STORAGE

Eight emerging dynamics for storage (1/2)
11
Costs declining rapidly for energy storage
Storage will be a key enabler to increase RES penetration
by smoothing variable resource on the grid and vice versa
As with PV, performance guarantees are one of the
main contributors to market maturation
+ Storage market widely seen as where solar market
was 5 years ago
PV started as cost-intensive technology … now becoming
competitive with conventional generation

Resilience: Electric power systems interdependence –
back up power – energy security
Stacked values: Storage deployments with solar PV can
provide income and cost benefits on both sides of meter
Regulatory requirements and financial incentives
emerging in several countries
Income opportunities for project developers deploying
combined technologies in otherwise declining “solar only”
markets – self consumption
Emotional appeal: Customer demand for more energy
independence – new product/appliance and services
(the “Tesla effect”)

Ideal market characteristics for storage
13
High penetration of
renewables
Weak electrical networks
and networks requiring
upgrades
System flexibility required
to align supply and
demand
Off-grid systems
High usage of peaking
diesel generators
Driving efficiency in renewables and gas
peaking plants
Policy and Regulation

Where? Across the energy network value chain
14
Bulk storage >50 MW Utility scale
100 kW-10 MW
Generation Transmission
Distribution
Commercial,
industrial &
residential
Aggregated utility
scale 2-50 MW Customer-led storage (behind the meter)
<10MW
Arbitrage
Synthetic inertia
Load shifting
Network support – voltage, thermal constraints support…
Smoothing and firming up non-firm generation
Ancillary services - frequency and reserve products from the TSO
Outage mitigation

DNV GL experience from existing markets
15
Regulatory framework must be clear.
Is the storage market bankable for the services it can provide?
In a few places solar+storage is a better investment than solar alone.
Storage is already economic ‘behind the meter’, especially for large industrial
and commercial customers.

“ IMPRESS ” PROJECT
ees & IBESA Summit France, Strasbourg, 24 Oct 2018
DNV GL © 2018
“ IMPRESS ” Integrated Monitoring and Performance Reporting of Energy Storage Systems
Current situation of storage monitoring solutions:
System suppliers provide energy storage systems including status monitoring
Vendor monitoring data is the basis for warranty and potential conflict
No simple insight into the interaction between solar-PV system and storage system
No quick overview of performance of multiple storage systems from different suppliers
IMPRESS offers:
Independent, cloud-based platform that provides performance reporting and predictive analysis
Direct, simple insight into and graphical presentation of system performance
Seamless integration and monitoring of interaction between renewables and storage
Reliable independent data acquisition essential for resolving conflict on the performance with a vendor
17
IMPRESS could be an international standard for energy storage system monitoring and analytics

Technical monitoring platform – Integration options
Data retrieval directly between local SCADA
and central servers over the internet.
The data connection can be between the
on-site local SCADA servers or the
centralized database of the local SCADA
provider through the cloud.
Specific hardware will be physically
connected on-site to the local SCADA
system and will collect, store, normalize
and map every data item before
transmitting the information to the central
system.
