Alternative Procurement Scenarios

260. The core assessment set out above has been undertaken on the Baseline procurement scenario. The same approach has been undertaken to the enhanced scenario, as defined in the supporting Technical Impact Report (volume 3, appendix 18.1). This assumes an increased share of UK and Scottish content in the supply chain within the construction phase, so beneficial effects are greater.
261. The potential impacts of the Proposed Development on GVA in development, manufacturing and supply, and construction/installation activities under the Enhanced procurement scenario are set out in Table 18.50   Open ▸ .

Table 18.50: Potential Impacts (Enhanced Procurement Scenario) of the Proposed Development on GVA in Manufacturing, Construction, and Installation Activities – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Source: HJA analysis of BVG Associates (2021). Figures may not sum due to rounding.

262. Under the Enhanced scenario, there is some increase in the GVA impacts assessed at the Socio-Economics local study area level during construction phase. The quantitative assessment indicates some increases in the magnitude of impacts at this level. However, the changes in GVA impacts are not judged to be substantial enough to justify increasing the assessed significance of effects – also GVA impacts are already assessed as major beneficial for the majority of socio-economics local study areas under the Baseline scenario. Therefore no change in significance of effect is assessed at the socio-economics local study area level.
263. Under the Enhanced scenario, at the socio-economics local study area level the significance of effects assessed remain unchanged from the Baseline scenario as per Table 18.49   Open ▸ above.
264. There is a substantial increase in the GVA impacts assessed under the Enhanced scenario at the socio-economics national study area level during construction phase. The quantitative assessment indicates an increase from moderate to major (beneficial) to major (beneficial) magnitude of impacts at this level. The increase in GVA impacts are judged to be substantial enough to justify increasing the assessed significance of effects.
265. Therefore, under the Enhanced scenario, at the Socio-Economics national study area level the magnitude of the impact is deemed to be high (beneficial) and the sensitivity of the receptor is considered to be high. The effect will be of major beneficial significance, which is significant in EIA terms.

Secondary Mitigation and Residual Effect

266. The Applicant has committed to enhancement of beneficial effects as per section 18.9. No secondary mitigation is required.

Operation and Maintenance Phase

267. Potential expenditure on the following activities associated with the Proposed Development could support GVA in Scottish companies that are directly engaged in the operation and maintenance supply chain:

• wind turbine, balance of plant, and transmission maintenance and servicing; and
• vessel and crew activity.
  268. The operation and maintenance of the Proposed Development could also go on to support GVA indirectly in the wider supply chain.
  269. A 35 year operation period has been assumed throughout.
  270. The potential impacts of the Proposed Development on GVA in operation and maintenance activities at the socio-economics local study area and socio-economics national study area levels are set out in Table 18.51   Open ▸ .

Magnitude of Impact

271. GVA impacts have been assessed on the basis of direct, indirect, and induced impacts.
272. On the basis of a 35 year operation period, the impact is assessed as long term. Due to the contract-based nature of operation and maintenance activities, the impact is assessed as intermittent.
273. A comparison of the assessed impact compared to the relevant baseline conditions for each socio-economics local study area and the socio-economics national study area is set out in Table 18.52   Open ▸ .

Table 18.52: Comparison of Operation and Maintenance Phase GVA Impacts vs. Relevant Baseline Conditions – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Note: Assigned values from Table 18.23   Open ▸ shown in brackets.

Sensitivity of the Receptor

275. As per section 18.8, the sensitivity of the receptor for each socio-economics local study area and the socio-economics national study area is assessed as high – a summary is set out in Table 18.54   Open ▸ .

Table 18.55: Significance of Operation and Maintenance Phase GVA Impacts – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Secondary Mitigation and Residual Effect

277. The Applicant has committed to enhancement of beneficial effects as per section 18.9. No secondary mitigation required.

