1 How to tackle air pollution
What is your proposal? Tangent Energy's site energy storage systems automatically manages available power sources such as diesel generators, PV, wind, or the grid and stores the electricity in a battery which it dispatches in a controllable manner. The result is a typical site generator is switched off for over 60% of the week. The system also provides air pollution monitoring to report on CO2, NOx, PM, fuel and energy consumption.   What does it do? The system powers the site from its batteries. When the batteries are low the system automatically runs the diesel generator to recharge itself. The loads are prioritized and selectively switched on and off to achieve the most efficient load profile. All the data is visible in the web platform. How does it meet the challenge? The purpose of the system is to reduce emissions from burning fossil fuels. It provides users with the means to make immediate change and it presents the data showing the underlying issues which gives users evidence to support making further changes and developing a better energy strategy by using appropriately sized appliances and reducing generator sizes to appropriate levels. Reporting and comparing air pollution at every site identifies the range between best and worst cases and focusses attention to where improvements are needed. The system provides a cost-effective energy technology strategy and roadmap towards a zero-carbon future.   USING SMART MICROGRIDS TO REDUCE EMISSIONS

2 UK - 40,000 people per annum die due of the effects of air pollution
Costs the NHS £20 Billion pa

3 10% of CO2 emissions from Construction
7% of NOx and 14% PM2.5 emissions Central London the average levels are almost double the WHO limit We’re being driven by changes in technology, Markets, environmental concerns, legislation, Consumer demands and all the while we have to deliver sound business. If we infuse our companies with a culture that respects people, inside and out that demonstrates how our values are relevant, then we have a vastly improved our ability to carry on our business. If we don’t then someone will There are NO safe limits for PM2.5 Construction and Sustainable Development’ Plain English, Constructing Excellence, Section 2, Page 5, 01/01/08

4 The problem with Diesel
Sized for the worst case Can’t cope with Peak loads Rarely if ever runs at prime rating Bad for the generator Produce CO2 and dangerous levels of Air pollution 10 x

5 HOW ARE FUEL SAVINGS ACHIEVED?
Tier V engines can’t tolerate low loads

6 HOW ARE FUEL SAVINGS ACHIEVED?
Optimum 60-70% load Average <20% load Tier V engines can’t tolerate low loads

8 MICROGRIDS The proposition

9 Microgrid – stage 1 40% Reduction in runtime AUTO START STOP EMS
Add Other power sources Building Energy Management System manages the loads Manage the power sources Manage the loads Report and analyse Sweat the asset Manage the fleet Connected to the power source(s) PV – assuming you have enough space to be meaningful Grid Genset Prioritise which source to use first Recharge the batteries using the cheapest source Control the dispatch Prioritise the loads, time, Power and Energy Collect the data

10 Microgrid – stage 2 60% Reduction in runtime BEMS AUTO START STOP EMS

12 99% Microgrid – stage 4 60% Reduction in runtime Air Quality
Diesel is simple but deadly Microgrids are a cost effective solution that bring together renewables, grid, storage, energy management, the internet to create a highly efficient alternative Microgrids provide a means to exercise greater intelligence Reduce diesel runtimes Reduces noise Reduces toxic air pollution Monitors Air pollution levels Reduce CO2 emissions Improves site health and safety Increases usage of renewables Amplifies the capacity of the grid Supports Electric vehicle charging Provides monitoring and reporting, increases accuracy and reduces overhead Provides fleet wide view of performance Enables the implementation of an energy strategy that can be measured and developed Changes the status quo, changes behaviours Air Quality Monitoring

13 Fleet wide view Compare Best site Worst site Greatest change
Total Emissions Total Savings Monitor Report Fleet wide data Compare best case to worst case sites Identify the causes Implement change Measure the air pollution Change the runtimes, change the equipment Prove the changes are working Report to stakeholders Support site EV transition Single reporting point See what the generators are doing Optimise the loads, phase balancing Optimise the appliances Segregate and control the circuits Remote monitoring, in real time Use the results to make better decision on the next site

14 TAKE CHARGE of the situation and do something better
The Result Reduce POLLUTION to an absolute minimum: quickly, cost effectively and reliably Increased UNDERSTANDING and AWARENESS CONTINUOUS IMPROVEMENT through fact based decision making PROVE its working, that the energy management strategy is working and developing Support ongoing operations without interruption, increase RESILIENCE TAKE CHARGE of the situation and do something better

15 Microgrid Take Charge The infrastructure to supply electricity without the utility grid: Off grid or edge of grid There is no Grid The grid is there but unreliable or its expensive
