Net Employment Benefits from
Onshore Wind in 2020
SEAI / IEA Wind RD&D Seminar
26th May 2014
Sarah Stanley ESRI/SEAI Fellow, Economic Modelling Department, SEAI
Introduction
• Multiple Motivations for Wind Deployment:
- Displacement of fossil fuel emissions, diversify energy
portfolio, target compliance
• SEAI’s Sustainable Energy Investment Model (SEIM) – Net
Macroeconomic and Employment Impacts from Onshore
Wind in 2020.
• Presentation Outline:
- Modelling Methodology
- NREAP/NEEAP 2020 Scenario Assumptions
- Preliminary Results
- Future Analysis
Introduction to the Sustainable
Energy Investment Model (SEIM)
• SEIM based on REMI. Widely applied in the US.
Combines I-O and econometric methodology.
• Core function is Impact Analysis (not forecasting).
• Insights into how investment in renewable energy
can affect employment, output, and expenditure.
• Net Impact Analysis rather than Gross.

Electricity Generated by Wind Baseline and NREAP/NEEAP Scenario
. BASELINE NREAP Additional
Assumptions in the Baseline -
What if we don’t invest in wind?
• SEIM Baseline: electricity supply grows at a rate relative to overall
growth (~2% per year). In line with SEAI Energy Forecast.
• With increased wind deployment, no displacement of fossil fuel
generation capacity imposed in the baseline:
- Wind displaces running costs for conventional plants (via cost of
imported fossil fuels, ~ €177ml in 2012, SEAI).
- Capacity payments provide lost revenue for generators for
continued operation. Little loss of plant employment.
- Displacement in the transport and storage of fossil fuels imposed.
• Capital investment in wind:
→ Demand increases, primarily for the construction of wind farms.
→ Higher demand generates employment
→ Employment stimulates higher disposable income and consumption, as well as changing optimal capital stock.
→ In price block, employment feeds into a change in employment opportunities, compensation, production costs, and prices
Structure of the Model
• Model Blocks and Linkages:
A change in one input will create a reactionary change in all other endogenous areas of the economy

Electricity Supply Net Employment
• 0.6 net jobs per MW in domestic electricity supply
services (0.4 direct, 0.2 indirect and induced)
• Long term direct employment with structural
importance for Ireland.
• 0.08 net jobs per MW in repairs
• Opportunity to capitalise on new
growth sector in wind energy and
develop indigenous expertise in
wind management.
Construction of Wind and
Transmission Grid Net Employment • Construction employment gradually increases up to 2020.
• Approx 2.7 net construction jobs per MW (in job-years) in entire economy
in 2020 (1.8 direct, 0.2 indirect and 0.7 investment induced)
• Short term boost to Irish construction sector
• Evenly dispersed between BMW and S&E
• 0.07 professional services jobs
per MW (engineering, legal, etc.)
• 0.05 finance jobs per MW
(both ~50% import intensity)
• 0.04 less jobs per MW in transport
and storage of fossil fuels
Manufacturing Net Employment
• 0.2 net Irish jobs per MW in manufacturing (0.14 indirect,
0.06 induced) assuming a 66% import intensity.
• Ireland is well placed to capture 22% of investment in wind
manufacturing (foundations, controls and instrumentation).
• Other manufacturing activities require scale/policy incentives

Findings, Other Factors &
Future Analysis
• In addition to environmental and security of supply benefits,
wind deployment has positive impact on GDP & Net
Employment
Other Factors
• Omits impacts on amenity value, housing prices, tourism.
• Similarly ignores ancillary benefits:
- supply chain development, target penalty cost, security of
supply, avoided environmental costs.
Future Analysis
• Comparison between various forms of RE investment
• Further electricity price sensitivities
• Post 2020 capacity projections and impacts on employment,
taking into account projected future investment and duration
of feed-in tariffs.