Decommissioning Phase

278. Potential expenditure on decommissioning of wind turbine and balance of plant associated with the Proposed Development could support GVA in activities associated with decommissioning in the socio-economics local study areas and socio-economics national study area.
279. The scale and duration of decommissioning activity is uncertain. The exact approach to decommissioning is not yet confirmed as best practice at the time is not currently known. It is anticipated that all structures above seabed level will be removed, but subject to review in the future on the basis of likely environmental impacts.
280. No plans are in place to consider potential locations for decommissioning support ports. It is not known if this will be located in Scotland. Given the need for large lay down areas the four ports identified as being under consideration for the construction phase would have the greatest potential to accommodate decommissioning activities based on current circumstances.
281. The Technical Report (volume 3, appendix 18.1) notes that activity associated with decommissioning of the offshore parts of the wind farm is likely to be supported in a similar way to installation and commissioning. However, the scale of activity will be reduced given the intention to leave cables in situ.
282. On this basis the magnitude of effects would be lower than those set out for the construction phase under the baseline and enhanced scenarios.
283. The significance of effects assessed at construction phase for GVA in manufacturing, construction, and installation activities are set out in Table 18.49   Open ▸ . On the basis of currently available evidence the significance of effects for the decommissioning phase will be no greater than moderate beneficial significance across socio-economics local study areas and the socio-economics national study area. This is significant in EIA terms.

Impact on Access to Employment Amongst Local Residents in Activities (Including Supply Chain) Associated with: Manufacturing, Construction and Installation; Operation and Maintenance; and Decommissioning

284. The expenditure in both local and national study areas will create a range of employment opportunity for residents within the respective areas. This will include supporting existing workforces within the supply chain as well as the creation of new roles where expansion of the sector is facilitated.
285. This impact is applicable to the construction, operation and maintenance, and decommissioning phases.

Magnitude – Assessment Approach

286. Magnitude of employment impacts are assessed against the following baseline conditions:

• economic activity (2019): using the economically active population as a benchmark to assess the scale of impact on the current available workforce; and
• economically inactive individuals that want a job and unemployed population (2019): comparison with this figure gives an indication of the scale of employment impacts in the context of potentially available workforce within an area.
  287. The criteria against which magnitude of employment impacts amongst local residents are assessed and can be found in Table 18.56   Open ▸ .

Table 18.56: Magnitude of employment impacts amongst local residents assessment criteria

Sensitivity – Assessment Approach

288. Sensitivity of employment impacts are assessed against the following baseline condition:

• policy environment: whether an area’s policy position has the aim of providing jobs, skills, education, and training for local residents to work in the offshore wind sector. Policy aims to provide the same opportunity in the renewable energy sector will also be considered as important. General policy aims to provide jobs, skills, education, and training for local residents in any sector will also be considered.

Construction Phase

289. Potential expenditure on the following activities associated with the Proposed Development could improve access to employment amongst local residents in activities (including supply chain) associated with development, manufacturing and supply, and construction/installation:

• wind turbine manufacturing and supply – blades, nacelle, hub, tower;
• balance of plant manufacturing and supply – foundations, inter-array cables, OSPs/Offshore convertor station platforms, offshore export cables; and
• construction and installation of wind turbine and balance of plant – wind turbine, foundation, inter-array cables, and other installation.
  290. The development, manufacturing and supply, and construction/installation of the Proposed Development could also go on to support access to employment amongst local residents indirectly in the wider Scottish supply chain.
  291. A maximum 96 month construction period has been assumed throughout.
  292. The potential impacts of the Proposed Development on access to employment amongst local residents in manufacturing, construction, and installation activities are set out in Table 18.57   Open ▸ .

Magnitude of Impact

293. Employment impacts have been assessed on the basis of direct, indirect, and induced impacts.
294. On the basis of a maximum 96 month construction period, the impact is assessed as long term. Due to the contract-based nature of manufacturing, construction, and installation activities, the impact is assessed as intermittent.
295. As discussed in section 18.3, impacts are considered across multiple socio-economics local study areas linked to the selection of construction ports, and the associated supply of a range of inputs and services.
296. A comparison of the assessed impact compared to the relevant baseline conditions for each socio-economics local study area and the socio-economics national study area is set out in Table 18.58   Open ▸ .

Alternative Procurement Scenarios

300. The core assessment set out above has been undertaken on the Baseline procurement scenario. The same approach has been undertaken to the Enhanced scenario, as defined in the supporting Technical Impact Report (volume 3, appendix 18.1). This assumes an increased share of UK and Scottish content in the supply chain within the construction phase, so beneficial effects are greater.
301. The potential impacts of the Proposed Development on access to employment amongst local residents in development, manufacturing and supply, and construction/installation activities under the Enhanced procurement scenario are set out in Table 18.62   Open ▸ .

