The old utility world

Central production

One waytransmission to

customers

Load control bysome simple

communication

means



The old utility world

Monopoly

Average selling price covers investment independent of

usefulness and risks

Production was close to federal and regional governments (or was

owned by the government)



Next step: Market liberalization

Stock market for electricity: Investment in new

production capacity becomes riskier.

Transmission lines as bottleneck



The future

Customers added value:

Producer

Storage provider

Increase in energy demand

Dispatchable loads also for residential

houses



Example New York

The following 2 slides are from the PVPS Workshop

Electricity Systems of the Future held in Golden, Colorado 21st April 2015, Author Lena Hansen, Rocky mountain institute

The state of New York set up working

groups to design the future of the

electricity and energy services:

Reforming the energy vision REV.



REV Regulatory Policy Order

Utilities, and this Commission, could respond to [the challenges facing the industry] by clinging to the traditional business model for as long as

possible, relying on protective tariffs, regulatory delay, and other

defenses against innovation.

Example New York

Alternatively, we can identify and build regulatory, utility, and

market models that create new value for consumers and support

market entrants and this new form of intermodal competitionin other words, embrace the changes that are shaking the

traditional system and turn them to New Yorks economic and environmental advantage.

We decisively take the latter approach.



Press comment:

In one of the most promising moves in the energy sector in years, New York State is

proposing a way to get a head start on, and

perhaps help lead, a revolution in the world

of electricity generation

May 12th, 2014



Threads for utilities



Grid defection

With lower costs for

PV and storage, the

grid can become

optional in certain

areas of this world

Average electricity

price in Hawaii:

35 47 UScents/kWh



Opportunities: Swiss case

Average electricity consumption of a household:

4000 6000 kWh/a

Grid connection:3 phase 400 V, 25 or 40 A

-> 17 to 27 kW



Change of heating system

Before:1500 Liters of Oil

New:5000 kWh/a of

electricity



New PV System

7 kWp

7000 kWh/year

70% in Summer



New mobility standards

15 000 km/a

20 kWh/100km

3000 kWh/a for 1 Tesla

(+ 100 kWh/a for an E-Bike)



The future Prosumer

Before: 5000 kWh/a

Heat Pump: +5000 kWh/a

PV System: - 7000 kWh/a

EV (Tesla): + 3000 kWh/a

Total: 6000 kWh/a from Grid

Self consumption of PV: max. 5000 kWh/a



The new utility/DSO

Service provider for prosumers:

Installer for PV systems

Extended metering services (Smart Meters/load management)

Managing the electricity flow at their customers premises

Maintaining the PV systems



The are many more

opportunities in the new

electricity markets
