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
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.

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 (CHP),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 CHP deployment can transfer a significant part of electricity generation at
local level, creating significant benefits for the energy system and for consumers.

Engine-based CHP are flexible in terms of fuel type utilisation.
Therefore, renewable gases like biomethane should be considered as the eventual fuel of
preference for CHP.
Renewable gas fuelled CHP would allow the technology to become part of the portfolio
of renewable solutions to attain full decarbonisation of power and heating.

TOTEM microcogenerator
Innovative, 100% Italian, the evolution of the first
microcogenerator in the world designed by Fiat Research
and Development Center in 1977. TOTEM can be
considered as a «boiler» that produces power in addition
to the heat without harming the environment.

How does it work
The TOTEM brain is its Operating System that, thanks to
the application of IoT technology, allows to manage
every single unit remotely and also to enable cluster
operation.
The TOTEM heart is a natural gas engine of FIAT 500
coupled with the alternator for power production.
Thanks to an efficient system utilizing a heat exchanger,
the engine exhaust heat is totally recovered and provided
to the customer.
TOTEM, WHY IT IS CONVENIENT

1 data from the ISPRA report 262/2017
2 limits in Lombardia region for “Rehabilitation zones”
3quota attributed to the thermal energy; total emissions: ≤ 10 mg/Nm3
The TOTEM is the most efficient microcogenerator with
the lowest emissions into the atmosphere thanks to the
stoichiometric control of the carburation and to an
efficient catalyst.
NOx emissions (nitrogen oxides) of TOTEM are:
25 times lower than the set limits established for
boilers in the region of Lombardia, that are the
stringent at national level
9 times lower than the boilers with the lowest
emissions (class 5)
NOx is one of the most dangerous atmospheric pollutants
for human health because they are the precursors to
form other harmful substances (mainly PM).

Microcogenerators can replace boilers in all cases
where there is demand for electricity and heat
(residential, tourist accommodations, wellness centers,
healthcare, schools, public buildings, small/medium
industry, Distribution,….).
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.

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.
TOTEM FULL-THERMAL
19
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
CHP .
The power generated by the CHP can be used by a Heat Pump to produce additional heat or
to operate as a chiller.
The combination of CHP + 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 CHP + Heat Pump systems
can be as high as 160%:
100 energy units of natural gas become 160 units of
heat to the end user

TOTEM DISTRICT
TOTEM clusters distributed over the territory make
energy platform efficient, flexible and with low emissions.
District heating & cooling
To meet local usersthermal 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
Heat Power
Distributed CHP clusters can jointly make a low
emission District Power and Heating.
In fact,CHP can meet with flexibility the
distributed customer demand of heat & power
with emissions 9 times lower than the boilers with
the lowest emissions and 20% less CO2 over
centralized electricity generation.
Aside from an ideal like-for-like heating replacement in individual properties, CHP is well
placed to operate in a modular fashion in a shared environment, benefiting from
economies of scale. CHP is an ideal solution for social housing or for a block of flats and
community heating schemes.
The modular deployment of CHP may become the predominant commercialisation means
as the decarbonisation targets become more stringent.
CHP DISTRICT POWER & HEATING

With the deployment of smart meters and the
smart grid coupled with improvements in
energy storage, CHP flexibility would
generate innovative possibilities to
incorporate the demand side more actively in
power system operation (prosumers) with
considerable benefits.

Economic benefits
savings on energy bills
Enabler for District Power and Heating
Increased security in electrical supply
(CHP 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
CHP BENEFITS FOR THE USER
25
Widespread CHP 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. CHP 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, CHP is
the most controllable distributed energy technology. The power output of CHP 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
CHP BENEFITS FOR THE ELECTRICAL
SYSTEM AND FOR THE COUNTRY
26
Benefits for the balance of payments
and decreased dependence on import of
fossil fuels
Reduced CO2and 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