302. Under the Enhanced scenario, there is some increase in the employment access impacts assessed at the Socio-Economics local study area level during construction phase. The quantitative assessment indicates some increases in the magnitude of impacts at this level. However, the changes in GVA impacts are not judged to be substantial enough to justify increasing the assessed significance of effects – no change in significance of effect is assessed at the socio-economics local study area level.
303. Therefore, under the Enhanced scenario, at the Socio-Economics local study area level the significance of effects assessed remain unchanged from the Baseline scenario as per Table 18.61   Open ▸ above.
304. There is a substantial increase in the employment impacts assessed under the Enhanced scenario at the socio-economics national study area level during construction phase. The quantitative assessment indicates an increase in the magnitude of impacts at this level. The increase in employment impacts are judged to be substantial enough to justify increasing the assessed significance of effects.
305. Therefore, under the Enhanced scenario, at the socio-economics national study area level the magnitude of the impact is deemed to be medium beneficial and the sensitivity of the receptor is considered to be high. The effect will be of moderate beneficial significance, which is significant in EIA terms.

Secondary Mitigation and Residual Effect

306. The Applicant has committed to enhancement of beneficial effects as per section 18.9. No secondary mitigation is required.

Operation and Maintenance Phase

307. Potential expenditure on the following activities associated with the Proposed Development could improve access to employment amongst local residents in activities associated with operation and maintenance supply chain:

• wind turbine, balance of plant, and transmission maintenance and servicing; and
• vessel and crew activity.
  308. The operation and maintenance of the Proposed Development could also go on to support access to employment amongst local residents indirectly in the wider Scottish supply chain.
  309. A 35 year operation period has been assumed throughout.
  310. The potential impacts of the Proposed Development on access to employment amongst local residents in operation and maintenance activities at the socio-economics local study area level are set out in Table 18.63   Open ▸ .

Magnitude of Impact

311. Employment impacts have been assessed on the basis of direct, indirect, and induced impacts.
312. On the basis of a 35 year operation period, the impact is assessed as long term. Due to the ongoing nature operation and maintenance activities, the impact is assessed as continuous.
313. As discussed in section 18.3, impacts are considered across multiple socio-economics local study areas linked to the selection of operation and maintenance port and harbour facilities, and the associated supply of a range of inputs and services.

Secondary Mitigation and Residual Effect

318. The Applicant has committed to enhancement of beneficial effects as per section 18.9. No secondary mitigation is required.

Decommissioning Phase

319. Potential expenditure on decommissioning of wind turbine and balance of plant associated with the Proposed Development could support access to employment amongst local residents in activities associated with decommissioning in the socio-economics local study areas and socio-economics national study area.
320. The scale and duration of decommissioning activity is uncertain. The exact approach to decommissioning is not yet confirmed as best practice at the time is not currently known. It is anticipated that all structures above seabed level will be removed, but subject to review in the future on the basis of likely environmental impacts.
321. No plans are in place to consider potential locations for decommissioning support ports. It is not known if this will be located in Scotland. Given the need for large lay down areas the four ports identified as being under consideration for the construction phase would have the greatest potential to accommodate decommissioning activities based on current circumstances.
322. The Technical Report (volume 3, appendix 18.1) notes that the workforce for the decommissioning of the offshore parts of the wind farm is likely to be supported in a similar way to installation and commissioning. However, the scale of activity will be reduced given the intention to leave cables in situ.
323. On this basis the magnitude of effects would be lower than those set out for the construction phase under the baseline and enhanced scenarios.
324. The significance of effects assessed at construction phase for access to employment amongst local residents in manufacturing, construction, and installation activities are set out in Table 18.61   Open ▸ . On the basis of currently available evidence the significance of effects for the decommissioning phase will be no greater than minor beneficial significance across socio-economics local study areas and the socio-economics national study area. This is not significant in EIA terms. Invergordon socio-economics local study area is the single exception, where the significance of effects for the decommissioning phase will be no greater than moderate beneficial significance. This is not significant in EIA terms.

