutions? How does the installation process differ for a fuel cell generator as compared to a diesel generator? …what challenges do fuel cell installations present?
