Micro-Combined Heat & Power Generation Part 1 | Micro-cogeneration Technology Gian Maria Rossi Sebastiano Managing Director g.rossisebastiano@totem.energy TOTEM ENERGY A SUBSIDIARY OF ASJA GROUP With a strong expertise in centralized energy generation Asja Group decided years ago to move into the business of decentralized energy generation with a strong awareness it will play an renewable energy since 1995 165 MW installed power essential role in the years ahead. Through the daugther company TOTEM ENERGY, Asja Group has become a specialist in Onsite Energy Generation products and particularly in Micro Combined Heat and Power generation. Its flagship product is the TOTEM micro CHP. 2 Our energy environment is changing rapidly as Governments globally strive to make cost-efficient use of resources while enabling the emergence of a low carbon economy. Innovative policy is crucial to enabling the emergence of those technologies that will deliver this outcome. Micro Combined Heat and Power (𝜇𝜇CHP), a cost-effective and flexible low carbon solution that generates heat and electricity on-site, can support the transformation of the energy system and the achievement of relevant policy objectives, including environmental ones. Widespread 𝜇𝜇CHP deployment can transfer a significant part of electricity generation at local level, creating significant benefits for the energy system and for consumers.

If you cover the residential heat requirement (with exception of the single-family building) with TOTEM microcogenerators, in Italy, according to the Althesys study, 30,000 premature deaths per year due to atmospheric pollution would be avoided. * NOx is one of the most dangerous atmospheric pollutants for human health because they are the precursors to form other harmful substances (mainly PM). 18 TOTEM FULL-THERMAL Heat & cool at the best efficiency TOTEM Full-Thermal heats and cools taking benefit of the natural gas low cost as well as the heat pumps high efficiency. As a result, this system is extremely advantageous from the economic point of view compared to the use of «stand alone» electric heat pump. 19 INTEGRATION OF THE 𝜇𝜇CHP WITH THE HEAT PUMP The change in the Building Regulations by the end of the decade that will require any replacement of heating system to achieve a carbon reduction improvement vs. condensing boilers has the potential to establish a vibrant low carbon heating market. Such change would generate a level playing field for low carbon heating products, including 𝜇𝜇CHP . The power generated by the 𝜇𝜇CHP can be used by a Heat Pump to produce additional heat or to operate as a chiller. The combination of 𝜇𝜇CHP + Heat Pump can serve as a simple means of readily upgrading the existing stock of residential gas boilers and can integrate with legacy high-temperature heating systems (e.g. radiators, pumps) The global efficiency of the 𝜇𝜇CHP + Heat Pump systems can be as high as 160%: 100 energy units of natural gas become 160 units of heat to the end user 20 TOTEM DISTRICT TOTEM clusters distributed over the territory make energy platform efficient, flexible and with low emissions. District heating & cooling To meet local users’ thermal needs (heating and cooling) by creating forms of «smart» district heating at the urban district level. Digitized smart grid To meet local power requirements by increasing the flexibility of renewable energy plants and optimizing the operation of the power grid through the access to the Dispatching Services Market(MSD). Thanks to the intelligent TOTEM Operation System that makes energy platforms flexible and helps to control it quickly. 21 • 𝜇𝜇CHP DISTRICT POWER & HEATING Aside from an ideal like-for-like heating replacement in individual properties, 𝜇𝜇CHP is well placed to operate in a modular fashion in a shared environment, benefiting from economies of scale. 𝜇𝜇CHP is an ideal solution for social housing or for a block of flats and community heating schemes. • The modular deployment of 𝜇𝜇CHP may become the predominant commercialisation means as the decarbonisation targets become more stringent. • Distributed 𝜇𝜇CHP clusters can jointly make a low emission District Power and Heating. • In fact, 𝜇𝜇CHP can meet with flexibility the distributed customer demand of heat & power with emissions 9 times lower than the boilers with Heat Power the lowest emissions and 20% less CO2 over centralized electricity generation. 22 𝜇𝜇CHP SMART GRID INTEGRATION With the deployment of smart meters and the smart grid coupled with improvements in energy storage, 𝜇𝜇CHP flexibility would generate innovative possibilities to incorporate the demand side more actively in power system operation (prosumers) with considerable benefits. 23 TOWARDS ENERGY 4D TOTEM combined with renewable sources (heat pump and PV) 24 𝜇𝜇CHP BENEFITS FOR THE USER Economic benefits savings on energy bills Enabler for District Power and Heating Increased security in electrical supply (𝜇𝜇CHP can also work in "island" mode in the event of blackouts) Operation in "Peak-shaving" to cope with high power demand for limited time periods Increased "Power quality" to ensure constant voltage and frequency to safeguard production processes 25 𝜇𝜇CHP BENEFITS FOR THE ELECTRICAL SYSTEM AND FOR THE COUNTRY Widespread 𝜇𝜇CHP uptake could complement significant investment in centralised generation, or indeed transfer a considerable proportion of electricity generation from big centralised power stations to the local level About 7% of all generated electricity is lost when it is transported to consumers as a result of transmission and distribution losses. 𝜇𝜇CHP penetration would allow the efficient generation of electricity by alleviating losses of electricity In an environment that favours a more important role for local energy generation, 𝜇𝜇CHP is the most controllable distributed energy technology. The power output of 𝜇𝜇CHP can allow enhanced viability in local power generation as a result of its flexibility and natural fit with key renewable solutions and domestic electricity demand 26 𝜇𝜇CHP BENEFITS FOR THE ELECTRICAL SYSTEM AND FOR THE COUNTRY Benefits for the balance of payments and decreased dependence on import of fossil fuels Reduced CO2 and NOx emissions (reduced dead and health costs) Decreased occurrence of overload conditions in the transmission lines, with increased resilience of the electric grid Reduced transmission and distribution losses Encouragement of new energy providers liberalization of the energy sector 27 Micro-Combined Heat & Power Generation Part 2 | Applications and Markets Gian Maria Rossi Sebastiano Managiing Director g.rossisebastiano@totem.energy APPLICATIONS TOTEM users Wellness centers swimming pools, thermal baths, spa Tourist accommodations hotel, resort Healthcare hospitals, polyclinics, nursing homes Residential condominiums Public schools, public buildings Agricultural sector dairies, sausage factories Distribution supermarkets, outlet Small/medium industry production sites Energy districts micro grids for district heating and power generation Utilities 29 APPLICATIONS IN ITALY Industry 9% Hotel 33% Residential 6% Swimming Pool 30% Healthcare 22% 30 𝜇𝜇CHP POWER DEMAND COVERAGE EXAMPLE: SWIMMING POOL 30.000 Consumo energia… Power Demand Generated Power Energia elettrica… 25.000 20.000 15.000 10.000 To achieve the maximum economical benefit 𝜇𝜇CHP covers the baseload (maximum operation hours) 5.000 0 gen feb mar apr mag giu lug ago set ott nov dic 31 BUSINESS CASE SWIMMING POOL | ECONOMIC BENEFITS Cost without TOTEM Heat (methane) Power Total (A) 15.684 € 43.442 € 59.126 € Cost with TOTEM (1 x 25 kW) Methane and TOTEM operation Power Total (B) 27.253 € 14.560 € 41.813 € Incentives to use TOTEM Tax deduction (C) Annual gross savings (A-B+C) Cumulative gross savings in 15 years 4.290 € 21.603 € 324.045 € Cost for TOTEM (with installation) 64.800 € Cumulative net savings in 15 years 259.245 € Payback (years) * 3,0 With reference to energy prices applicable to Italy.