Impact on the Demand for Housing, Accommodation and Local Services

325. The potential for demand will arise through the temporary, medium term or permanent relocation of workers into socio-economics and tourism study areas.
326. Temporary is defined for this assessment as a period generally measured in nights that would typically be accommodated within a hotel, hostel, guesthouse or bed and breakfast type environment. The worker would be expected to travel alone without family.
327. Medium term is defined as a period generally measured in months that would typically be accommodated within rented accommodation. The worker would typically be expected to travel alone without family.
328. Long term or permanent relocation is defined as a period generally measured in years that would result in the worker relocating to the relevant area with a long term housing solution alongside their family.
329. This impact is applicable to the construction, operation and maintenance, and decommissioning phases. The assessment draws on the assessment of employment impacts and discussion of workforce issues as set out in the supporting Technical Report in volume 3, appendix 18.1.

Magnitude – Assessment Approach

330. The magnitude of impacts is assessed against the following baseline conditions:

• Potential permanent relocations:

–           total population (2019): comparison with total population to give an indication of the scale of the impact of labour migration on the resident population;

–           total dwellings stock (2019): comparison with overall dwellings stock to give an indication of the scale of the impact of labour migration on the housing market; and

–           total unoccupied dwellings stock (2019): comparison with unoccupied dwellings stock to give an indication of the scale of the impact of labour migration on the housing market.

• Potential medium term relocations:

–           total population (2019): comparison with total population to give an indication of the scale of the impact of labour migration on the resident population; and

–           total private rented sector (2018): comparison with the scale of the private rented to sector to assess potential effects on local housing market.

• Potential temporary overnight stays:

–           total number of overnight stays (2019): comparison with total number of overnight stays (in nights per annum) to provide indication of scale relative to existing market; and

–           temporary accommodation capacity (2019): comparison with overnight accommodation capacity to give an indication of the scale of impact of demand from temporary workers.

Table 18.68: Magnitude of Impacts on the Demand for Housing, Accommodation and Local Services Assessment Criteria

Sensitivity – Assessment Approach

331. Sensitivity of employment impacts is assessed against the following baseline conditions:

• policy environment: whether relevant policy environment has the aim of protecting and strengthening local services and the housing market;
• stakeholder comments on previous experience of impacts arising from effects of contractor workforce; and
• scale of change of receiving environment in recent history.

Construction Phase

332. Potential expenditure on activities associated with the construction phase of the Proposed Development could support temporary or medium term labour migration into socio-economics local study areas.
333. A maximum 96 month construction period has been assumed throughout. Although not all impacts will occur for the entire duration of the construction period. Any variation is described and aligns to the anticipated construction programme.
334. Under the baseline scenario it is assumed that procurement decisions are taken in line with current competitiveness of the Scottish offshore wind sector. Employment related to the balance of plant manufacturing and fabrication is assumed to draw on the standing workforces of existing enterprises. This will not have any impact on the demand for housing, accommodation, and local services above current baseline activity.
335. As set out in the Technical Report (volume 3, appendix 18.1), there will be a range of installation and commissioning roles filled by mobile workers, as is typical of all offshore wind projects. Within the baseline scenario these roles will be largely offshore with workers accommodated within SOVs. However, these workers have the potential to give rise to demand for temporary accommodation at the start and end of typical two week shift periods at sea.
336. The potential demand for temporary accommodation, as measured in nights per annum, arising from the Proposed Development are set out in Table 18.69   Open ▸ . The maximum estimated number of overnight stays per annum is calculated based on the following assumptions:

• maximum activities within a single Socio-Economics local study area;
• maximum vessel numbers;
• vessel crew size (including technician and marine crew);
• shift arrangements (assumed two week on/off shift pattern);
• shifts per annum (based on construction programme);
• nights of accommodation required per shift (assumed maximum two nights per shift, including one night before and one night after shift period before travelling to home location); and
• it is assumed that a minimum of one third of workers would not require local overnight accommodation.
  337. Under the baseline scenario the main construction staging port is located outside Scotland. However, other installation and commissioning activities could be located at the ports under consideration. The maximum impact associated with any single port derives from inter-array cable installation. Further impact will be created across the rest of Scotland associated with other installation and commissioning activities.
  338. There is no anticipated medium term relocation of workers into any of the socio-economics and tourism study local areas or the socio-economics national study area.
  339. No permanent relocation of workers into any of the socio-economics and tourism study areas is anticipated under any of the scenarios during the construction phase.

