STORAGE


DNV GL © 2018

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

residential

Aggregated utility

Arbitrage

Network support – voltage, thermal constraints support…

Smoothing and firming up non-firm generation

Ancillary services - frequency and reserve products from the TSO

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


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.