Table 18.69: Potential Maximum Demand for Temporary Accommodation, Baseline Scenario – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Source: HJA analysis of BVG Associates (2021).

Magnitude of Impact

340. Following a review of the anticipated construction programme the period of maximum temporary accommodation requirement will extend across four to five years. This is assessed as long term.
341. As discussed in section 18.3, impacts are considered across multiple socio-economics local study areas linked to the selection of construction ports, and the associated supply of a range of inputs and services.
342. The assessment is based on the maximum potential effects as set out at Table 18.31   Open ▸ . Impact compared to accommodation capacity is estimated based on average unutilised hotel room occupancy. This is a proxy indicator. As per Table 18.70   Open ▸ , there is substantial unutilised capacity across a variety of accommodation types.
343. Impacts are assessed as beneficial, creating demand for temporary accommodation within identified levels of available capacity in each socio-economics local study area and the socio-economics national study area.

Table 18.70:  Magnitude of Temporary Accommodation Demand, Baseline Scenario – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

344. The magnitude of impact, relative to the baseline for each socio-economics local study area and the socio-economics national study area is set out in Table 18.71.

Table 18.72: Magnitude of Temporary Accommodation Demand, Baseline Scenario – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Sensitivity of the Receptor

345. The temporary accommodation sector forms part of the wider tourism sector which is a policy priority across each socio-economics local study area and the national socio-economics study area.
346. Occupancy rates of temporary accommodation are subject to substantial variations on an annual basis. Normal fluctuation is substantially greater than the assessed scale of impact.
347. There is excess capacity within the temporary accommodation sector based on annual average and peak month (minimum 10%) occupancy data.
348. Multiple stakeholders indicated that there had been no adverse impacts as a result of previous similar projects with temporary contractor workforces requiring short term accommodation.
349. The sensitivity of impact and associated justification for each socio-economics local study area and the national socio-economics study area is set out in Table 18.72   Open ▸ .

Table 18.73: Sensitivity of Demand for Housing, Accommodation, and Local Services – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Significance of the Effect

Table 18.74: Significance of Construction Phase Employment Impacts on Demand for Housing, Accommodation, and Local Services – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Secondary Mitigation and Residual Effect

351. No socio-economics and tourism mitigation is considered necessary because the predicted impact in the absence of mitigation is not significant in EIA terms.

Alternative Scenarios

352. The core assessment set out above has been undertaken on the baseline procurement scenario. The same approach has been undertaken to the enhanced scenario, as defined in the supporting Technical Impact Report (volume 3, appendix 18.1). This assumes an increased share of UK and Scottish content in the supply chain within the construction phase, so beneficial effects are greater.
353. Capturing additional balance of plant manufacturing and fabrication activities is predicated on new investments such as the Nigg Offshore Wind factory and XLCC cable factories at Hunterston. If contracts are placed with ports such as these, this will support/safeguard employment for their workforces that would be expected to be permanently resident in the labour market catchment area of the ports.
354. Under the enhanced scenario a Scottish port is selected as the primary construction staging port. This will have impacts on both temporary and medium term accommodation and housing within the socio-economics local study area of the selected port in addition to the impacts assessed under the baseline scenario.
355. The use of a Scottish construction port will include an estimated maximum 200 workers based on land, requiring accommodation in the vicinity of the selected port, as well as additional temporary demand associated with the shift patterns of wind turbine installation and commissioning and marine crew working offshore. The estimated impact is summarised in Table 18.74   Open ▸ .
356. There will also be additional temporary demand for accommodation in the rest of Scotland as a result of further additional installation and commissioning activities being located within the country, but not at the primary construction staging port.

Table 18.75: Potential Maximum Demand for Temporary Accommodation, Enhanced Scenario – by Socio-Economics Local Study Areas and Socio-Economics National Study Area

Source: HJA analysis of BVG Associates (2021).

357. Assessment of temporary overnight accommodation impacts is undertaken on the same basis as for the baseline scenario.
358. It is assumed medium term accommodation and housing needs will be primarily met through the private rented sector. Based on the construction programme demand for accommodation is likely to be across two periods, the first of 18 to 20 months, the second of 12 to 14 months. It is estimated that workers will either rent or be provided with accommodation arranged by their employer in small groups. A maximum of 50 dwellings within the relevant socio-economics local study area is therefore used for the assessment.
